This MMR single-piece crank hub features a 4-pin dowel locking system that mechanically secures the hub to the crankshaft, eliminating the risk of hub slip. CNC-machined in the UK from billet EN36 steel and case-hardened for maximum strength, it delivers a major reliability upgrade over the OEM design. Supplied as a complete kit, it includes precision dowels, a new OEM crank bolt, and a dedicated installation jig to ensure accurate and safe professional fitment.
