Park Tool Caliper DCA-1 Disc Caliper Adapter (SKU 611017)

Measure rotors more accurately with the DCA-1 from Park Tool. It installs onto most digital, dial or vernier calipers, and its protruding contact points measure the center of the braking surface rather than the unworn edge of the rotor. The conical end points also measure center-to-center bolt hole distances, so you can calculate the BCD of chainrings and cranks. Clear.
