Gear Bike
What's a good gearing ratio for a fixed gear bike?
I live on the campus of North Carolina State University. I'm going to convert my road bike to a fixie and was wondering what everyone thought. It's semi hilly but not anything too terrible
Bike guru Sheldon Brown recommended a gain ratio of 5.75 to 6 He ran a 42/15 setup with 165 mm cranks for an area that he termed "semi-hilly".

If you don't feel like using the online gear inch/gain ratio calculators, I'd just ride around the campus in the middle chainring and figure out which gear on the rear cassette best allows you to ascend hills and keep speed on the descent.
