Wolf Tooth Post to Flat Mount Brake Adapter

This adapter allows you to mount flat-mount disc brakes to frames with post-mount bases. Requires a rotor 20mm larger than the rotor size before using the adapter. (If using a 140mm rotor, replace it with a 160mm rotor, and if using a 160mm rotor, replace it with an 180mm rotor.) A minimum of 13mm of clearance is required for installation (see image 5). Weight: 17g. Material: 6061-T6 aluminum. Compatible rotor sizes: 140mm, 160mm, 180mm (before using the adapter).
