Years ago, just out of curiosity I counted all the teeth on front and rear cogs and made up a spreadsheet calculating the effective gear ratios on a 3x9 rig. One thing I found that was not mentioned is that several of the ratios were actually identical. So the number combinations was 3x9=27 actual ratios available was 20 and if you round the true ratio to one decimal place then there were only actually 18 different gears and of course some of those would be unusable due to bad chain lines.

The cheapest conversion from a 3x to a 1x is to just not shift out of the middle chain ring

As a city cyclist who likes to sometimes go fast but lives on a steep hill, I appreciate my 3x greatly. Also cheap is nice. Had no idea 1x drive trains were also less durable until now though, that's interesting

I have been MTBing for about 28 years and recently thought about changing my old 3x9 26er mtb just for the whole reason of being up-to-date but after carefully analyzing what gains I might get from modernizing, I figured all the things you said-quick downshift with one flick when faced with a sudden steep climb, maintain better cadence (esp on those long uphills), straighter and more efficient chain line, and, to me, front derailleur use is really not that complicated and the weight savings is not that big of a deal. So I kept the 3x9. Besides, I don’t wanna throw away my XTRs after spending so much money in upgrades a few years back. The 11x36 cogs in the back and 22t up front lets me climb anything.

The chain retention point is actually really interesting, since it makes total sense but isn't something I would have considered!

Next minute: Seth explains why the throttle shift is superior.

I've got a 3x on my XC bike, and I love it. It shifts really well and gives a massive range. I can crawl up hills.

Personally, I like 3x for road biking because you can treat the chainrings as uphill, flat, and downhill sets of gears respectively. Also, on 2x and 3x you can shift to the smallest ring when approaching a red light and it’s very easy and hassle-free to start up again. The fact that I run friction shifters probably has a lot to do with this haha

I'm an racer, full time cycling coach, and use a 2x, even though it's a bit unorthodox is the pro field I'm racing in. I understand the 1x advantages, but I prefer smaller steps between gears so I can dial in my cadence.

Seth's daughter: hey dad what's the difference between 1*1 and 1/1? Seth: a little different but kind of the same

I'm coming from a 3x 7speeds. In its years of use, I realized I almost never used the smallest gear on the front drive, so when I looked to buy a new bike, I knew I wasn't going to miss the 3x drive. But the more I thought about it and the more I though it was a good idea to at least have two. Not only am I used to dial my cadence according to what I need to do (Flat terrain, or climbing up tracks). And I did think about the downshift to climb up an unexpected hill, which happens quite often when you explore new tracks. Those are the reasons I went with a 2x8 speeds bike. Plus... I did the math and I actually have a wider gear ratio range. The bike comes with a cassette and a front drive with a teeth count that both makes the bike faster on the fastest gears, and slower on the slowest gears compared to my old one. All in all. I can't wait for the snow to melt so I can go ride it.

This is why I want a 2 x drivetrain, best of both worlds! I have a 3 x but Id like to not have to actively think about gearing as much

I’m still riding my 20 yr old Trek hard tail 3x8, but now in more of a cross over mode with hybrid tires (unfortunately, I’m no longer in CO). I love the 3x setup because I think of it as 3 modes for the bike. Small ring for climbs, mid ring for neighborhood or flat trails, and large ring for speed. As long as my front gear is in the right mode, the 8 gear cassette in the back gives me all the range of gearsI need for each situation. Then again, I’m also a huge fan of stick shift cars. Now get off my lawn! Lol

As someone who rides with rodies on his mtb every once in a while, the ability of the 3-by drive train to have a bigger gear is also a huge advantage. If you want a really low gear, all you need is a big cassette in the end, but there is an obvious limit to how small the smallest gear on your cassette is. So having a bigger ring up front allows me to have gear that can go 50kph by paddling.

I have a 20 year old GT Avalanche that I've modified for bike packing. Original 42, 32, 22 up front, with a newer 11-46 9 speed on the back. The sheer versatility of that machine is insane. Realistically, I can use four of the gears on the cassette on each front ring to keep the chain line sensible, but regardless of kit I'm lugging or terrain, I'll always have a suitable gear to use.

My bike was converted from 3x8 to 2x8 with a thick bash guard in place of the largest chainring. Gotta say I love that setup, plenty of gear to get up to 45kmh or so on flats, no ninja star, super durable. 👌 I usually cruise trails in 2x3 for 6th gear, and can drop instantly to 3rd for climbs.

