    What gearing are you running?

    The stock gearing on my new 2008 San Jose (my first SS) is 42/17 and I find I spin out way too frequently. Minneapolis isn't too hilly but it's not totally flat. I ordered a 46T chain ring...am I insane? My favorite combo on my Rockhopper is 42/12 so I think I made the right choice (haven't calculated anything). What do you think? What do you ride?

    42:17... 46:17... Are you even going off road or up a hill? Sounds like you are riding pavement at a guess.

    I run 32:16 on a 29er offroad but this is a seriously hilly area. I ran 42:17 on my SS road bike in the same area. Not many people are running 42 or 46 up front off road unless it's dead flat.

    On my local trails Im riding a 32:20 on a 29er and rarely over spin but its a rocky, techy terrain with very little flats. Im considering going to a 19T cog now as my strength is gaining.

    On a geared HT I visit the granny gear a couple of times on these same trails and find myselt frequently riding in a 32:32 gearing on the climbs.

    32:18 on a 29er. I live in western PA so there are hills a plenty. Good gearing with the exception of a really steep long hill. Then I'm running.

    32:18 for now. It was great for 5 hours at Burke VT. Hope to get stronger legs for next year. Would like to run 32:17 or 32:16 for local races. My road SS is 42:16.

    Cheers,

    I use 44:18 off road and flip the wheel for 44:16 on road. This is on my SJ, 32:16 and 32:17 are what I use on my mtb's here in norcal.

    32x18 on a 26er almost every where. We have lots of long climbs and steep descents so I just coast down with no pedaling. I find this to be a great gear to haul ass up hills without working really hard to turn the cranks over each time. This is what I used to do the Kirkwood 8 hour race and I was pulling faster times than the fastest geared guys. I use 32x17 when I am not going to be in the saddle all day and the climbing isn't too long.

    Bonking ... not feelin' well

    My SJ will be used on the pavement only as my commuter and run about. Based on the responses I think I'm making the right decision but I guess I'll just have to wait until next week to find out.
    I haven't converted to SS yet on the RockHopper but let me tell you that the SRAM X.9 s**t (front & rear der, trigger shifters, 980 cassette, chain) that I just bought and installed is going to push me there a lot quicker than if I would have if I stayed with Shimano. I'm not too impressed with the X.9 line .

    Currently 36:20 on a 29er. I have been mostly on 32:20 before that

    EDIT: 36:16 as my road gear

    Okay... the OP is looking for info on road commuter ratios, not off-road mtb ratios. 10000 lakes, what tires will you be running? I would say 46/17 is pretty good if you're running some narrow slicks. Might want to keep that 42 ring for when winter comes back though.

    I run 40/15 on my fixed commuter. Can't go much higher than that b/c of hills, and the wind that blows out of the SW 75% of the year.

    Thanks Sunset -
    I'm currently running the stock WTB Terrainasuarus 700x32 but will be picking up this weekend two Continental Gator Skins 700x28. For the first time ever, today I've been crunching gear ratio numbers and I think my LBS sold me the right chain ring at 46T (thanks PennCycle). Although I'm having a hell of a time locating a 46T bash guard...not that I need one for road riding but they look cool and when winter comes will help keep my pant leg out of the chain.

    My 29re came with 33:20, but I've been trying out 33:18 lately and I think I'll stick with that.

    Very nice tires. I run the 25s because of frame clearance issues. AFAIK, one of the best choices for commuting on the market.

    For a bashring, just take any old el-cheapo 48T and grind the teeth off. You might also check with the cyclocross guys for other options.

    I ride 32-14 most of the time, which is normally when I'm riding around town. If I'm on trails I either stick with 32-14 or 32-16.

    Do you guys swap your cogs out very often? Seems like pretty big pain in the ass to me.

    I keep the 14 cog on all of the time unless I know I'm doing on a trail which isn't as outstretched and more hilly.

    It's honestly very easy.

    Pop wheel off. Take off lockring, new cog, lock down, put wheel on.

    For me, it's very easy because I have vertical dropouts so I don't have to worry about my rear brake being offset. I just slap the tensioner on and presto, good to go. It's really not a pain to me at all.

    Im impressed to see many of you guys running as much as 58 gear inches on your 29er's in the bush!....madness.

    I havent met anyone yet running more than 52 around here. You guys are super strong thats for sure.

    I have track ends, and I had to break my chain and add a half link just to get it to work right, only going from 20T to 18T.
    I guess the tensioners give you a lot more play.
