    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.

    Lotsa hilly stuff here.
    I climb somewhere between 10K & 20K feet each month at between 75 & 200 miles per month.

    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...
