DCA-1 Digital Caliper Accessory

The Park Tool DCA-1 Digital Caliper Accessory is a must - have for ensuring your bike's safety and performance. Regularly checking disc brake rotors for wear is crucial. This accessory can be easily installed on most digital dial or vernier calipers, including the Park Tool DC - 1. It features unique protruding contact points that let you measure the center of the braking surface, bypassing the unworn edge for an accurate reading. Moreover, its conical end points are perfect for measuring the center - to - center distances of bolt holes, which helps in calculating the bolt circle diameter (BCD) of chainrings and cranks. It's compatible with most standard vernier dial and digital caliper designs, making it a versatile addition to your bike maintenance toolkit.

Using the Park Tool DCA - 1 Digital Caliper Accessory is simple. First, install it onto your digital dial or vernier caliper. When checking disc brake rotors, place the accessory so that the protruding contact points can reach the center of the braking surface, avoiding the unworn edge for an accurate measurement. To measure the center - to - center distances of bolt holes, use the conical end points. For best results, make sure your caliper is clean and in good working condition before installing the DCA - 1. After use, clean the accessory with a soft cloth and store it in a dry place. Avoid exposing it to extreme temperatures or rough handling to maintain its accuracy and longevity.
