Park Tool DCA-1
The Park Tool DCA-1 is a digital caliper attachment that lets you measure brake rotor thickness and bolt circle diameter with precision contact points bypassing worn edges. It fits most digital and dial calipers, making it invaluable for brake service and chainring assessment.
- Installs onto most digital, dial, or vernier calipers (including the Park Tool DC-1)
- Features protruding contact points that allow measurement of the center of the braking surface, bypassing the unworn edge to ensure an accurate measurement
- Conical end points can be used to measure center-to-center distances of bolt holes for calculating bolt circle diameter (BCD) of chainrings and cranks
