Crown Race Setting System

The CRS-1 is a professional tool set for installation of crown races onto forks with 1" and 1 1/8" steering columns. Using the long, strong driver tube, one of the included drifts, and a hammer or mallet (not included), the CRS-1 safely and accurately drives the crown race into its properly seated position.

Includes six specially-sized drifts — three in the 1" standard, three in the 1 1/8" standard — for compatibility with most crown race shapes and designs. Each drift is made from anodized aluminum to avoid damaging the crown race.
