Perfect for 2
This rack is perfect for 2 mountain bikes, diamond back Overdrive 29'er and a GT Avalanche. I think the fit is tight on a 2" hitch, the threaded bolt needs a 7/16 spanner or ratcheting socket wrench. The threaded bolt really sets the rack tight and stops any wobble. It takes about 30 seconds to put the rack on your car and probably 5 minutes to get your bikes on. The anti-sway bike cradles are stiff and hard to move and the rubber straps can be hard to undo. Great rack though and I trust my bikes on it.
