It is essential to make sure of the type of disc you need before ordering by checking its dimensions. The outside diameter of some brake discs may differ from the original assembly, a dropout (adapter) must then be added in this case. It is also necessary to replace your brake pads when changing the disc. Also remember to put a drop of "thread lock" type glue on the disc screws to prevent them from loosening.
