    26" 33/16 I like pointing down rather than pointing up. This gearing can climb and is good on the flats but it spins out a bit when flying DH. I don't mind coasting in those sections though. Where are all the pics?

    32x22 on my 29er, and I'm fine with it. Any fellow Clydesdale that rides the rocky stuff here in the northern NM mountains will understand.

    Gearings? What trail? Did it rain? How do I feel? Is a training ride or a race?

    I change it accordingly. 32t & 33t for the front. 15 thru 22t for the rear.
    Authorities speculate that speed may have been a factor. They are also holding gravity and inertia for questioning.

    On the 29'er I run a 51.5" gear (32x18)
    and on the "wee bike" I run a 53" gear (32x16 with LARGE VOLUME tires).

    32x18 most of the time on the 26(sometimes 34x18)
    32x20 so far on the 29er. Might go up to 32x19 though.

    32/20 on the 29'er for typical ups & downs in sloppy winter conditions, and 34/22 on 26" wheels to work a mile-long climbing problem that averages 10%. I'm 51 and I get waay too many empty calories from beer this time of year.
    Also, the streets are full of horizontal dropouts...

    Currently 34x20/29er/175 cranks. But. Even tho its steep where I ride, I'm noticing that its getting too easy once I stand up - so I've got a 19t on order. I started out with 34x22 about a year+ ago and still changing.

    I run different gears for the things that I'll do and oh the places I'll go.



    Anywhere between 32X18 to 32X20 on my MTB or 36X19 to 36X15 on my skinny tired fixie off road boredom killer.

    Trying 32X17 in the NC mountains with my new bolt-on fixed gear Tomi cog today.

    42x15/170 cranks on the skinny-tire fixed.

    34x18--26x2.4 /180 cranks on my main squeeze.

    that's currently, but have 15,16,17 ready to go.

    Gear-inches vary quite a bit by tire size (inside a rim size) and I'm running the bigguns.

    Just curious, why do you run spacers, your stem flipped, and a riser bar?
    It's kind of like going up, then down, then up.
    Couldn't you get the same position without the spacers, or less of them, and the stem flipped over?

    My gear ratio is always the wrong one.

    But 32:18 on a 26er seems to be less wrong than others in the places where I ride and race.

    26in Fixie, 34:16 is good balance between having some torque available and not spinning out at 10mph.

    33 x 20 on my 29'er (about a 48 inch gear with the tires I have) I like to climb, and this allows me to get up just about everything. If it's really long and steep, I usually have to take a "pulse stop" or three, but have climbed as steep as 20+% for about 1/2 mile on it. It's a nice gear for things like riding up Mt Tam and "how hard" just depends on how fast I want to try to keep the pedals turning. Took it easy today with a couple of friends and was able to talk the entire way up. 15 mph or so is about as fast as I can ride and keep the pedals turning for any time though. If it's flatter where you ride you might want taller, if it is steep and rocky, go low. I'm not racing, just trail riding and having a blast on my SS.
    Calculate your gear by dividing the rear cog teeth into the front ring teeth and multiplying by the wheel diameter. (i.e.: 33 / 20 = 1.65, x 28.8" = 47.5" gear) Estimate 29" for most fatter (2.3 or 2.4") tires and about 28.5" for smaller (2.0 - 2.1") tires. Calculate the gear you have now, and if you want it harder or easier see what a tooth or two will do in the calculator. A 10% change can be huge, unless you are way too tall or too low already.

    That picture was right after I had finished building it, before I did any fine-tuning (hydro hose shortening, chain alignment, stem spacers). I ended up dropping the stem (kept the negative rise) and putting the spacers on top. The Juan has a short headtube, and if I'd cut the steerer to fit, the fork would be almost unuseable on anything but the smaller medium/small bikes. I have a tendency to swap forks/frames a lot, so I always try to leave myself with some cushion in that regard.

