The spindle head of the RS660 protects the driveline by protruding from the rear wheel, aiming to absorb impacts before reaching the swing arm. Its design allows the nylon bobbin to spin above the aluminium core, enhancing durability and reducing stress on the wheel. The bobbin is secured in the wheel with a spindle rod.

Features:

• Spindle Bobbin fixed on the driveline side
• Protects the costly swing arm and sprocket carriers
• Bobbin created from hard-wearing nylon with an aluminium base
• Held through the rear wheel by a stainless steel spindle rod
• Replacement bobbin heads are available to purchase
