Review on NRG Innovations SRK-200BK Quick Release (Black Body/Black Ring), gen 2.0: Enhanced Quick Release System for Effortless Steering Control by Inyong Dow

Very easy to fit (I bought an NRG hub and steering wheel) and even easier to use. Just make sure you turn the steering wheel about 90 degrees after removing it from the hub so that the ball bearings are covered after the steering wheel is removed. Just push the button, pull the handlebar out and then rotate it 90 degrees (or less) to the opposite side, then push on the handlebar (it won't line up properly) and pull again. You will feel a shock that closes the ball bearings and prevents dust or dirt from getting inside.