    Just switched

    I recently switched from 32-16 to a 34-18. On flattish/rolling singletrack it is about the same, but I have a higher success ratio on climbs with technical features (logs, roots, rocks and steps).

    I don't think I would go any higher (on the rear cog) unless I am going to do a major climb (1,000 ft or more). Most of my climbs are topping out in the 100-200 ft range.

    My Choice...

    ..is to run 32x20 for Bootleg Canyon, and 32x18 for 24hrs of Old Pueblo. This is on a 29er rigid Rig.

    Dos Niner free at 32:19, maybe 18.
    will fix her at 32:18 or 17 probably.

    And yeah, Rich got a pair of proto cogs,
    along with the CellerRat and local Cupcakes.

    SS Outlaw got the first few of the first small

    Run my 26" Unit at 34-18, for undulating hills, not flat at all, not serious long climbing either.

    Funny, but to me it sounds like some of these guys ride very flat terrain (and we all know the "rolling hills" is code word for flat).

    JimmyNY, just stick with it a while. You'll get stronger. I have a 33 x 20 on my 29'er here in the Bay Area hills. I have run it taller (33 x 18) and went back to the 20t for the few little super-steep sections. Every gear has it's perfect spot, and every gear is a compromise, unless you live where it is flat, smooth-surfaced and the wind never blows...

    currently at 34 x 16 (26") but I just ordered a 17t for the rear. I think that will probably be a better over all gearing for me and the trails I ride.

    34/19 on 26". There are no flats here. It's all either (at least subtly) uphill or downhill.

    29" came with a 32x20 but I swapped it out for an 18. Tried the 20 the other day just to "remember" and it was way too easy for the low altitude climbing here in the Midwest (or Middle East as I like to call it). Back to the 18.

    probably true, where im riding im MD (schaeffer farms) it's pretty flat with just a few climbs but nothing long.

    i got a question about gearing..the frame is not for single speed and i want to get rid of my tensioner..currently my gear is 34/16 i took the tensioner off got a half link thinking this would work but if i take one link out its wayy wayy to tight and if i leave it the way it is now its toooo loose..question is if i went to a 17 or 18 tooth cog would this take up enough slack to tighten the chain...i called a few bike stores in richmond this morning only one guy knew anything about single speed and he said that most likely it wont work but a slight possiblility it would..so basically would this work if i got a bigger cog? if so what cog's shuld i get ive been riding surly...any suggestions?

    I started with a cheapo SS kit which I found a bit noisy. There is a magic gear calculator that I used. It might work but you may not get the exact gear in inches you want. I wanted 70 gear inch but the magic gear (without tensioner) given was 64. If you could give me the length of your chainstay measuring from the center of bottom bracket to center of dropout, we can try. An example is a Merlin mountain's chainstay length is 16.75 inches.

    32 X 16 on a 26" if I want to hurt on most trails (but get stronger). Normally 32 X 18 works just about anywhere I ride in NC.
    Homebrew is the only way to go.

    29er 32x22.

    I'm a clyde (well, fat really), and new to SS. SF bay area is fairly hilly, and the 32x20 was a bit to tall for me on the hills, initially. I have a 21 which I'll be putting on soon. Maybe someday, back to the 20.

    Variable SS

    Was running 29er at 34x19, but slacked off and had to go back to 34x20. And then I picked up an Inbred frame to try out - built up out of spare parts, and swapping wheels between that and the Karate Monkey.

    The point? I run RotoR cranks on the KM, and the parts bin yielded some RaceFace cranks for the inbred. 34t rings on both, 175mm arms on both, but Man! what a difference. I had ridden the RotoRs vs my 3x9 FS and thought "nice on a SS, but I wouldn't change the FS cranks".

    SO - I looked for info and found this pic of equivalent size vs position for a Rotor with 34t (lucky me). So I'm pushing a 38x20, but if I'm pulling up on the backstroke it's a 30x20. This explains why I'm loving pulling up when climbing

    Why doesn't anyone run a 30 in the front?

