advice for slipping seatpost...(5 posts)

advice for slipping seatpost...dawgcatchr

My post keeps slipping. It is an USE Alien Aluminum mated to a Colnago CT1. I already broke one seat clamp bolt by over-tightening it because I was tired of the seatpost constantly slipping. Any recommendations on no-slip posts or super-powerful seat binders?

I know that hair lacquer works on carbon seat posts but dont know if it would do on alluminium.
What you do is spray onto the post, wait until it has dried then insert into the seat tube and tighten. Works woneders.

I have tried this before on my touring bike and it worked.

Cut out a small piece of alluminium sheet from empty soft drink can and use it like a "shim". Insert it between the seat post and seat tube. It may not look cool but it should work.

refer to link if you are interested in bicycle fabrication.

What type of binder does the CT1 use? I remember that on more than one occasion. The Campy binder on my De Rosa and other steel bike would actually bottom out. In other words, the shoulder of the bolt side and the shoulder of the nut side would contact before it could tighten enough to hold the post from slipping. I just ground down the nut a little on a belt sander to fix the problem. If thats not the problem, then I would go to the shop and have the post measured for size. It could be at the lower limit of it's tolerance.

Try the Campy Record clamp designed for their carbon posts. I have a C40 and replaced the Colnago clamp with the Campy clamp. Works like a charm and very well designed.
