The Sport Rider fits all bikes using a padded universal top clamp and adjustable wheel holders. It is quick and easy to use, and at under $199 MSRP, the Sport Rider won't put a big dent in your pocketbook! Simply drop the bike into the wheel holders, then slide the clamp down onto the frame to secure the bike. Also includes velcro wheel straps and nylon safety strap for extra "bike holding" security. Includes Hollywood's "No Wobble" threaded hitch pin that prevents rack sway. Fits both 1-1-4" and 2" trailer hitch sizes
