“Nice big cog”. My new greeting on the trail. Sounds great with my Boston accent, too.

I currently have a 1x9 on a touring expedition bike, I'll change it to 3x8

2by is the best.

that's a lot of miles

They make good videos but that's going a bit too far.

What's a 4x

Seriously! I'll always entertain a 3x crankset. I'm considering a 52t option inlined with a 13-34 freewheel from sunrace...

Looks like with the rise of wide range cassettes people are forced to seek out half-step gearing which works even with electric shifting.

I only understood about .5% of what you just said, lol. That's why i love these park tool videos they break the stuff down enough so that even idiots like me can understand it, lol.

Do you need a new chainring bolt or yyo can use the old one?

@@elieserobillo6600 if you make this change using the old middle cog that was on the front chainring, you may indeed need a shorter chainring bolt.

How

same. I never used the highest or the lowest front gear, mine was always in the middle so going 1x was a no-brainer for me.

@@NonLegitNation2 Yep, me too. I'll be making the switch on both of my GT's here soon.

Carlos... how do you like it?

Lol..so true..I felt the same way

We're telling our age...lol..all im going to say is 1977 was a good year...lol

dont forget to make it a fixie as well!

And than send more money to your surgeon when it's time for total knees replacement at young age.

Certainly less blood getting to my brain after watching that.

BMX bikes have 1x1

that's a track bike. you need a trail bike with gears for a proper ride.

I think you meant skill saw blade

I mean the biggest is really good for the fire roads connecting trails. But your forgetting with 3x is like 2x but more chainslap.

Check out Park Tool Webpage, they got some professional bins.

Check their website you will find the B-I-N1

Nooo I want that bin. Haaaaaa

Do you use any chain guards or otherwise any rear derailleur with clutch? The choice of RD with clutch is very limited on 9speed. I plan to switch to 1x9 from 3x9 for simplicity reasons

OK. Since i watched this video i'm thinking on a daily basis to convert to 1x. The scale of 1x is impressive. And is duplicates on 3x are a bit disturbing :)

Haha, that's awesome. : )

@@dawbi its called evolution and technology dummy. the ONLY scam in the bike industry now is the shitty suspension on sub $700 bikes. the suspension doea nothing and adds 4-5lbs to the bike and raises the price point, which is made up on cheaper drive train componants.

@@crabtrap yeah I always shake my head when people talk about bike manufacturers scams. Money talks, they only sell what people are willing to part with their cash for. It's a Consumer driven industry.

@@MrBJPitt but the lower-end consumers are pretty stupid.....do they really think a walmart $99 'full suspension' bike is "almost as good"?

@@crabtrap and your point?

Any update? I'm restoring my ~1986 Trek 830 that has a 3x6. To be a greenway / gravel bike (no big climbs). I'm wondering what you went with.

converting actually cost more money ,those with 11 -12 speed cassette is expensive

There aren't any steep hills where I live ( not for a long distance) .so on my 3x7 with 14 to 28 on back , I use mostly 21st gear . On a few hills I shift down to 18th . And some to 19,20 . But going down hill in some places ,I can't pedal fast enough to keep up . One more high gear would be nice .

I have the same set up. I ride distance (commute an hour each way) I ride offroad for sport (it's an mtb), I go to the shops on it, go camping.

I will never ditch my 2x! It’s just fine as frog hair! Sometimes I ride to the bike trails on the road and bieng able to jump 4-5 gears with one click of my left thumb is not going away

what left shifter do you use?

A standard wide range cassette is available for 10 speed from Sunrace. Might be worth a look. Best of luck!

I feel the same way. The 1x seems kinda gimmicky to me. I have a cannondale slate and the 1x version of my bike is outrageously more expensive just for that drivetrain.

It's an identical compromise. If you want to make a big shift, it requires 2 hits of the 1x sram double tap lever to shift up 6 gears while it only takes 1 hit on the front mech to get the same big gear change. While if you want a small change but to shift chainrings it requires a shift on the front and back, while it only requires a shift on the back with 1x.

there's dozens of us!

What bike do you have

I'll probably be sticking to a 3x7

@@bananasstuff3344 My Bike came with a 3x8. When pulling a trailer up a hill, i am rather thankful for that small front ring, and i likes my top end speed. Using 1 bike for all the things that need doing, it better have all the gears.

@@seven9766 yes mine has to be an MTB and a good bike for everything else as my family often goes on long day trips on bikes

Mountain Goat Allen how was ur 1 by 9 on uphill ride on easy gear

@@satimlimbu1983 It was not to bad maybe a bit harder on tech Climbs

Mountain Goat Allen thanks for reply I have 3 by 9 playing to change it to 1 by 9

@MotorcycleMan 32T and 10-51 cassette, still lower ratio than 38/28 11-36 downhill.

I do most of my mileage on a trekking/touring bike, and when I travel longer distances, I usually travel pretty heavy with all my camping gear. The 26/36/48 didn't cut it for me and I don't see the point in that gearing. Even after switching to a MTB crankset with 22/32/44, I'm not using the two small rear cogs (which would require 20+ miles per hour) at all, but I'm definitely using the low end when the going gets tough, especially near the end of a long day in the saddle. Ditching the 26/36/48 was one of the best decisions I've made for that bike.

Jeff Ahlers LMAO I do all of the above

XC racers are all on 1x drivetrains

Ya lost me.10x42 is 420 gears.Maybe SRAM 10-42t?

