Top speed on my regular commute route is 42 mph - coasting in a tuck down the hill that leave from my house.

Top speed on my secondary commute route is 48mph pedaling down the hill behind where I work.

And top speed overall is 50mph - also pedaling down the other side of the hill from my house (yeah, it sucks to have to ride home).

All riding a 2007 Tricross Comp.
