    Gear ratio advice.

    I want to climb one of the local mountains, anyone with experience, what gear ratio would be appropriate for a constant 6%+ grade for 28 miles? My two-speed setup that will be finished soon will have 66/60gi. Spinning out is not an issue.

    Here's a chart I found:

    Being a Newbie I have no idea what you should use, but WOWZA! 28 miles at a 6% grade, I think I would give up about a mile in. Best of luck

    I think I'd rather not walk uphill for 28 miles. Haha. Those ratios are with 37c tires, maybe I could use skinnier ones for the climb and it would lower the gi a bit.

    I'd go 35-45 GI, personally, but that's just me.
    I'll eat it first.

    I think you'll be fine with 66. It will just all be about pacing yourself. I think that is the biggest challenge.

    It all depends on your personal fitness. I would go around 66 on a fg.

    Remember you have to come down the hill too. If your using a flip/flop you may want one gear for going up and one for coming down.

    Are you going ss or fixed? Road or mtb?

    Grab a road bike and try the first 4 miles of it. See what gear you like most. Duplicate.

    1. You're crazy! (crazy = much more motivated than me.)

    2. What kind of hub do you have? Flip flop? You said it was a two speed. My commuter is a "two speed" using a Shimano Freehub and a double chainring. I have 48/18 for riding around town and 40/25 for going offroad and other goofing off.
