Interesting question. If I'm down on my aero bar, I can wind up to about 35mph+ (or I could on my road-racer with Zipp 440's anyway). Not sure I could sprint much faster than that!

Maybe I'll try out a sprint in each direction on a level section of 29th Avenue with my ol' Cannondale, as well as some all-out aero-bar bursts, and post my findings here. But your 38mph+ sprints sound mighty fine to me!
