Saris' Sentinel Bike rack is ready to go right out of the box, easy to mount, and, thanks to its narrow arm spread, securely holds three bikes. The frame adjusts to the contours of your car and folds down flat for simple storage. To protect your car and provide a solid mount, the hold-down straps have coated hooks, while the legs are foam-padded. Stiff ratcheting straps ensure a firm grasp on your bikes.
