Park Tool DT-1, Disc Brake Mount Facing Tool

Information

In order to ensure disc brakes function smoothly and accurately, the frame’s mounting tabs must be parallel with the brake pads and rotor. The DT-1 is designed to perfectly machine the face of each tab, removing paint and material to create a flat surface.

The DT-1 works on 135mm rear frames with the "standard" 10mm axle dropouts, and 12mm through axles by using a spacer included with the kit. The DT-1 also works on front forks with 100mm axle width and a 9mm axle dropout, and with 20mm through axles by using a spacer included with the kit. For bikes with the 12mm through axle, use the axle from the bike and the bushing included with the DT-1. For 20mm front forks, use the axle from the fork and the bushing included with the DT-1.
