After building up my first fixed-gear, I recorded a couple of points of reference: Fixed Gear Speeds at Specific Cadences GEARING Revolutions Per Minute - Speed Parasonic w/ Speedblends 42 x 15T w/ 700x32c tires = 75g" 60 - 13.5 mph, 80 - 18.0 mph, 100 - 22.5 mph, 120 - 27 mph Dawes w/ Conti's 42 x 16T w/ 700x25c tires = 69g" 60 - 12.4 mph, 80 - 16.5 mph, 100 - 20.6 mph, 120 - 24.7 mph Quickbeam Gearing 40 x 18T/16T/15T/14T w/ 700x32c tires = 60 - 67.5 - 72.5 - 77g" @90 rpms: 16.1 mph - 18.1 mph - 19.3 mph - 20.7 mph AASHTA - From Sheldon's Gear Calculator (pull down menu, after "Meters Development") http://www.sheldonbrown.com/gears/ His advice for gearing selection still is the most cogent ever given: "low enough that I can make it up the hills where I usually ride, but high enough that I can go reasonably fast down the other side."
