XRay X4 Aluminium Solid Layshaft & Bearings

The XRay X4 Aluminium Solid Layshaft and Bearings (XR305524) is a precision CNC-machined assembly that reduces rotating mass without sacrificing strength. Crafted from premium Swiss 7075 T6 aluminium and black anodised, the layshaft is engineered to minimise runout and drivetrain vibration for a smooth, balanced transmission.

Its super-narrow profile and square interface key the pulley securely, while the pulley can be retained with an O-ring or a C-clip according to driver preference. Two exchangeable bearings are included to further refine drivetrain smoothness.
