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)

42 x 15 for 75.6 Gear Inches

Works okay for climbing as long as the climb is not too steep or too long, tops out at 27-28 on descents.

40/16 on one bike, 45/18 on the other....I see a ton of steep and sustained climbs. Both are super easy to pedal on the flats.

Sheldon says 82.8GI. So about 83

Wheel/tire size play a role in it. My current whip is a pos conversion with huge 27 inchers. Makes a ~2GI difference over a 700x23.

44 x 18 and mostly freewheel, not fixed.

My 25mi r/t commute has just over 1800' of climbing. 65.4 g.i. is plenty for me when contending with 3 ascents of 7% grade sustained over at least 1 mile.
