I've got a "Profile" brand seat post that keeps coming loose at the saddle connection. It used to do it once in a while but I recently put a Brooks B-17 saddle on there and it seems to loosen up ever couple hours of riding now. I don't know what the saddle type would have to do with it but that does seems to be the case.

The seat post is 12 or 14 years old. Maybe the teeth on the adjustment part are just worn and I should replace the post? If that's the most practical choice, what is a decent, reasonable light replacement that people have been happy with? It's a 27.2 if that makes any difference.

Thanks,
Bob
