    help with gear ratios
    I have a 50t crankset, I'm trying to set up a SS commutter. Any suggestions for a rear cassett?? My commute is mostly flat but I'd like a set up that I could climb with as well.
    Any help is greatly appreciated.

    Thanks

    check the online shops -- price point, performance, etc.; they have SS conversions that fit a 9-sp cassette body.

    Look for about a 26-tooth gear for the rear wheel, something close to that.

    Is it a 26" wheel? If so, I'd put a 19T in the rear. Something around 70 gear inches. If you like to spin go lower, like 65.

    700c X 22.5

    My previous statement still stands then as the OD is practically the same.

    I have 700x23 and it is about 70 inches. Makes the commute fast and hills tolerable. Anyway, here is a good site for future reference.

    Agreed. 70-71 gear inches is good for a SS commuter. Fast enough and you can still climb hills.

    52:20 gives me about 71 gear inches on my commuter with 27" wheels.

    39, 42, 44....
    I started with a 39x16, then went to 42 and still spun out way to fast. The 44x16 with 700c wheels is just about right, but I think I'll try a 46 or 48 next. The rings are so cheap and available via ebay, it almost costs nothing to expirement. I'll have to replace my chain though if I go up another half inch.

    Without wind, I can spin pretty fast at 20-21.5 mph at 44x16. I'm worried about hills though if I go up any more. Let me know how it goes.

    I agree, get a 19 or 20 tooth cog for a 50T chainring
