Park Tool SAC-2 Supergrip Carbon Assembly Compound

Helps create a tighter grip between two slippery surfaces. Ideal for carbon, aluminum, and steel seatposts, handlebars, and stems.

4 oz. (113 g) tube

Note: Assembly compounds hold by using grip aided by small bits of hard silica. This silica may cause minor cosmetic blemishing. Do not use SAC-2 on threaded parts or for bearing lubrication.
