Ya-Hoo! I hit a new speed record!

I weigh less than my DH and we ride the same model bike (mine is a bit smaller), but I pass him on the screaming downhills when neither of us are pedaling at all and both in similar posture- I can't quite figure it out- any ideas why?

Lisa, you most likely have a smaller frontal area than him, creating less aerodynamic drag. Are you shorter than your DH? Is your bar lower than his? That would account for your ability to coast down faster.
