I have a onone 456 summer season.
27.2 seatpost and 29.8 clamp.
When the seat post is up I have to use less pressure on the clamp to keep it where it is supposed to be than if it is down... What is going on here? New seat post? weird tapered seatpost being the issue? Its not bent as far as I can tell...? weird
edit: not saying the post is tapered.
