A majority of race bike purchases are by people that don’t race. There’s a disparity in fitness level with the racer. A 50-34 compact chain set is definitely better for the average rider. Higher end race bikes usually come with a mid compact chain set, which seems to be a good compromise. Most endurance bikes I be seen come with a 50-34 which is good for the majority of the people that buy those bikes. I’m a fairly fit 64 year old. I ride a Giant Defy which comes with a 50-34 and an 11-32 cassette. I really appreciate the lower gears when grades reach double digits. Compact cassettes may be dead for elite racers but not for the average consumer. We are the ones who actually pay for our bikes!

Just because it might be falling out of favor for new trend chasers/pros, doesn't mean it's dead to a large amount of riders.

I am a 62 year old fit Cyclist living in hilly Yorkshire, I could not do the rides I do without a 50/34 and an 11/32 on the back, on a fast decent I just stop pedaling !! so no spinning out, 35 to 40 mph down hill is fast enough for me.

It's funny how the only people wondering if the 50/34 is dead are those with a 300 watt + FTP and weigh the same as my left nut! I went to the Alps for a week of cycling last September, I had 50/34 chainrings and an 11/34 cassette! I can assure you I was not spinning up anything! At the time I was 87 kilos and had an FTP of 220 watts (2.5 watts per kilo), frankly I found myself grinding my way up most climbs! While my watts per kilo has definitely improved since I still couldn't imagine myself being able to survive with a 52/36 on a long climb and I can only imagine there are plenty of people out there who would find it even tougher than me. Long live the 50/34!

not only that 50/34 isn't dead but the industry needs more sub compact options for gravel and adventure bikes like 48-32 or 46-30

Back when I was a younger chap, it wasn't uncommon to ride 52/42 with 12-17 or 13-18 at the back. This was the late 70s/early 80s before electricity had been invented, everyone had ricketts and infant mortality was around 99%. We rode up hills, but I cannot recall how.

Maybe that's the trend for the pro's!! Do you guys even ride in the real world... Compact is here to stay!!

Haven't had the pleasure of spinning out a 50/11 so I'll stick to my 50/34-11/32

What is missing at the moment from gearing options are cassettes that start with a 12 cog 12-30/32/34. The 11 is rarely used for most people and I would much rather get a 16 cog on a 12-30 to get closer mid ratios than an 11 that will be seldom used. The 11 is really only practical going down long descents. A 50-12 combination is plenty to go over 50kph without spinning out.

Man that rides bikes as a profession, an likely experiences greater physical fitness, claims compact dead. SRAM and Shimano are correct, gearing is a personal choice determined by the needs of the rider. If mid-compact is so great, what explains the availability and people buying aftermarket sub-compact? The only dead chain-set is full pro.

I live in Devon and run a 50-34 with a 11-34 cassette , spinners are winners 😋

Probably the best summary of this topic that I've seen. I do get a little frustrated when arguments are based around the big ring. The reality is that 50 vs 52 is a 4% change when cassette steps are generally around 7%-14%. Big ring size is really just based on what the front derailleur can handle relative to the small ring that you need for your easy end of things. Yes, there are subtleties but they only really concern people who already know what they are. I'd contend that magazine articles do the majority of consumers a disservice by suggesting that they need anything other than a compact. Unless you're racing or riding chain-gangs then it's unlikely you actually care about the small speed benefit of a larger big ring on the occasions you spin out your 50-11 gear.

The opposite is true! Among the gravel grinders, they are moving to super-compact (48/32), which I think will probably creep it's way into road bikes too.

53-39, may indeed make a come back with 12 speed road groupsets, you could run a 12-34/12-36 with the big rings and it would give you bigger tooth counts wrapping around the front and back gears which are more efficient and reduce chain and gear wear.

34x30 at 90 rpm is 13.00km/h 36x30 at 90 rpm is 13.80km/h so compact chainset is not dead yet...