The one reason I'm still sticking with a 3X, that is the higher cruise speed on tarmac using the biggest chainring. 36T ring with 11T cassette is still kinda in the chill pace for me.

Running a 44 tooth front ring on an 11 tooth cog with little 26" wheels still goes faster on the road sections than my 1x 29er. That 44 tooth chainring is almost 20 years old too. This is why 90s mountain bikes make great city bikes.

Triple chainring cranks really do help on extreme climbs if you're on the heavier side. I just completed an experiment using trip as to a local hill and the ascent was happier and easier on my Raleigh Max (modified) than my venerable kona cooler. The descent was more fun too but I love the old school. Nothing made me grin like seeing an old Saracen or GT on the repair schedule with a full strip down. Love the channel, thanks to all who make it happen.

I just bought my first MTB and this video was really helpful in understanding the differences and things I would like to do to customize my bike.

One of the things that I like about multi-chainring drivetrains, and the reason I went with a 2x on the gravel bike I bought recently, is because I like the smaller steps between the cassette gears. The wide-range cassettes that are necessary to get the climbing capability for 1x systems just necessitate comparatively giant jumps between gears. The same smaller-jumps-between gears characteristic can be attributed to 3x mountain bikes, although terrain usually changes more dramatically and more quickly when using a MTB as it's designed, which really makes the bigger jumps of 1x systems more helpful. But for rolling terrain where you get slower or more subtle changes in incline, and generally longer, more steady climbs, the smaller jumps between gears make it much easier to fine-tune your cadence to your speed and incline, which makes for more comfortable riding.

Seth’s video title: Why the front derailleur is better for MTB Also Seth: Never rides with a front derailleur

Your channel has really helped me take a second crack at getting into mountain biking, thank you for the content. Taking it more seriously now than I did as an airheaded teen! 😅

I learned 3x9 and i don't feel like i'm missing out on anything. I can get up to good speeds and climb hills like it's nothing. I'm pretty sure my next bike will have the same (or a similar 3x system) because i just love the mechanism.

Love my old 3x9, can climb steep hills and trails even with camping gear on the pannier rack, and race down hills at ridiculous speeds, all on the same bike. My 1x usually gets caught out on steeper climbs and runs out quickly downhill, just doesn't have the range I've been accustomed to and is no where near as reliable

Another advantage is that on older 26" wheel MTB the smaller cassette means a smaller derailleur so it sits higher over the ground and it's therefore safer from rocks

Still rocking my 3X setup on my mountain bike. 22-36-50 with a 9 speed cassette 11-48. Best setup I've ever ridden.

i really love my bicycle's 2x drivetrain, dropping to the smaller chain ring is so fast and easy and it works like a charm. 2x also allows me to go faster compared to a 1x when needed which i really appreciate

I still run a hardtail with 3x front set. I love it, climbing can be so easy when shifting all the way down. I even went up some slopes that a dude with a full suspension EMTB had to walk up, which was just to get to the downhill section.

I own several bikes with a 3x7 set-up, and for me the biggest advantage is cost. A 7 speed chain costs a quarter of the price of an 11 speed chain, and lasts 10,000 miles instead of 2,000 miles. In other words, the 11 speed bike chain costs 20 times more per mile. It's a similar situation with rings and cassettes - 1x systems cost much more per mile. Which is probably why the bike industry loves 1x systems, because they can sell more expensive parts, far more frequently. For the bike industry, 1x systems are the goose that lays the golden egg.

I have to admit that I used to extol the virtues of a 3x set up with its huge range of road and mtb gear ratios. However, having taken up mountain biking more seriously the wide ratio 1x10/12 speed is so much simpler to use. I’ve never had a 3x set up that changes down effortlessly under load which puts it at a great disadvantage for sudden climbs. This makes it needlessly complex system to use. I’ve recently purchased an entry level gravel bike with a wide ratio 1x10 set up. I love it.

Honestly I love my 3x MTB for the big chainring that lets me go fast on-roads, as opposed to full-time gunning a small chainring off road and on roads

I agree with this. When I bought a cyclocross bike about 15 years ago I replaced the 2x10 with a 3x10. It makes the bike much more versatile, from fast road riding to loaded touring to trail riding. I'm now 72 and need those lower gears.

