What type of downhilling are we talking about here? When you say DH'ing I think hitting the double black diamonds at Northstar at Tahoe. If you are talking about that kind of DH'ing that bike would be chewed up. So if you could post your definition of DH'ing will will be able to tell you if it would get killed or not. Also it depends if you are a flowy rider and can pick a decent line.
