Campy seatpost binder bolt
I have a Marinoni SL with a Campy style seatpost binder bolt (non-tabbed, knurled) that is spinning in the frame. Does anyone have any experience with grinding a tab off a tabbed binder bolt and using two Allen wrenches to tighten the post? Are there any companies that make non-tabbed bolts without a Campagnolo price? I'm looking for a 20-22mm. Thanks.
