[QUOTE=Hermes;7450332]My top speed is elusive since our terrain is hilly and we have a lot of wind. The best data I have is from the track last week where I did 32.4 mph from a standing start in 500 meters. I used a 51/15 gear. Since I went around the track, it was flat and wind to an extent canceled out. I was accelerating at the finish so I could probably got up another 10% with that gearing.[/QUOTE

Nice job Hermes. Any idea what your cadence is at 32 mph? When I do my sprints from a standing start I begin in 50/18 and drop gears two at a time once the cadence is above 120. I get seated near the end to be more aero and am somewhere around 130 in the 14 or 13. You must be spinning around 150 to 160.
