Saddle Slipping?
I've been riding a Specialized Toupe Saddle on a Campy Record seatpost for a year with one problem. Then, last week, my Toupe saddle slipped nose up during a ride. After four repairs roadside tightening as hard as I could turn with my allen wrench, it kept slipping nose up.
I took to the LBS and they said the Record seatpost has had proble with slippage and he showed my how the teeth on the clamp was worn and seemed to not be able to grip the seat rails. So I switched to the Bontrager XXX Light Seatpost. 10 miles into my first ride I heard a little tick and the nose of the seat slipped up slightly. The saddle stayed in place for the remaining 50 miles but the slight angle upward bugged the hell out of me. On my last two rides this week I leveled the seat and tightened but always get a slight shift of the nose upward during the ride. The saddle doesn't move around just a slight shift nose up from level. No matter how tight I get the clamp it still happens. Any suggestions? |

Re: Saddle Slipping?
Do you have your saddle set back really far? If so, consider turning the post around so the clamp is more mechanically efficient...
Try a little grease on the bolt threads... Take the post to a machine shop and have them modify the clamp, maybe with a shim, to increase the 'grip' between the post and clamp... Just some ideas. Or get a Thompson. Bullet-proof! |

My old Super Record post would always slip like that until I bought a replacement binder bolt at an industrial fastener shop. Because it's a hardened and has a larger head I can torque it down harder. Problem solved. |