A systematic approach is to use power output and weight to predict your cadence on an incline. For example, a not very fit 70kg person putting out 210W on a 10% incline is going less than 9kph, which means less than 55 rpm cadence in a 36x28. That cadence seems too low, so that gearing is inappropriate if that person has to deal with long steep climbs. Note that the above gives a power to weight ratio of 3.0, so almost exactly half of top professionals, so it is logical to use half the gear size of professionals. This generalizes to other power to weight ratios. I therefore propose that the solution is for an amateur rider to estimate his power to weight ratio A and use an A/P proportion of top professional gearing, where P is the power to weight ratio of top professionals. -ilan

6:40 - Attention World Tour teams: big shot here can spin out a 50x11. Here is your leadout man.

Moved from compact to semi compact with 11 32 rear cassette....great improvement and range...love it 🙂

I find myself going smaller and smaller on my front chain rings as I'm a climber and prefer more choices when going uphill. My latest experiment is with a 42-28 up front and an 11-30 in the back so I have a lot of choices to spin uphill (I often ride routes that include tarmac, dirt, and gravel with grades over 25% on 35 mm tyres). With this setup I can go faster than most uphill, often passing younger guys on lighter bikes (and mid-compact or standard cranks) by virtue of gearing choices and efficiency when compared to their raw strength. Forget about pedaling downhill, but I'm 50 and don't feel the need to go faster in that direction. So, 'standard' road cranks are useless to me.

We were using 52/42 chainsets back in 1987. Nice to see the 52 back again

Love spinning, not grinding. Currently looking at sub compact!

On my 10-speed Cannondale Synapse Carbon I've swapped to the *OPPOSITE* riding 46/34 11-40 from the stock 50/34 11-28. Spin spin spin for two reasons: 1) I simply don't have the knees to grind going up the numerous short, honest 15-22% grades I have around me 2) I have rarely needed even 50 x 11. I neither have long enough mountains, nor do I typically ride group rides where I would ever use 50 x 11, let alone SPIN OUT 50 x 11 at 70kph needing LARGER chainrings!). By dropping from a 50t to 46t chainring (near identical to a 50 x 12); I now have USE of my upper 11t cog! Before, I my has well have been riding a 9-speed 50/34 x 12-28t. The combination of 46t chainring with an 11-40t cassette I now have gained both a 40t bail-out gear for extreme grades (No more walking or grinding! Yay! and spinning is still far faster than walking!) and I can actually ride & get use on 24t, 28t & 34t gear on long/hard rides where I'm gassed or simply need to cruise around on. No worries about cross-chaining, no worries about having to drop out of the larger chainring or simply not having the gearing. Sure! Having a huge efficient 56t front with a 12-49t rear would be more "ideal" for me in an efficiency point of view, but nobody MAKES that combination!? Meanwhile, anyone can drop on any number of smaller chainrings from cyclocross and multiple companies make wide range cyclo/MTB cassettes that will work just fine on road bikes now. Even older 10-speed ones! (Praxis works 10-40/42 is my favorite because of the better spread in smaller cogs than Sunrace's 11-40/42t version. You can do your own hybrids also). At best you simply pop on a roadlink so you can clear your rear derailleur, at worst you combine a roadlink with a 9-speed mountain bike long-cage derailleur (Shimano) which has the same pull as the 10-spd. Did I *need* to drop compact for sub-compact + wide ratio rear cassette? No, I was fairly happy with 50/34 11-28, but now I get full use of my available gears & by doing so have an easier time riding longer & harder! (FWIW I have some left knee damage and no amount of "bike fitting" or "get stronger" is EVER going to allow any form of grinding up hills.) Frankly, the entire industry would be much more beginner friendly if sub-compact chainrings and wide(r) range cassettes were the normal option most road bikes shipped with. Get that 46/30 rocking on road bike drivetrains! That's the easiest solution, but getting a 30t to fit on modern BB's is impractical! Not everyone has amazing physical attributes or perfect competition fitness combined with riding at the beaches in Florida with endless flat roads & tailwinds where someone would likely get a some use out of a huge chainring & 12-23 or 11-25 corncob!