Perhaps I missed it in the video, but for me one of the best features of a 2x or 3x system is cadence. The rear cassette, with its smaller steps between gears, allows me to maintain a certain rhythm and cadence even when I cycle through the gears. I don’t have as extreme steps between gears as with a 1x. The 2x and 3x offer a wider range of gearing, as well. Funny how mass marketing has new buyers believing 1x is the way to go - you avoid dropped chains, etc. Most folks I see out on the trails are over-biked - and I'm one of those folks - and a bike with a front derailleur might be a better choice for them. Many people ride pretty mild trails and gravel or fire roads, and a 2X or 3X bike would be great for them. Extra weight? The 1X requires a heavier cassette to even close to the gear range offered by a 2X or 3X system. Yep, going 1X - no front derailleur, only one front chainring, and no shifter, but we're maybe talking a pound. I have a Cannondale Flash 3, with a 2x10 system, and the bike, stock, weighs just over 26 pounds. With no efforts at reducing its weight. That's light enough for me. To me, the advantages of the 1x is simplicity and freeing up valuable real estate on the handlebar to mount extra goodies, like a dropper post lever. For me, particularly on my cross country bike, cadence is king, so I prefer a 2x or 3x drivetrain. My 62 year old legs prefers that 2X system, as well.

Nice to finally see someone with some sense. For the past decade I've gotten the best of both worlds by running a 2x10 drive train with an extra wide range between the two chainrings. I use a 42-tooth big ring, which functions as a 1x drive train most of the time, and a 26-tooth small ring (yes, the front derailleur can handle that gap) that lets me downshift-dump into granny gear with a single click. I can climb any hill that my tires can maintain traction on, even if I'm taken by surprise.

My Trek 4900 is rocking a 3x10 setup and I utilize the speed and climbing ability my 3x setup provides since I mostly ride light cross country I end up biking on roads most of the time and the speed it gives me is certainly handy.

I personally love my 3 by 8!! I use my bike both for riding around town and on trails, and I love the range that the 3bys offer. Plus I really don't mind shifting more.

i love the ease of dropping to a smaller chain in the front

I really love the 3x10 on my bike! A lot of small steps to adjust to any riding condition.

I have 7 year old 3x9 Trek XCaliber and as I got into bikes and everything that comes with them I have learnet about 1x drivetrains. They all look super cool and pro to me with possible ease of use and maintanence with the simplicity. Few times I have considered converting my bike into a 1x but 3x comes in handy a lot. When on the trails I use the 2nd gear normally and if things get steep, I switch to easy mode with the 1st gear instantly, when riding on roads or in the streets 2nd gear is really useful, it is both comfortable to pedal and gives enough speed to keep up with the cars in slower traffic. When there are no cars I just switch to 3rd go fast. But tbh I only consider using the full range at the rear when I am at the 2nd gear, I don't tend to go close to 9th when I am at the 1st in front, or closer to 1st when I am on 3rd. 3x really helps me since I drive all types of terrain but if I was getting a new bike I would have gone for a 1x for tackling the trails. It is a confusing debate, I forgot what to write while writing this comment.

I remember racing on a 3x7. On sharp turns, or when a sudden stop is needed, we drop from the big ring to the middle ring, for a faster acceleration. Same thing with with traffic lights, just shifting the FD down makes it a whole lighter to start again.

I’m so glad he talked about this because everyone just goes with the next new thing and just says it’s better.

Damn, this video was perfect! I hardly comment on videos, but this one covered so much and answered so many of my questions. Man thank you for taking the time to make this, subscribed for sure.

I just loved my mega9 XT drivetrain, shifted fast, and the change to the granny going uphill was so satisfying

I’m not sure about that “chain retention” point though. My chain was constantly falling off my 3x setup and has never fallen off my 1x

Dropping down to a way lower gear by shifting the front gear is one of the main reasons for me to like my 3x9. Its very convenient. Also having the casette gears being closer together in numbers makes less big steps between the gears which is quite comfortable at longer tours.

You ansewered exactly the questions I had. Really enjoying your channel. Thanks, Seth.

I have 2x11 and when 1x11 was a thing, i chose Di2 and I'm very happy with my choice. I have a lower Oval chain ring and a Drop Stop up top. Had to CNC for it all to fit, but worked very well!