    1. I am thinking about trying a 30 X 18...will it work?

    2. I am concerned about chain slap that I already have at 30 X 16...

    26" 32x18 - PERFECT for all around riding. Urban up hills mashing around campus or droppin psi's on the holy rollers and hittin the trails in santa cruz. Does spin out on flats when trying to hang with the 700cc crew.

    29" 32x16 - hanging with the fixed gear road bike friends is fun, but whats up with the hills absolutely killin' my legs!!!! On long night rides in the city, bad news. Only good for flats. Will 30 x 16 be better?

    Generally 32x17 on a 29+ but largely depends on the terrain I'm riding in.

    I'll be doing a race in 2 weeks time on 32x20 with normal 29" tyres with 3000m climbing over 120km's.

    The best gear is 32x20x29in. You're welcome!

    jk, jk....sometimes I like to pick the gear for terrain, other times I like to set and forget it!

    For shorter rides and races, taller gearing is tempting, but for everyday rides and races over 30 miles, I say gear down, save your matches, and settle in for a good consistent pace.
    At what point did you decide you needed more than 1 gear?

    Trying out 32x22 29er for now. It's pretty nice to able to stay seated over more terrain and stand with a higher cadence.

    with time, i tend to gear up but have settled on:

    dirt, 26: 34x19

    road, 700: 44x16 (cruising, all purpose), 36x24 (long, steep climbing)

    Post your gear ratio!!!

    32x20 in the hilly SF Bay Area. I've also used 32x21 to get up some steep hills. I've tried 32x22, but it was too spinny.

    29er running 32x18. Perfect all round gear I use from in town 500 vert in 10 miles to 1700+ in under 4. But the latter does suck and 32x18 would be better.

    Kinda funny how spam revived an old thread.

    I run 32x18 on my On One Scandal. I am relatively new to SS and haven't tried any other combos. Seems to be perfect for the Phoenix area riding I do.

    29 inch HT. Started with 32x20 on trails and then switched to 32x17. Began to ride a lot of gravel, so just went to 34x15, going to ride this on the trainer this winter too.

    Looking for a stainless steel chainring in 32t for a complete ring, cog, and chain setup in 32x18 to use on the trails this spring. Till I can afford another bike.

    On One doesn't show a stainless 32t on their site. Who else has one, I don't like the looks of the Surly.

    32-21, in Colorado Mountains. Lots of extended standing climbing. I'm thinking of dropping to 32-22 so I dont have to mash as hard. 29" high volume tires of course.

    I run a 32 x 16 for most everything on the trail and racing. A 32 x 15 on my practice loop for conditioning. Pretty flat with no big grades. I am on a trek rig 29r for three years now.

    I am building air 9 carbon this winter. How will my gear ratio change, if any, with the EBB?

    32x19. I have considered dropping down to an 18 but the 19 suits most of my trails really well, which range from stupid tech to flowy New England trails with lots of climbing. I am happy with it, it works and I can go all day with that ratio. fully rigid 29er (in the winter) Suspended in the non snowy months.

    Your gear ratio will not change just because you use an EBB. That is only a chain tensioning mechanism.

    I ended my season with 36x18, to lazy to bother with the trainer this winter and gonna start off next spring with the same 36x18 which will subsequently kill me for the first few weeks! It'll be worth it after the initial pain and adjustment period, that I go through every spring. But I really love the speed I can get in the flats and at the start of descents! FWIW, this will be the first time I start the season on SS...

    My 29er runs a 32x21. Maybe not ideal for all, but works great for me!

    32 x 19 or 20 or 21 or 22 - depends where I'm riding. Mostly 32x20 though. (on a 29er)

    32x20 as that's what came on my Crave. I've only got one ride on it so far but figure I may look to change it up this summer after I get more miles on it.

    On my 1/2 fat 26er winter mode 34*22 but I may switch it up to a 32*23. In the summer full ridged 26" I used to keep it at 34*18 but looking at 32*20 for this summer when I make it a 69er.

