If you're riding a bike with a 20mm thru axle, or a full-suspension mountain bike, or even have kids bikes without a quick release front hub, the T2 makes loading bikes easy and ultra secure.  The T2 now includes a STL2 and 2 One-Key lock cores so you can lock the bikes to the rack and lock the rack to the vehicle.  This upright mount hitch bike rack is the perfect solution for your rear mount bike rack.  This rack only fits in 1¼" hitches.
