Park Tool 2197 DT-5/DT-5.2 Diamond Abrasive Adaptor for Carbon Fiber

The 2197 is an add-on accessory for the Park Tool DT-5 and DT-5.2 Disc Brake Mount Facing Set to enable easier and more efficient facing of disc brake mounts on carbon fiber frames. Features a brazed-on diamond grit surface that is over 100 times more durable and effective on carbon fiber than the cutter included with the DT-5.2. The 2197 sits between the cutter of the DT-5.2 and the brake mount and smoothly and evenly grinds the mounting surface until it is flat and properly perpendicular to the rotor.

Compatible with post mount and flat mount disc brake mounts

NOTE: The 2197 is intended for facing carbon fiber only. Aluminum steel and titanium disc brake mounts should be faced using the #2171 facing cutter included with the DT-5.2. For carbon frames that feature aluminum inserts (with a carbon/aluminum hybrid mounting surface) use the #2197. When machining carbon fiber regularly apply water (or a similar solution) to the cutting surface.
