    Single speed guys chime in on gear inches

    How many gear inches are you guys rolling, and for what terrain?
    I know 70 is a good number for an all around road bike, but I've never heard of a general rule for a MTB. In our shop we have one bike rolling 57gi with a suspension fork and another bike rolling 46gi with a rigid carbon fork. Just wondering what other people are having good luck with.
    Thanks.

    I'm in Kansas and ride a variety of trails as well as gravel roads. For the easy stuff I'm running 32/17 which is about 54 g.i. Probably step this up later this year. Everything else I ride 32/20 which is 46 g.i. cause I like to clear eveything possible.

    Who cares what your bike weighs, just ride it!

    Depending on the terrain, I run 32x16, 32x18 or 32x20. cogs are cheap.
    I'm sure when you were getting to the point of blowing nothing was obvious but making the pain stop...I don't know about you but after the fact I always look back at those moments and think 'why didn't I just keep going' but at the time there wasn't enough oxygen on the planet to make me take one more pedal stroke.

    I run a 33X19 on my 29er. On my old 26er it was 32X16.

    In hillier places I swap out to a 33X20 or 21.

    I've been experimenting with the low 60gi range for flat urban terrain (road/grass/gravel)

    2:1 chainring:cog is an excellent starting point for 26" wheels. Adjust as needed.
