X4 aluminum layshaft is strategically CNC-machined to attenuate rotating fat without compromising strength or integrity. The precision layshaft minimizes runout, eliminating drivetrain vibration and creating a confident stability. The layshaft includes two exchangeable bearings to help minimize drivetrain vibration. The layshaft features super narrow design and a square form where the pulley is keyed towards the construction. The pulley is secured by an O-ring and/or C-clip depending on the driver preference. Machined from premium Swiss 7075 T6 aluminum and black anodized.