Imo spinning out on a decent is problematic if you are racing. Regular cyclists should worry more about getting up that hill or especially that mountain.

saying that 50/34 is dead is like saying 100 mm stem is dead or endurance frame, not every cyclist can copy the exact same tooth number and position of a pro cyclist and although we all love bling and expensive stuff if it doesn't fit you then you loose the fun of it

The 50/34 isn't even close to death, nor are rim brakes and skinny tires. I've hit the responsible age where I don't upgrade or change just because the industry twists my arm. Basically, I apply practical, logical reasoning and it spares my wallet in the new fucked up cycling world...

54/39 is def dying. I don't know why any novice cyclist would ride it. I guess maybe the A grade crits. But I'll stick with compact or mid compact every day for riding with my mates.

I run 11/28 with a 52/34. Never dropped a chain. Although I do have a catcher.

Well back on the day(1984) I had 52-42 with 14-23, And I climb every hill.....but I was 15 years old. Now I'm happy and grateful for 50-34 and 11-32...and I have no problem using 11-34 in my flat bar road bike.

MORE LIKE 130 BCD IS DEAD

I’m very much with Durianrider here. I live in Wales with loads of really steep hills, if you’re an ordinary club cyclist, you want as wide a range of gears as possible. It would be great if the ‘experts stopped dictating the development of bikes and listen to ordinary riders.

I've seen road bikes with 46/30 cranksets, 11-40T cassettes, and 32c tires where I live.

I moved from a compact to 52/36 on a friend's recommendation as my form was improving, but soon went back to 50/34. I'm a fairly fit 54 yr old, ftp when in shape 280W, but live at the top of a 1000m climb in the Alps, and the 36 just felt laborious on the climbs with an 11-29. I way prefer to spin a gear on a long climb. I liked the 52 on the flat, but 50 is fine, just tuck it if you're spinning out on the 11. I've now put on an 11-32 for training so I don't have to overdo it every time out - it's a long slog back home, and I find it's better to have a gear in hand just in case.

Just ride a 52x36 chainset with11-32 casette. Supreme range and versatility.

bloke who puts out a consistent 300W declares 50-34 dead. There are a lot of people who are far less fit buying the 50-34 and will continue to do so because it provides the most adequate gear ratios for their fitness. 50-34 is here to stay methinks. It may even get smaller- 48-34 perhaps?

I run 52/34 at the front and 11/32 at the back on all my bikes one on Previois Ultegra and the other on the latest Dura-Ace and it works well without a prob. Great for sprints and long climbs

Hi guys! I really enjoyed this new kind of video series of you guys. I really like your videos, keep it up, congratulations for the content !!!

When I started riding in the late 70's the standard crankset was 42/52 or 42/53 and only a 7 speed cassette in the rear. I rode a 12-22 back then and only weighed 145-150lbs and I was able to climb everything that I came upon. Now many years and many extra pounds later a 50/34 with an 11-29 suits me much better. I do have 11-25's on a couple of wheelsets for when I'm riding near the coast on flatter routes.

I just went to a 52/36 up from a 50/34 on my primary road bike, with an 11-34 cassette in back. Gives me the same low range as with my 50/34 and 11-32, but now I have more top end for long mountain descents and with a 36/34 low gear, I can still keep it in zone 2 on easier days up moderate gradients/mountain climbs. For those insanely hilly rides with steep gradients, I can throw the 50/34 chainrings back on if I want for a 1:1 climbing gear. I'm still running a 50/34 on my gravel bikes though and have no need for a 52/36 on those.

I agree with you, I have a semi compact 52/36 and a 11/32 cassette. I think personally it gives me the perfect ratios for climbing these crazy hills in Spain, also don't tend to spin out when on descents, just perfect for long tough rides AND saving legs, AND saving your back!!! Tougher gears will strip your gas tank/energy for the day, and strip your lower back right off you!!! Thx great info :-) :-) :-)

11-32 with a 50/34 is perfect for me. As someone who’s never gonna race I love having the range to tackle any climb in my area yet still be able to ride at a decent speed on the flats and descents.

Bring back the Triple. Running an old 9 spd DuraAce triple (Utlegra cranks) with 50/40/28 and 11-27 cassette. Perfect gearing. Great range and small steps. The 50/40 step in the front is spot on. 50/34 is just too big of a difference.

