Excuse the ignorance, but I just picked up a Suntour Superbe Pro crankset with a 49 tooth Sugino 75 chain ring with which I plan to convert an 86 Peugeot Triathlon (PSV).
What would you suggest is the best cog size for me to use in a relatively flat city (Boston). I'll need to clear a few hills, but I hate spinning crazily when I'm on a nice clear bikepath. Does 17t sound right? Should I go lower?
I'm with Scrod. 17 or 18 would be most comfortable, and best for all-purpose fixed riding. If you're going to use it to race, you might go 15/16, but I think 17/18 would be far better for a street bike.
I run 48/17 and its great. My commute has a few decent hills and a few decent downhills. I spin at about 25MPH on straights/slight downs and never have a problem with spinning out. I can handle most "hills" without standing and pedalling. i think its my ideal ratio for now. Probably going to try a 19t out.

I'm in Boston too, and I ride 48/18 every day. In my opinion, it's a good ratio for the area, but it might be too high for someone who rides only occasionally or someone who wants to cruise a little easier on flat sections.
