Park Tool DCA-1 Digital Calliper Accessory

Park Tool DCA-1 Digital Calliper Accessory

• The DCA-1 digital calliper adapters can be installed on almost any digital, dial or vernier calliper.

• Special contact points bypass the unworn edge of disc brake rotors to provide an accurate indication of wear.

• Can also be used to easily measure the centre-to-centre distance of bolt holes allowing you to calculate Bolt Circle Diameter (BCD) of chainrings and measure spoke hole diameters in the hub flanges when determining spoke length.

• Easily installed with the included 1.5mm hex key.

Disc brake rotors should be regularly checked for wear to ensure safety and performance. The DCA-1 installs onto most digital, dial, or vernier callipers (including the Park Tool DC-2) and features protruding contact points that allow measurement of the centre of the braking surface, bypassing the unworn edge to ensure an accurate measurement. The conical end points of the DCA-1 can be used to measure centre-to-centre distances of bolt holes for calculating bolt circle diameter (BCD) of chainrings and cranks.

Features:

• Compatible with most standard vernier, dial, and digital calliper designs including the Park Tool DC-2.

• Fits the Park Tool DC-1 and DC-2 digital vernier callipers.