For me the 2x is perfect. Gives me all the range I could ever want, enables me to use less expensive cassettes and derailleurs and is still easy to operate and not too heavy.

The best thing is waking up and there being a brand new Seth video

On my old DH bike I ran it 1x9 and I used on old front derailleur as a chain guide and it worked surprisingly well.

I think a lot of the hate comes from the fact that a lot of bikes aren’t tuned perfectly and the issues are more noticeable with two derailleurs. Tuned right and used right, 3x is great.

What about 2x higher end drivetrains? Do they still exist? Shimano XT or SRAM X7.

Seth, thoughtful content as usual. Thanks! My new Enduro bike is a 1X12, but my last trail bike was 2X10, and I do miss it sometimes when going in and out of climbing mode. XTR 2X systems are awesome. Cheers.

As someone who primarily rides in neighborhoods (I envy your awesome forests) I find the 3by useful just to have a much wider jump available for stopping and starting and jumping through dirt or rocks and junk. It means I can quickly have cruise/start/climb available and then fine tune with the rear.

The biggest advantage of a 3x drivetrain is missing: With the same range, you have smaller gear jumps. This is quite important if you also ride longer distances on flat roads and the cadence should fit. It is annoying when I can not find a suitable gear because the gaps are too large.

Congratulations for being brave enough to acknowledge that the 3X drivetrain can still do a good job. I'm sure you will cop a lot of flak for daring to speak up and making such valid points. You have taken a very balanced view which unfortunately is lacking in so many videos out there that claim everything that's not "the newest & best" must be crap. I still often choose my old 2012 Giant X1 26er (dual suspension) with 3X up front for the really tight mountainous single tracks - lots of fun, climbs well, really nimble. No complaints.

When I was bicycling everyday to commute to work doing interior remodeling...and going up and over bridges...with my trailer loaded down with a miter saw, table saw, and materials...my Campy 3x was THE necessary component! Then, when I was unhooked and blowing around on the weekends, the large chainring was the only one I needed...perfect versatility!

I run 3x9, 3x10, 2x10 and 1x12 and love them all for various reasons. 3x10 on the touring rig with barend shifters is my favorite but they're all good at different things 🙂

I really love 2x since you can really go to an even heavier or easier gear in a second. Really useful for commutes and steep hills so you don't stall trying to shift gears uphills and quickly accelerate on level surfaces.

I was really wanting someone explains this reality on KZfaq and you did. I use a 3by on my XC bike and the quick dropping is so helpful on a new trail when I don't know when a steep part is coming. Thanks! Cheers!

Awesome, I love my 3x, I like the chain being straight and not torqued to the side, love the dropping front chainring on hills, and they totally last longer!

Good vid...I was a bit embarrassed to bring my 3x in to be serviced, but I feel better now, armed with this knowledge 👍🏻

I love how Oscar bits Seth's foot every time Seth gos for a ride

Ohhh, here we go.... (Nah, I'm sure some people will be up-in-arms on this though.) Honestly I ran 3x until about last season. They really do have their place; really depends on the riding you do; and how you use your gears. On the trail though; I don't think 90% of riders have the actual mechanical sympathy to actually utilize them effectively.

What a great explainer video. You sir, are an excellent communicator and media maven! Thank you!

I also like having 3x front derailleur because I LOVE shifting gears on my bike. It gives me opportunity to simply do something more during my rides and have fun with the bike

Never before I had heard so many good considerations about three frontal gears! I agree completely with all them. About more possibilities of relations between cogs, about more durability on front gears, less use of them, better alignment of chain, less annoying noises... Perfect and wise words! Thanks!

So…this is Seth justifying why it’s okay to leave the three-bys on his next flips! He could have just said it isn’t worth swapping out the drive-train on an old, yet still reliable bike! 😆 Parts bin must be running low on one-by drive train parts. I have been questioning the one-by conversions on those recent flips.

I’ve got a 2007 Specailized Enduro FSR. I rebuilt it earlier this year from the ground up. Down to the paint (your flip bike series helped give me the confidence to do it). I changed from a 3 x 9 to a 1 x 12 after my 3 x 9 rear derailleur got cleave off (rest was pretty knackered also). I love my 1 x 12. Easier to maintain, great uphill and down. Wouldn’t have it any other way. My bike is older and heavier I’m never going to win races on it but damn I love it.

