    whats a good gear ratio?

    So i recently purchased a cheap track frame from a friend of mine for 30 bucks and seeing as it's not my main bike( i have an 18 speed road bike) i'm going to customize the hell out of it to make it a complete hipster stereotype, might as well right? i've already made my mind up on most of the components, the only thing i haven't decided is the gearing ratio. being used to a geared bike, gear ratio isn't a big deal seeing as you can't shift. I'm looking for something that i won't end up pedaling my ass off too much on downhills but will allow me to go uphill without vomiting in pain. suggestions please.

    Most people use gearing in the 70's range. It depends a lot on the terrain and also whether you do a lot of stop and go. I'd get a crank with a 46T or 48T chainring and start out with a 17T chainring and see how it feels. If it feels to low, change to a 16T, if too high then an 18T.

    Are you planning on skid stopping? (i'm assuming you're building fixed, not free). # of skid patches may be a consideration. See http://fixedgearwales.blogspot.com/2009/01/ratio.html

    I ride 48x17 in the city with small hills (Central Park) without vomiting in pain. I do not regularly skid.

    Since style is a concern, I suggest larger gears rather than smaller ones. I think they look cooler. For example, 52/26 and 40/20 will give you the same ratio but a large chainring looks more "track"-ish. (I don't suggest a 2/1 ratio, that's just an example. Also, I imagine a 26T freewheel or cog might be hard to find!)

    Food for thought: if you aren't dead by 2050, you and your entire family will be within a few years from starvation. Now that is a cruel gift to leave for your offspring. ;)

    Live in Portland.
    Ride downtown and to the top of Sandy blvd 4 times a day.
    I run 46/16 its perfect for the flats but killer on any "major" hills.
    I want to spin just a bit more so I will switch to a 17-18 cog.
    Spinning more/quicker makes for stronger legs in the long run.
    Good luck.

    You think you guys have steep hills?
    Check this out. Then tell me what ratio you would use!

    +1 Am thinking of going to 48x15. The terrain around my place is rolling hills and flat w/some 12-18% killers. No trouble on a geared bike, but gotta do switchbacks on my fg. Depends on your terrain and conditioning level.

    I had 53x15 for a flat 10 mile TT this summer. It was perfect for that, but way too heavy for me to just ride around.

    I dont do any racing. I dink around on the velodrome every once in awhile but surprisingly, the gear doesnt seem that hard so I stick with it.
