The Campagnolo binder bolt is not one of their best parts. The Simplex bolt is considerably more resistant to stripping. It's the best in my opinion and what I stocked in the shop way back. The TA bolt is also better and available (was available?) in a longer length. The Sugino bolt was also better than the Campy.

> 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