I have no idea why I started watching your videos, never been into bicycles, I'm into motorcycles, but I absolutely enjoy watching your videos.

This is kind of making the case for wearing a Pocket/Protector organizer from a practicality perspective. Oh, was 3:39 a pause for thought?

3x are also great for people who ride their bike on and off road. Especially for beginners, they offer a low enough gear for climbing offroad hills and a redicilous high gear for bombing tarmac descends

A really good explanation. Great visuals to aid the explanation. Thanks much!

This is one of your best videos. Very informative.

My xc bike is still a 2x and I wouldn't give that up. My trail bike is 1x though, and it's fine-ish. But the range and versatility of 2x is fantastic.

I like the simplicity of a 1x drivetrain, though I never really had the issues with a 3x that many people seem to have had.

I have a 3x8 drivetrain on my 2013 Mongoose Switchback Expert. The crankset is a SR Suntour XCC alloy 3x 42-34-24 tooth crankset. The rear cassette was originally a Sunrace CSM66-AU 11-32T 8 speed cassette which I upgraded to a Sunrace CSM680 11-40T 8 speed casette. I mainly use the 34T front chainring when I am riding and the 24T front chainring for going up hills. I like having the 3x8 setup.

Thoroughly enjoyable explanations. Thanks a lot

I'd also add that the lower number of gears on the cassette of a 3x make it much easier to get the rear derailleur shifting properly. With a 12 speed, a little bump to the derailleur can throw things completely out of whack, whereas with an 8 speed, you have a lot more room for error.

I think that 2x drivetrains are a good mix. I have deore 2x10 on my MTB and even if I use 90% of the time the bigger chainring. Sometimes I need to drop to the smaller one and it’s nice to have it available.

The Alivio trekking triple with a 26-36-48 paired with an 11-32 cassette is my favorite all around setup. I use it on my 2 most ridden hybrid bikes. I can tackle logging roads, city rides, load up my 2 kids and tow them anywhere all with either one. Nice close ratios and a huge range. I tried a 1x10 on my mtb and went back to a 2x10 with a 22-36 front paired with an 11-36 cassette.

I have 3x10 on my hybrid bike and im pleased with it. I use the biggest front gear on the road, the smallest in forest, field and the middle one is all around useful. But when I will need to replace parts I will got with 3x9 to have thicker chain and longer lasting parts, also 3x10 is hard to adjust to have smallest/biggest gears available from the middle front gear.

Another advantage of the 1X is increased ground clearance when going over large drops. That's the main reason I can't see myself going back to 2/3X

3x8 seems perfect for durability, chainline angle, and price. I never had interest in 9-speed "upgrades" because the required narrower chains were more expensive than the good old 5, 6, 7, and 8 speed chains.

Cool video 😁 it was fun to watch, as I am an old school mountain biker..and love my 26"..but still the ease of 1x appeal to me. Very good, valid points on the 3x systems 👍👌 you earned another subscriber 😀

I still ride my fathers old raleigh from the late 90’s early 00’s. I used in college and still take it on trails. That bike has seen 4 major crashes and 1 flash flood and it STILL keeps going. Replaced the cassette rear derailleur and cable but the front is all original and still runs as if it was fresh from the factory.

Seth raises several very interesting points. I love these educational videos

With 2 or 3 gears on front, we have a lot of range for speeding or climbing. That is useful to ride the same bike under different conditions.

I'm still using 3by my old setup is 3x7 and now I'm using 3x9 it's still my fav setup 👍 planning to change big chainring to 44t for more speed at flat road

That very good tech information . Like the motobike , people try to change the bigger chain for offroad but on the bike they try to change to more cassete and thinner chain

I guess I'm in the curmudgeon category. Earlier this year, I built up a brand new Surly Bridge Club and purposely did a 3x9, friction shifter setup. I wanted reliability and simplicity. And I remember thinking, "Well, that's the way I built my bikes 25 years ago. It's still good for today." Ha! Great video!

7:34 "...to explain why 29 gears are better..." That would be a huge cassette 😂😂😂 Too good of a video, listed points I've never thought about!

