The RockyMounts Switch Hitter Bike Mount is a versatile fork-mounted bike carrier, attaching to virtually any crossbar system with its universal mounting hardware. T-track hardware is included for slotted bars. Lightweight cast aluminum construction is robust and non-corrosive, with a sleek anodized finish that complements your vehicle. An integrated, magnetized cable lock pulls out of the rear to secure your frame. Locking the rack itself, Rocky Mount offers separate locking cores (not included). The Switch Hitter securely carries bikes with 9mm quick-release front skewers and modern thru-axle standards, with the included 9mm quick-release skewer and separate sleeves for 12x100mm, 15x100mm, and Boost 15x110mm thru-axles. The ratcheting rear wheel strap accommodates a variety of bike sizes by sliding along the carrier. Also, it's compatible with tires up to three-inches wide, should you need to transport trail bikes with plus-sized tires.
