Singlespeed & Fixed Gear "I still feel that variable gears are only for people over forty-five. Isn't it better to triumph by the strength of your muscles than by the artifice of a derailer? We are getting soft...As for me, give me a fixed gear!"-- Henri Desgrange (31 January 1865 - 16 August 1940)

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.)?

If you have access to a geared bike, try it out there. 42x16/17 is pretty common.
