I gotta know gear inches. Front, back, big, small means nithing. Its gear inches that I go by. 88" gear is the "racers" gear. 84" gear is what Ray Booty broke the 4 hr 100 mile TT on. 67" is the early season fixie gear. Anything below 50" is a climbing gear.
I use a 2 × 5 setup. 42/55 with a 16-24. Big ring gives me 67, 75, 82, 93. Really nice progression of gears. The 42 gives me three low gears if I run into a hill.
