Mounted through the rear wheel spindle and swing arm, the nylon bobbins and aluminium support of Evotech Rear Spindle Bobbins for the Triumph Trident offer secure crash protection. The bobbins project from both sides of the wheel, intending to take impact first, should an incident occur to, reduce expensive damage. The innovative design by Evotech Performance allows the nylon bobbins to rotate above the aluminium core which can reduce stress and wear placed on the wheel.
