The guys I ride with who mountain bike are great at handling, and they seem to have no fear on the downhills. I'll be going 45 feathering the brakes, and they'll be getting aero and trying for 60

They also seem much surer of themselves riding shoulder to shoulder in a pack.
The team I'm on is mainly into mountain biking (I'm the only pure roadie), so I'm going to start doing some NORBA races. We'll see if I fall as much off road as I do on it.