No mention of sub-compact 48/32, just throwing that into the mix :)

Just completed a self-build with Potenza running gear with one exception: bought a used Campag Centaur Carbon chainset. The gear ratios: front 52/39, rear 12-32. Yes, the Centaur was 10 speed but I swapped out the old rings for new Stronglight 11 speed rings. Only one issue: had to buy new bolts as the new small front ring uses threaded holes instead of a cup/bolt sandwich. Saved nearly 200g compared to Potenza chainset and nearly £200 for a similiar weight Campag Chorus chainset.

My bike started with a triple and a 12/25 on the back. Swapped the back out for an 11/32 and it is great, my fitness is flying forward and I still have the top end.

They'll have to take my compact and 11/32 away from my cold dead scrawny legs :-D

Thank you for this very timely video. My new bike (2017 Specialized Venge Vias) comes with a 52/36 chainring. If anything you have put my mind at ease. Thank you.

Great show! Question: which setup is faster on aero wheels, narrower 23mm tires on front 28mm on the back or faster rolling 28mm front and back?

Used to ride a 50/34 and 11-30 10 speed as well as a 50/34 and 12-28 9 speed and I’ve ridden up Alpe Du Zwift. Then I got a 52/36 and made the same climb with 11-30. But it was kinda tough. I fitted an 11-25 for road riding with moderate hills. Just ordered a 52/36 and 11-34 for all day adventure riding. Can’t wait!

Great video guys! Can you address cross chaining and how bad it really is for your drivetrain next? I run a Tiagra compact chain set and often find my self spinning on the big ring in the 25 or 28 tooth cog on the short punchy climbs around Denver. How bad is that for my gears?

Great new series. Really enjoyed that. Different enough from the GCN Tech Show to watch both for sure. Thanks Ollie! (and CW)

Great topic, I’m getting ready to build up from a frameset and I’m torn between 52/36 with 11-28 like my current bike or 50/34.

Currently struggling with this topic in preparation for the south of France in a few weeks. Might go medium cage & 11-34x36-52.

I run a campy 50-36, why? Because the problem with a full compact is the 16 tooth gap, it is a pain, it feels rough to change into the big dog. A 50-36 give a smoother change and the same tooth gap as a standard, it is really nice. The campy rings work incredibly well together, i do believe shimano doesn’t play so nicely

I like the 50/36 or 50/38 combos for easy shifting on rolling roads~ I use the 50/34 too which is great for long climbs~ it seems there are endless options these days (:

Nice to see you (no offense) consulted the experts. I enjoyed the in-depth discussion as opposed to 12 questions in 8 minutes.

I ride both a standard compact + 11-28 cassette on my Lapierre Xelius (light bike) & a sub compact (48-32) + 11-32 for touring on my Kinesis Racelight GF-Ti Disc (heavier bike, especially loaded for a bike packing tour!), different horses for different courses. I am 62 years old, 95kg & live in South West Cornwall where the terrain is let’s say challenging. As for going to mid compact on my Lapierre, yes if I lived in an area with less lumpy terrain &/or lost 15kgs off body weight it would be ideal for some but not me. The key here is that I don’t race & my reason for riding is not to go as fast as possible, hence I very rarely ride in the 50-11 if at all so going up to a 52 big ring would serve no purpose, in fact I’ll probably end up riding 11-32 on both bikes and enjoy the climbs, even the 20% - 25% ones! That’s just the way I role. BTW I ride around 100+ miles a week & love it.

I foind this video helpful. Can a granny gear be added to a 53/39 chain ring? I have an 1984 cannondale rs400.. Thx.

