So, over the course of several months, I notice that my saddle has been creeping backwards on the seat post.
Road bike. Fizik seat post (two screws, one manual, one hex head.) Ti rail saddle.
I tend to break seat rails. I think it is fatigue related. And I range between 200 and 200 lbs. ;) I've used steel rails. Carbon rails seem like a bad idea. The current saddle has ti rails. I put the saddle forward because the break in the rails happens at the back, and I want to minimize flex. This is my current theory to stop breaking rails.
Anyway, I tighten the bolt plenty. I don't know how much, but I think that increasing the clamping force is not going to help, and I will eventually strip the bolt/nut.
Seems like more friction between the rails and clamp is what is needed. I don't know the proper way to do that. Any suggestions?
