81 CUSTOMS PRO B LOK CLAMP BLACK Introducing the brand new B-lok clamp from 81 Customs The B-Lok clamp was developed after witnessing a number of accidents whilst watching people on Scooters. The simple fault with most collar clamps is that they are placed over the bars and then tightened. This means that the rider is relying on the pressure from the clamp through the bars to stop the bars from coming off. So what happens when the clamps loosen? You guessed it the bars come off. Just suppose you where flying of a ramp at the time? This is why the new B-Lok eliminates this risk. The B-lok clamp (PAT pending) has been fully CNC machined and fitted inside with a thread. This thread is then aligned onto your scooter forks and tightened. The bars are then placed into the top and slide over the forks inside the clamp. Once tightened there is approx 60mm of coverage over the bars. The clamp cannot come off of the scooter as it becomes part of it. The B-Lok fits JB Bug, Razor Ultra, MAdd and more
