Saddle wont stay in one place

jpstar

Basically the problem is, as tight as I do the bolt on the seatpost to hold the saddle in, the saddle still moves. It's driving me mad, because it moves forwards, backwards hell it even wobbles sideways and vertically! The bolt cannot be done up any more than it is now either which is confusing me. Its moveable if you give it a sharp whack with your hand, there does seem to be a point where it doesn't wobble though (about in the middle of the rails) otherwise, its wobbly. It moves while riding, I'm thinking the trail vibrations cause it to move, but I just don't understand, it shouldn't be moving in the first place! It's recent as well, past few months... Didn't do it before hand.

Any help is really appreciated, this is just annoying now... :evil:

What seatpost and what saddle?

jpstar

Seatpost is a Aluminum micro-adjust (One bolt construction if it helps) and the saddle is a Spesh Softlite. But bearing in mind these are from the last millennium... No obvious signs of damage to either component though.

Take it all apart and thoroughly degrease. Check nothing is worn or damaged. Can lightly rough up the rails and cradels with emery paper too to add grip.

You havent stripped the bolt in the clamp have you overtightening it? Try replacing the nut and bolt in the clamp.