In training (and for commuting) I always ride a cyclocross bike with 46/36 in the front and a 12-25 cassette. On the flat I wouldn't want it any other way. When I go into the mountains I change the cassette to a 11-32, which gets me up every climb. I do run 38c road tires, so this increases the ratios a little. For racing (crits with occasionally some small climbs), I have a 52/36 combined with a 12-28 cassette. 52-12 would get me up to 66km/h or 41m/h at 120rpm, which I'll never reach on the flat. On my time-trial and triathlon bike I have a 53/39 with a 11-25 cassette. I have only used this bike on flat roads. I've actually felt most comfortable with the 46 chainring and 12-25 cassette combination, because I really like the small steps between the gears. If the 36 inner chainring on this training bike would've been a 34 it would've be fine too; when I'm going to climb some serious mountains (never in a race situation) I will change to a 11-32 cassette anyways. But... If I would have only one bike to do it all, it would 100% be a 50/34 chainset! So if non-pro riders are going to be rational, the compact chainset will be alive and kicking!

The only ratios that are dead are the ones that don’t sell. There’s a great market for compacts since makers want riders to enjoy at the entry and mid-levels, regardless of the amount of climbing those riders may be facing. With experience, training and learning, some will move to ratios that favor descents when the getting up isn’t as much a factor. Even stronger older riders appreciate higher cadence instead of pounding their joints into dust (and probably equally less concerned with boiling speed on descents). On the pro side, yeah, ratios over the long haul favor spinning instead of grinding, but those large rings also won’t be going away even for the smaller demand among elite and pro cyclists. So, the compact is quite far from death even with mid-compacts serving as a great compromise for those not constantly pounding the mountain.

Great video... Question; would a 54/36 be to big of a gap for front rings? Would this cause shifting problems? I currently use a 52/36 with a 11-32 rear cassette, looking for more top-end speed..

At hilly Gran Fondos the majority of riders coast above 50 km/h, so 46/11 is still more than adequate. At the same time, they would definitely benefit from a 34/32 bottom gear, as they struggle riding up inclines above 10 % with 34/28 or 36/28. Bottom line: Road bikes in their stock setup are rather overgeared more often than undergeared. Personally, on a hilly solo ride with 1500 - 2000m of climbing per 100 km, I can still maintain an average speed well above 30 km/h. I'm happy with 50/34, 11-30; it gives me all the range I need to tackle gradients of 20 % and still put some pressure on the pedals at 65 km/h (A proper aero tuck is the choice for descents). 52/36 chainrings will be mounted for occassional racing.

I'll keep my compact and 11-32, it happens less that I spin out on a descent than I climb on steep hills and love the 34-32 combo!

My bike has 53/39 x 12-25 on it and I do struggle with any long climbs over 4%. My next bike will definitely have 52/36 and a wider cassette so I can have higher top end and lower bottom end. I also see the need for the compact for really hilly terrain, and also standard for really flat terrain.

I ride a 52-36 but at times I wish I had a compact, for the really steep stuff, 15% + climbs. I guess it just depends what type of rider you are (spinner or grinder) and what type of terrain you ride most.

I recommend swapping out your 50T/53T with a 46T chainring.

I surely hope it's not dead, and even if it is, I hope sub-compact cranks will become more and more popular. To me, the ideal crankset is a 46/30, paired with something like an 11-26 cassette for everyday riding and an 11-32 for dealing with proper mountains (which is definitely the main reason I ride my bike, in spite of being far from lightweight at my 86 kg). But those cranksets are still quite a niche product, are hard to find and usually bloody expensive compared to equivalent compact cranksets. I hope they become more popular, so that I won't care anymore what happens to the compact crank.

Having a compact alongside an 11-42t fitted to My bike this week :) Spinning for the climb baby ,,,

i got a 50/34 with a 11-25 setup like mentioned in the video. My problem is that im a really bad case of "spin to win". 110rpm in a TT-effort is nothing too extraordinary to me. But this means that i really have to have a low gear for the climbs(i simply am bad at putting down torque). on my mtb is got a 32t and a massive 11-46t cassette and still find quite some hills where it would be nice to have a easier gear. Soon i will slap on a 11-32 on my roadbike, but descending is quite...strange. Since i spin out at 84km/h donwhill, i can at most maintain a cadence of 120rpm for descending. This results in 68km/h without blowing up immediately. Unfortunately many parts of my favorite descent are much faster than that. i will consider a 52/36 in the future, but with my cadence type i can't convert that simple to mid-compact

I run a 50/36 it's great for climbing and my shifts in the front are a lot smoother as gears run closer but yes on downhills or flats I do spin out with only a 50 tooth I always have to push a bit harder to stay in the group

Ollie, what about having a second set of chainrings for my Shimano 9100 crankset. I could have 52x36 for flat/hilly rides and 50x34 for when I go to the mountains?

