The Park Tool 2197 DT - 5/DT - 5.2 Diamond Abrasive Adaptor is a must - have for carbon fiber bike maintenance. It's an add - on for the Park Tool DT - 5 and DT - 5.2 Disc Brake Mount Facing Set, making disc brake mount facing on carbon fiber frames a breeze. Its brazed - on diamond grit surface is over 100 times more durable and effective on carbon fiber than the DT - 5.2's cutter. It sits between the DT - 5.2 cutter and the brake mount, smoothly grinding the mounting surface flat and perpendicular to the rotor. This adaptor is compatible with post mount and flat mount disc brake mounts. Note that it's for carbon fiber only. Use the #2171 facing cutter for aluminum, steel, and titanium disc brake mounts. For carbon frames with aluminum inserts, use the #2197. When working on carbon fiber, regularly apply water or a similar solution to the cutting surface.
Using this Park Tool 2197 DT - 5/DT - 5.2 Diamond Abrasive Adaptor is easy. First, attach it between the cutter of the DT - 5.2 and the brake mount on your carbon fiber bike. Then, start the grinding process to make the mounting surface flat and perpendicular to the rotor. Remember, this adaptor is only for carbon fiber. If you have aluminum, steel, or titanium disc brake mounts, use the #2171 facing cutter that comes with the DT - 5.2. For carbon frames with aluminum inserts, you can use the #2197. During the machining of carbon fiber, make sure to regularly apply water or a similar solution to the cutting surface. This helps with the process and keeps the tool in good condition. After use, clean the adaptor thoroughly and store it in a dry place to maintain its performance.
