Brother Cycles Thru Axles
Brother replacement thru axles are offered in eight specifications for different frame and fork generations. The options cover rear and front axles, Boost and non-Boost spacing, and the later Mehteh UDH rear arrangement.
Hub spacing alone is not sufficient to select the right axle. Match the overall axle length, thread pitch and threaded length to the frame or fork, using the option table below. In particular, the different Mehteh carbon-fork generations and the UDH rear axle use distinct specifications.
Choose the numbered option that matches your bicycle rather than assuming every axle carrying the same model name is interchangeable. The supplier photograph is illustrative; the appearance of the delivered axle may differ according to the specification selected.