I stand 170cm tall and currently riding my selfbuild roadbike using a De Rosa Planet frame last year....I would like to ask regarding cranklength to chainring matching...I do have inseam of 77cm, currently using a dura ace FC9000 crankset 170mm length 53/39T chainring . Is it advisable to use a 50/39T combination to improve my cadence

The real trouble with any of these compacts is that the 'just riding along' gears are cross-chained in either chainring = inefficient and lots of front shifting. A 39-42 chainring is perfect for 80% of riding... hence the middle ring of triples or the inner ring of racing doubles for powerful riders who spent more time at high speed... or the front ring on many 1x setups. While I welcome the new 30/46 chainsets I think this will still be somewhat of an issue for 700c bikes. I took a punt when building my do-it-all 700c 38mm bike and put a 28/40 mtb crank on it... 1x with a granny gear for light touring in hills or 15%-30% climbs. Just because I could potentially pedal faster down a big hill doesn't mean I need to. The free-hub is a great invention.

I currently run an old 8 speed 53/39 with a 12-25 and it has been fine up to now. However, with more riding in hills I've bought a replacement 52/36 with an 11-28. My brother has this setup and I can easily (relative term) get up 20% hills on his bike, I would currently probably get off and walk them after 200m on mine. Everybody's different, try em out and see which you like, there's no wrong choice. Don't let machoism sway how you feel comfortable.

All 3 combinations across 3 different bikes, but still racing at 50 on a 53/39. Back in the day we would swop out chainrings for different races, 54/44 with 11-25 was a favourite for courses with 6% or less inclined.

I’m currently riding a 50/34 with 11/32 at the back, I find it hard to keep up with the group on flats, would changing to a 52/36 help?

Do they do XD driver body on road bikes? The 10-42 on my enduro would give a good range or is it 100g too heavy for roadies in general?

I live in a hilly area so to get home I've got many 10%+ pinches. On one 12 to 13% stretch I need to put out 300W to maintain 80rpm's in my 34x28. If I shift to my 34x32 I only need to put out 250W to maintain the same 80rpm cadence. A god send when I'm tired. On a 3km 10% average climb if I'm tired, or on an easy recovery day even in my 34x32 I'm down to a cadence in the high 60's at around 200W(~3W/kg for me). Most recreational cyclists can only ride at about 3 to 3.5W/kg for any length of time so in my opinion the vast majority should be on a compact unless they live in a flat area. That 34x32 ratio makes steep climbs so much easier and enjoyable. You don't need to use that smallest gear but its great to have the option. I could get away with a mid-compact but would need at least a 30 on the back for the climbs around here.

I have a compact and live in a hilly area and changed my cassette from 11-25 to 11-32. What a great change! However, as I get stronger I begin to want a higher gear, and feel I could probably live without the lowest. I wonder how great a difference going to 52-36 would make?

I ride 36 52 with 11-28 on my canyon aeroroad and on my climbing bike which I built from scratch 2009 focus Cayo I ride 50-34 with 11-32 and rode some crazy stuff with no problems at all

53-39 front and 11-36 back here, with a short cage and dérailleur extender, living in a very steep area. Would probably swap for 52-36 and 11-32 at some point.

The average consumer doesn't need an eleven tooth high gear with a mid compact 52/36 chainset. Shimano please give us 12-32 and 13 -36 cassettes please...

Correct, I have a lot of hills In my area so I run a 52/34 and you do need to be careful dropping down. You need to make sure that you are in the middle gears on the rear cog. Other than that, it’s fine.

I think it’s missing the point a little. The idea behind the compact was that the 110bcd gave you more choice with a min 34t small ring vs the 39t min on a traditional 130bcd crank. You can always fit larger chainrings than minimum size, but not the other way round. Thus you can fit 53/39, 52/36 and 50/34 all on a 110bcd crank. It’s about choice to match riding style, terrain etc.

