TRC-14 style carrier also can be used to install 2014 front Touring or T14 composite (11.5"and 11.8") rotor on Harley or custom motorcycle. Available for front and rear.
Carrier can be finished in Chrome, Polished, Anodized Black or a powder coating of your choice. Can be purchased with a set of 5 chrome screws (5/16-18, 7/8"), bushings and spring washers
