    SF: What ratio do you rock?

    Hey all

    I've been trying to convince my friend from SF to give riding fixed a try, but he says the hills are too prohibitive. Granted, they are huge, but I know a lot of you ride fixed out there and I'm curious as to what ratio you use/strategies for dealing with the hills. My friend lives in mission and works over in the mission bay area.

    holla!

    46x17 and 49x18. anywhere from 69-73 inches should be fine. My main strategy is to go around the hills, haha.

    I live up by the panhandle, and work in soma. If i went in a straight line I'd hit some nasty hills, but if I do a little weaving around smaller streets I can do it with no problem, pretty fast... sfbike.org has a map that has hills marked that you can download or buy.

    Hills? Bah! You can get from the Mission to Mission Bay without ever going uphill

    I'm riding 44x16 right now, which is 63 gear inches, I think. My cog may need to be replaced soon, and when it does, I'm going down to a 17 in the rear. I do have to spin pretty fast on downhills, but I can get up most hills. Plus you learn to go around the ones you can't. I've never not been able to get where I want to go riding fixed - a fixie's been my only bike for the last year.

    EDIT: Oops, I'm riding *18* in the rear, not 16.

    Dude, I bet we ride parts of the same route a lot. I live near UCSF and work downtown - my usual route is panhandle -> Oak -> wiggle -> Duboce triangle -> Market St.

    44x16. onetwentyeight is right, go around the hills. actually, riding in SF, i've come to understand better where the hill ARE NOT, rather than where they ARE.

    other tips (mostly joking - you can make it anywhere in the city if you really try):
    - don't become friends with people who live at the tops of hills
    - don't take a job that's at the top of a hill
    - don't let your favorite bar be at the top of a hill
    - don't take an apartment that's at the top of a hill

    anyway, from what you've said, your friend has tip #2 and #4 taken care of already. Mission District -> Mission Bay is as flat as can be.

    46x17. head down 16th to 3rd and hanga left/right to get where you need.
    should be mostly flat on 16th work up to 17th and potrero for more hill goodness.

    it's less trafficky (and an easier climb) to take 17th from harrison and across potrero...

    SF - I miss you!

    Wanted to come down to visit before flying home - but I fought the law, and the law won...

    (46:18) 69 all the time.

    Here's a pic of a SFmessenger mate of mine who crazily worked on 49:16 or something HUGE. He could pull a wheelie (manual) and ride out of sight - FAST!