I ride a 52/36 and 11-32 at the back. The 32 cog is very useful for 15%+ gradients or when I'm really tired

72 year old cyclist here who regularly climbs steep hills here in Cambodia. I use a Giant FastRoad flat bar road bike with 50/34 compact in front, and 11/42 11 speed casette for the hills. It's like having a 10 speed cassette with an extra climbing gear the size of a small dinner plate. The cassette works with an XT shifter and derailleur.

In my flat country I always rode 53-39, getting older 52-39…,though. I climbed with 50-34. Nowadays with 52-36 (and 11-34) climbing is superb, and for the flat country I only change the 36 for a 39. More practical than a whole compact investment…

I did a few calculations relating to gearing before I decided to add a longer cage derailleur to my kit so I could run a 32 tooth cassette with a 53-39. The cost to me to achieve that gear ratio versus switching to a different crankset was much lower. Personally I feel like what we really need is a common BCD for the front where we can run different chainrings from 54 39 down to a mid compact or even compact.. I think Shimano might do this now? There is no one answer. So for us that are mechanically inclined having all the options is good but making the changeover from one to the other a simple process would be fantastic.

Talk about 1x setups and what’s needed to convert from 2x to 1x. I’m debating on switching to it next. Where I live with rollers and mostly flats, I almost never use the small ring. Worst case there’s 2 min climbs and I cross chain in 52x28 for a short period.

Its a funny old world. I'm thinking of going for a sub compact 48/32! I don't need to worry about spinning out as I approach 40mph but I'm always up for another gear when gong up hill!

Hi! Is it possible to run a 53-34 chainring? And how can I do this set up?... I am using Ultegra 6800.

ideas for future videos? crank length. how big a difference does it make?

Can you do a 53/39 for top end as I spin out on the down hills, but a 11-32 cassette to counter the bigger front small cog. Will it work and give best of both worlds?

50 x 34 and a 11 speed 11-25 cassette on the rear .. gets me up almost all the grades here in Chiang Mai, Thailand, though there are still a few climbs I wished for a 29...!

I’ve got 34 chainring and 34 cassette on my winter bike. My venge has a 36 smallest ring and currently a 11-28 on the back. Been really grinding the last few weeks. Think I’m going to get a long cage mech and a 11-34 and just keep the chain set as is. Don’t intend on going super slow, but also don’t want to be struck grinding away hurting my knees while I’m not at my fittest!

I ride a 50/34 with an 11-30 in the back. I'm a 4w/kg rider (non-racer) and I prefer to spin instead of grind up hills. I can spin out the gears but only on fast and straight descents. I almost never use the larger cogs but they are there as in insurance policy. I could probably go with a 52/36 but I'm happy with my current setup.

If your group rides trend to be on the fast side, the 53-39 is the best option, and deppending on the route, you can switch, freehubs from 11-25, 11-28, or 11-32, that extra tooth, can make a big difference if you have the power on the legs, if not, yes, stick to 52-36. And for the new bike riders, the 50-34 is a must, ride those chain rings for the first 8 to 10 months, then think if it really is worthy change to 52-36, deppending on the terrain you ride, the speeds of your group rides, and your fitness.

My Specialized S-Works Tarmac has a 53/39 chain ring and a 10 speed 12/28 Cassette. I'm surrounded by hills and I'm no pro cyclist. In some climbs i really struggle to maintain cadence. I guess i will be changing my Cassette for a 12/30 or 11/32?

One tech question benefits of Cross baking the FD and RD vs standard straight cabling ?

I think a 50-34 is also a good option for a lighter rider as well. I'm 64kg and hate having to move down to the 34 on small inclines of 3-4% preferring to cross chain a little down to third biggest cog before conceding (I find it more efficient staying in the big ring). Therefore, if I were on a 52 I would need to drop down more often.

i use a compact chainring and an 11-23 cassette on my Trek Speed Concept. i find it plenty fast and flexible for hills too. if the grade is steep enough i go 11-28
