XLC BR X50 disc

XLC BR-X50 brake disc

The XLC BR-X50 brake disc not only impresses with its 2-piece design but also with its technical advantages. The transfer of heat takes place towards the hub and therefore the bearing is less stressed. Also, the deformation of the disc is reduced and this therefore generates optimal braking. The braking surface is made of NIRO AISI 420 (an alloy of chrome and steel). The inner ring (the Spider) in 7075 aluminum with 6 holes is optimized in terms of weight.

Lightness

Lightweight parts are playing an increasingly important role in cycling technology. XLC parts and accessories marked with the XLC Lightweight logo follow this trend and have been developed by optimizing weight. Always taking care that operation and safety are not impaired by the lightness of the construction. It can be activated, maneuvered and stopped more quickly. Lighter weight makes it easier to transport by bus or train.
