This is Real World Cycling's recommend tool for installing or removing their Shock Eyelet Needle Bearings. It prevents needle bearing cup damage by properly aligning the bearing with the shock eyelet. You can use this tool with their Enduro Hub Bearing Press handles (not included), a vise, or a threaded rod with washers and nuts. One side of the tool is optimized for bearing installation and the other side is optimized for bearing removal.
Designed for use with shocks that have 15mm eyelets (as measured with the DU bushing removed). Cutouts on the tool body allow it to fit into the tight quarters of the Cane Creek Double Barrel shock eyelets.
