Install the XRAY 375043 - X12 Aluminum Rear Wheel Hub with M2 Screw to lower unsprung weight and improve rear axle stability. The integrated one-piece form removes extra shims and keeps the rear end neater for setup work.
Made from Swiss 7075 T6 and CNC machined for consistency, this hub combines light weight with strength. The black anodized finish helps protect the aluminium, and the narrow footprint with an M2 screw secures wheels tightly.
Specifically built for X12 models, this hub helps reduce rotating inertia so you get firmer acceleration and improved turn-in. It is a practical upgrade for weekend racers and club competitors.
