Thule's Sprint Fork Mount combines security and convenience to make racking your bike easier than ever. The AcuTight knob clicks like a gas cap when you reach optimal hold to ensure that your bike is secured to the rack. Move the telescoping wheel tray in and out to customize the rack to fit your bike, or to simply get out of the way for greater hatch clearance on your vehicle. Vibration damping elastomers on the mounting surfaces and wheel tray help absorb road shock from making its way to your frame and wheels. Thanks to the ratcheting strap, it handles tires up to 2.6-inches wide and high-profile rims with ease. And, Thule's One-Key lock cylinders (sold separately) make it easy to secure your bike to the Sprint and your Sprint to your roof rack.
