Thule

Thule's Sidearm is perfect for bikes with non-traditional frame designs or unique fork/hub interfaces because it holds bikes by the wheels only. For fast and easy loading, Thule's ratcheting SecureHook clamps the front wheel, while a ratcheting strap secures the rear. The Sidearm accepts most bicycles including those with 29-inch wheels. This fine bike mount fits on square and round crossbars (sold separately).
