I've heard that Brian Lopes takes both his hardtail and his full suspension 4X bikes when he goes to a race, just so he's prepared for whatever kind of track he might encounter. In fact, I've read that he has been known to qualify on one bike, then race the other! That just sounds crazy... Can anyone corroborate this story? I usually have to "run what I brung" but man... if I had that kind of action going on I'd be tempted to bring both of my bikes too! How cool would that be?
