    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.
    A bike is the only drug with no bad side effects....

    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.

    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.
    Check out some of our local hills: CDRC (Capital District Road Climbs)

    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.
    Just Ride!

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

    Just keep spinning. Just keep running. Just keep paddling.
    Just keep moving forward.
