This adapter enables the installation of a 180 mm rotor on the Teammachine R 01. It is specifically designed to increase clearance between large-volume brake calipers—such as the SHIMANO Ultegra BR-R8170—and the seatstays on frame sizes 47 and 51. For frame sizes 54 to 61, standard SRAM or SHIMANO brake adapters are compatible and provide sufficient clearance.
