Slipping seatpost???(4 posts)

Hey all, just got my new bike rolling this weekend. So far so good, but I am having a small problem with the seatpost slipping. I set the post to the height i want and then within a 1/4 mile it drops about 1/8" so far no more. I have a 2000 Schwinn Paramount with fastback seatpost clamp. The size of the seatpost is right. I have cranked the bolt as tight as I dare for fear of stripping. Any ideas how to fix this.

Ride on...

Could be the tube or the post is slightly out of spec--I had the same problem on a Cannondale, and I never did really get it to hold.
An old-time LBS owner suggested cleaning off the grease from the post and tube, then smearing some valve-grinding compound (cheap at auto supply places) on the post. It's a mild abrasive. I didn't try it (I wanted a new post anyway, because I'm a Clydesdale and I didn't trust the OEM one; that solved my problem), but for what it's worth, there it is.

find a seatpost reflector with clamp, take the reflector out, tight the clamp on the post. it will have two clamps to slip through.most likely it won't.

I had the same problem when I bought my new road frame. The problem was the binder bolt. It was too long. I replaced it with a Campi binder bolt. No more problem.
