    NOOB single speed gearing selection question.

    COGs are cheap but I thought I would ask you old SS Jedi for some advice.

    I've been riding my 29# geared 29er Rockhopper fixed in 32Front/21Rear For several rides to see if I am really ready for SS or if it's just my latest craze. I've been very disciplined in not using any shifting advantage and have walked a couple tough climbs that I have done in the past numerous times in 22/32. I've found almost no difference in my lap times on my favorite trail and I really enjoy the simplicity of SS. I am going to build one.

    My question is, if I build a 20# single speed should I stay with a 21 cog (3.2 ratio) or with the lighter bike and more efficient SS drivetrain should I just bite the bullet and go with an 18 cog (3.7 Ratio)?

    Like you said, cogs are cheap. I've got 17-22T in
    my parts bin. I use 20T most of the time (33x20), though. Start with a 20 or 21, and go from there.

    Ditto - I'm a relative newb and grabbed 17T, 20T and a 21T (given to me by a friend). I've used the 17T when I had the bike setup as a beach cruiser to pull the kiddo in a trailer, but use the 20T on my local trails and think right now, anything smaller and I would struggle.

    Start with 20T and go down from there!

    /\ This, expect to walk a few of the toughest climbs.

    My advice is to pick up a couple cogs but start low and work up. I recently went to a higher gear and found I climb better since I'm not spinning and wearing myself on level ground. But that's mostly pavement riding. I haven't been on the trails really since then. And don't be ashamed to walk it. After a few weeks it gets easier but I still walk it quite often.
    If I want the luxury of shifting gears, I'll drive my car.
