Ritchey Comp Zero Seatpost

A zero-offset post places the saddle clamp directly in line with the seatpost tube, rather than pushing it backward. This encourages a more forward, aggressive riding position, which can help you get more power into the pedals, especially during climbs or sprints.

This specific model has a 27.2 mm diameter. You must check your current seatpost or your bike frame's specifications to ensure this matches; if your frame requires a different diameter, this post will not fit.

The standard rail clamp is designed primarily for traditional round metal saddle rails. If you are using a saddle with oversized carbon rails, you may need a different clamp adapter or a post specifically designed to accommodate them.

While exact weight can vary slightly by manufacturing batch, this aluminum post is designed to balance durability with weight savings. It is a reliable, mid-weight component suitable for daily riding and training rather than ultra-lightweight racing builds.

Yes, you can trim the seatpost to a shorter length if necessary. Just ensure you leave enough post inside the frame to meet the minimum insertion depth marked on the tube to maintain structural integrity.
