The Problem Solvers Brake Boss Plugs are perfect for when you've removed your cantilever or linear-pull brakes in order to run disc brakes or a fixie setup. These plugs thread into the empty frame bosses and lend a clean look, while also protecting the threads inside the frame from corrosion.

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.
