Singlespeed & Fixed Gear - Someone explain GI to me.
Bikeforums.net is a forum about nothing but bikes. Our community can help you find information about hard-to-find and localized information like bicycle tours, specialties like where in your area to have your recumbent bike serviced, or what are the best bicycle tires and seats for the activities you use your bike for.
How is it calculated, and what does it mean?
Maybe this (http://en.wikipedia.org/wiki/Gear_inches) will help.
Oh, I get it now.
More gear inches=stiffer gear. Hence the constant penis size comparison jokes. Coolbeans, thanks for the link.
In the context of fixed-gear, what is a reasonable GI for a reasonably in-shape person (but one who has been riding with gears and has never ridden FG.)?

try something in the 70" range.
So 42x16 or 44x17 would be good noob gears?
Yea, I was going to say anything from 60-80 depending on elevation changes.
If you have access to a geared bike, try it out there. 42x16/17 is pretty common.