    There's lot's of varied terrain in PHX and kinda depends what you ride and how long you go out for. For <3hrs at places like PMP, Sonoran, the flatter McD stuff, Browns Ranch, BCT, etc, I roll a 32x18. But if I do the passes in the McD's (Windgate, Bell, Sunrise), or long climbfests out on the Arizona Trail south of Picket Post, 32x20 can even be tough at times. When the bikepacking gear goes on the bike, 32x20 or 21 is usually the ticket. I rode the long course at the Santa Fe Big Friggen Loop last summer (72 miles, 14500 vft) with a 32x22 and wished I had a 23t.

    Just switched to 32/21 for some winter climbing training. Just kept losing momentum and getting stuck/stopped on some of the nastier climbs.

    29er. Was running 32-20 and wanted to make the jump and went 32-18. It's too much for me right now in Phx. I'm going to 30-18 next week which should put me in between the other two I believe.

    I've been on a few rides with my 32-18 and I'm considering switching to 32-17. Maybe I can find a 17 on Craigslist.

    32x18, 29er. I might try a 17 or 16 cog this season as I've started to ride longer distances and more flats (doing more adventure/touring cycling). *gulp* Might even try going geared. :P

    32x19t all up here in Tahoe. I don't walk or else I I would throw on my 18t free wheel. This is on a 29er.

    i just switched from 32:19 to 30:17 on my 29er. I thought it would be about the same gain but the 30:17 somehow is the same as a 32:18 when I use Sheldon Browns ration calculator. I wanted to push a slightly tougher gear this year anyways.

    I have always run 38/22 (for about 7 years) on a rigid 29er; ratio = 1.74. I am building a new rigid SS and wanted to go to a smaller ring on the front for clearance. I run a freewheel on my bike and just sprang for a White Industries on my new build so I wanted to make sure that I made the right choice for rear teeth and would maybe adjust front chainring teeth to change ratio depending on terrain. I was calculating ratios (because wheels & tires were staying the same) and saw that changing the rear tooth count had a more significant effect on ratio than changing the front tooth count. I finally settled on a 19t rear freewheel and, as you see in the graph below, for every tooth I change the front chainring by, the ratio changes by the same amount (0.05 in this case); this is a linear curve. The change in ratio per front tooth will increase slightly on a smaller rear cog and decrease for cogs greater than 19t.



    However, adjusting the rear cog does not have the same amount of change on your gear ratio for each tooth you add or subtract because the curve is inversely exponential, as you see in the graph below. I found this interesting because most people adjust gear ratio with their rear cog (mostly to save money because the have a free-hub and rear cogs are cheaper than front rings [not necessarily the case for those of us running White Ind. freewheel in the rear]).



    To take this one step further, for those of you who would adjust gear ratio by the number of teeth on your rear cog, if you know the gear ratio you want number of teeth on your front ring, you can solve for your rear cog with the following equation (assuming wheel diameter and terrain are fixed):

    [rear cog t] = 1 / ( [ratio] / [fr chainring t] )

    I thought this all was pretty interesting and maybe you do too, if not you probably stopped reading already. I am NOT a mathematician but I do enjoy finding trends in numbers. Some of you out there who are much smarter than me may well find errors in what I have presented, or just thought this is intuitive and boring. Many on here have experimented with lots of combinations and just know what works for their preferred cadence, setup and local terrain. This would be more for the people, like myself, who have an idea what ratio works well but are interested in changing teeth up for one reason or another. Thanks

    I am going to run 32/19 on my next build but will get a 34 tooth front ring for a taller ratio when I want it.

    Currently 32/20...too high on flats/rolling terrain. Going to 32/17, cause I like being mean to myself
    I'm having more FUN than anybody!

    34/19 on a Salsa El Mar 29er in Central Pennsylvania. Rocky, rooty, hilly but not deadly climby. That is a tough combo though and I may have to drop to 34/20 for some races/rides.
