Problem Solvers Shim Seatpost

Available from Ascent Outdoors when we last checked. Sold from the shop’s own store; the price there is the one that counts.

The Problem Solvers Seatpost Shim is what you need when your seatpost is a little too small-diameter to fit tightly into your frame. It's made of light, durable aluminum and has a lip on the top so it won't slide down inside the frame during installation.
