Thule's 594XT Sidearm roof carrier attaches to Thule rack systems and load bars to transport a single bike. The carrier's SecureHook holds the bike by the front wheel, preventing damage to the bike frame. This versatile design allows the carrier to work with a variety of bikes, including those with non-traditional frame designs. The aluminum wheel tray provides maximum strength and rigidity. All Thule equipment passes tough European safety standards for car racks.
