dude this looks really sick..ive been riding a hard tail recently and its so hard for doing DH..for that course is it absolutely essential to have an full suspension frame? im 16 and im looking for some riding buddies my age, but havent really gotten into the DH stuff yet...really want to though...thanks for the report and awesome video
actually, there was a guy on a rigid 20" BMXer riding the DH course (quite well in fact). check out dirtymike's video somewhere earlier in the thread.
and don't worry about riding a hardtail for DH. you just need to pick smoother lines, and not necessarily the line that everyone else is taking. I think it's good for you in the long run, and you'll feel SO fast on a FS the first time you ride one on a DH track.
