The wheel dampers AKA cush drive rubbers, inside the sprocket carrier play a crucial role in your drivetrain—they help absorb shock and reduce stress during acceleration, deceleration, and gear shifts. Keeping them in place extends the life of your transmission, chain, sprockets, carrier hub, and rim/hub.
However, for high-performance engines, racing, or aggressive riders who value precise throttle response, a tighter drivetrain feel is key. Upgrade to Chimera Engineering Polyurethane "Super Stiff" Cush Drives to dramatically reduce driveline lash and deliver sharper, more responsive feedback! This is very close to a solid hub, minus the shock and stress to the drivetrain. Whether you're racing, riding, or cruising, having Chimera's Super Stiff Cush drives in your drivetrain is a great upgrade!
FITMENT:
NOTE: It's a tight fit when it's new; you may need to use a rubber mallet to help tap the cush hub into position.
