JT Sprockets TwinStar Rear Sprocket T40 Orange (JTX897.40ORG)

The TwinStar orange edition combines a vibrant aesthetic with professional-grade engineering for riders who demand both style and substance. This hybrid rear sprocket significantly reduces rotational mass while providing a hardened steel contact surface for the chain.

• Features 40 teeth designed for high-speed stability and smoother power delivery across the rev range.
• Inner carrier is anodised in a striking orange finish to resist scratches and chemical damage.
• Lightweight aluminium core helps improve suspension response by reducing the unsprung weight of the rear wheel.
• Steel outer teeth are induction hardened to ensure they outlast standard all-aluminium sprockets.