It was good but I find it depends where you live at or where you ride at, is it hilly or is it mostly flat and moving fast down hill can get you killed. I mostly coast downhills anyway it helps me cold off

Sadly the steep chainline and it's associated problems can be reduced , but not eliminated to the same degree as a 2 x or 3 x configuration would allow . This 1 x concept is more about allowing exotic frame designs than versatility . Also the simplicity and cleaner look .

The reason to use all three of the large cogs is that it reduces the wear on drivetrain and saves energy pedaling due to the angle of the chain with less friction at less extreme angles. the smallest front cog and smallest rear cog or largest front and largest rear cog causes the chain to flex from near the frame on the front cog to the most outwards rear cog near the axle bolt and vice versa. The amount of watts you lose isn't much but the money you save is going to play out on highend components. Hope this helps explain the disadvantage of using the largest cog and not downshifting to a less extreme gear setup (largest front/back cogs, smallest front/back cogs).

Chainline definitely comes into play when converting. When pedaling backwards on a wide range rear cassette it is not uncommon for the chain to fall down a few gears even with proper chainline even on stock 1x setups that were not converted.

ayy

You a bad man

Hahaha xd

lol

gross

True, the most cost effective bikes are 3 by 9. those rear cassettes cost peanuts compared to 1 by solutions. here arround 25 euro's compared to 80 euro's. Meaning as a rental service i will not make the jump at current prices. however 2 by 10 is cheap enough. 11-42 10 speed casettes are 35 euro's. Those can work fine with 2 by drive trains. 1 by 12 10-51/50 casettes start at 80 euro's. That's just too much.

Taurusdre for real

Good point.

But isn't it correct that crossing the front and rear (example, 1 in front and 8 or 9 in rear) deteriorates the chains lifespan? At least that's what I've been told.

Taurusdre, That's what I don't get either. It is obviously a step backwards, there's a reason 2x and 3x were invented. We all used to ride "1x" after all. Now obviously having more options with the cassette today means you can get more gears out of a 1x, 2x or 3x than we used to but still not *as* many gears with a 1x. I remember my first MTB was 3x6 so that was 18 gears, you're not getting that on a 1x but you can get that from a 2x today. The 1x is quite clearly driven by marketing, the benefit of having more gears hasn't suddenly vanished overnight. If your way of riding fits the gears that a 1x offers that's great for you and then you may choose to go for the simpler and cleaner look but you *are* missing gears that people on 2x or 3x have. If you're climbing and find the 1x granny gear just slightly too low you're pretty much out of luck as the next gear is usually quite a fucking jump away from the granny gear. On a 2x or 3x you can make smaller adjustments to fit your preferred cadence. Of course you could just add more granny gear options to your 1x but then you'll be missing out at the other end when it comes to riding really fast on flat terrain, gravel roads, even normal tarmac roads or whatever, *or* you'll just have massive jumps between other gears. No matter how much Sram spends on their 1x marketing you're never going to get the same out of it as you can get from a 2x or 3x, period. What really annoys the hell out of me about the 1x though is the pricing. It's a simpler fucking system. They save a ring up front and the entire front derailleur and mounting for it, it shouldn't be a fucking "Premium product", it should be a cheaper option for people only doing bike parks with shuttles, lifts etc. as they obviously don't need gears to nearly the same extent as other riders do. The manufacturer is *saving* money on a simpler setup and marketing it as a more expensive product. That really pisses me off.

I understand what you are saying Taurusdre, but until you try 1x, its hard to knock it. My new bike came with 1x12 gx eagle, and I honestly cant fault the range of gears it gives me. I still have a 3x10 xc bike, but the chain slap and extra noise is noticeable whenever I ride it. Personally, unless you are getting a new bike, I dont see the point in upgrading.

Hub space for cassette is limited, so it will limit maximum number of sprockets in the back. With more sprockets, the cog pitch will become thinner and thinner until it reaches a hard limit and the chain will become progressively thinner as well. Will there be a future with 22 sprockets, I highly doubt it; anyways, there is no practical reason to have so many gear ratios.

@@misternobody4644 357mm hyper boost³ plus, so the freehubs are probably gonna get wider as well.

Mister Nobody it is a joke

Max out the B screw and buy a derailleur extender off Ali Express for $2.

Pascal Godin hello can you advise how you did this I have a 2x10 Tiagra on a trek checkpoint

Currently have a 3x8, 1x10 or 1x11 seems like an expensive endeavor…

My two bikes were 3x at front, little ring gone off, and limited screw turned the 3 gears into 2. Done. I learned it when one mechanic did it to one, and now I fine tune it, it runs perfect.

@@tonysadler5290 at least in the US, the 3x system is definitely more prevalent among 'big box store' cheap / entry level bikes (walmart, target, toysrus, etc) probably for the sole purpose of marketing HIGHER SPEEDS, MORE GEARS, BIGGER IS BETTER bs. I guess with the core demographic being non-cyclists or recreational cyclists that use their bike once a year, they're gonna be using the lowest gear set for the slightest hill and largest gear set for downhills, if they actually learn how to shift properly in the first place.

which is better for going climb uphill? 3x9 or 1x12?

@@PunxTV123 I prefer the 1X12, but it's hard to generalize..

I live in Winter Park, Colorado and ride real mountains everyday. I'm on an 80s 5 speed cassette, 1x. Shifting with my legs.
