Steve --- I had a problem with my PX-10 breaking the binder bolt because the bolt was too long for the seatpost binder "ears." The binder bolt would bottom out before achieving clamping pressure sufficient to keep the post up. I muscled the thing down as hard as I could (When all else fails, force it. If it breaks it needed replacing anyway. Isn't that the old wisdom of this sort of situation . . . ?) When I realized the nature of the problem, with a new binder bolt similarly failing to grasp the seatpost tightly enough, I found a little washer to put on the inside of the "nut." That little bit of extra grasp on the seatpost fixed the slipping problem and I haven't had to adjust my seatpost in 2 years. Nor have I broken a binder bolt in that time. --- David Faulkner in Sacramento
