quick and easy
20 seconds on the rack and 20 seconds off the rack. the clamp arm is adjustable and secure. 85 mph with a bike on the roof and no worries. i dont think i agree with the "high security" comment in the description though. i have thrown a cable lock on it to grab something to eat, but i am still nervous my rig will get jacked. the best thing about it is that its easy, fast, and works great with my hardtails. dont own any full suspension bikes so i am not sure it would be good for those silly things.