My first mountain bike was a Trek 4300 bought in 2004. Never owning a bike with gears the shop owner was very helpful in explaining how to fit on the bike and how to shift. With a 24 speed he said, the first chainring will be for gears 1, 2, 3 and maybe 4. From gears 4, 5 and 6 you'll want to go up to the second chain ring. From 6, 7 and 8 you'll want to go up to the third chain ring. Most of the time you'll stay within gears 4, 5 and 6 and the second chainring. Obviously I'm overlapping some but I've never had issues doing this. That being said I broke my front derailleur cable twice and when they changed out the front derailleur all together I could never get all the rubbing out of being in certain gears. Now that I've passed the Trek on to my son I'm fixing to change out the cassette from an 11 to 32, to a 11 to 34 and get rid of the front derailleur and put a 34 tooth chain ring which is the middle chainring on the original set up. I completely agree though, I loved the years with my 3x drivetrain but now all my bikes are 1x and gearing the back for my needs is much simpler and way less troublesome.

great video! some months ago i was thinking in "upgrading" to 1x but the fact of changing quickly gears made me decide to keep my old 2011 system 3x9. i use the bike for commuting so, sometimes find a stop light / pedestrian / car, that make me reduce speed suddenly. this would be annoying with a 1x. one more reason to those you mentioned, is that a x11 or x12 cassette, creates a big torque in the rear hub, causing one more source of faster wearing out (or one more source for expensive materials).

You missed a couple: 1/ The wider range of gears. Particularly at the high/fast end. If your mountain biking consists entirely of climbing steep hills (only low gears required) and flying down fast downhills (no pedalling required at all) then you wouldn't appreciate this. But if you also do occasional flattish easy trails, and prefer a low cadence, one ring designs just aren't anywhere near big enough, even with the smallest number of teeth at the back, you're still pedalling way faster than you need to. This is where the marketing of more gears is actually kind of relevant, yes there are some you can't use, but the range between your highest gear and lowest gear is broader. 2/ Those really small gears on the back, all the stress is distributed over a small number of teeth, so they tend to skip and damage really easily. By having a bigger gear at the front, the ones at the back don't need so few teeth so don't skip under hard pedalling, and don't damage / wear out so easily (especially if you pedal hard in higher gears a lot).

I’ve been riding 3x all my life. I like having the options. Middle ring and middle of cassette for flats and small climbs, big ring and small cogs on the cassette for downhill and going fast on flats, small ring and end of cassette for climbs for little effort with low gears equivalent to the best 1x systems. It covers everything. They are super cheap and durable, and parts are super cheap. Front Derailer really does act as a Chen retention mechanism. If it pops off the ring you’re on you just push the shifter up a bit and pedal and it pops right back on. I like Shimano 9 and 8 speed alivio. Super great value for 3x. Great value. Super durable, super cheap. I’ve been thinking about going to a gravel bike with 2x but 3x will still hold a soft spot in my heart. I remember I got to the top of climb and this old dude on a fancy road bike said, “ your made it up here on that pos” and I said, “yeah, and I’m about to go further than you”. I will say however that parts for 3x are getting less common. My cassette wore out recently and I called around local shops to see if they had it in stock and nobody carried anything less than 10 speed. I had to order online and do it myself with some tools from my universities bike stations. The cassette was still cheap online and I didn’t have to pay anything to get installed because I did it myself. Really my biggest complaint with 3x is the Shimano octalink bb which has eventually started to creek like crazy under a lot of power after a couple of years, otherwise they are great.

The thing I miss most is related to what you said about the grinding on punchy climbs, but different. It’s the speed a single shift to go from descending to climbing, compared to the sheer number of clicks to move my 1x between modes. But the simplicity, weight, and simpler cockpit are pretty huge wins.

Curmudge-ON! Before rear suspension entered my life, ,my most fond bicycle transmission has been the Shimano 8 speed internal gear hub-which I failed to kill in the rocky mountains....I spent a lot of time sourcing a double chainring crank set for my boost 2x10, and I’m grateful for Origin8 for making sensible products. It’s freaking great to ride rigid mountain drop 29x3” anywhere, and still pedal at 20MPH. 24/38 x 11/36.

When I was living in Indonesia I saw a lot of 2x11 bikes. They had a main gear used most of the time, and a smaller gear for climbing steep slopes. Something they had a lot off! What I was told is that people preferred a second gear up front so they can just drop into a lower gear to climb a hill then jump back up into normal riding
