I must admit, I like the ease with which the rear wheel can be changed. It is fast compared to other systems. I once had to repair a puncture at a garage up the line from us and the owner of the garage was surprised how quick that wheel came off. He rode a Harley.
That later Cush drive above is certainly a better looking solution I must agree,.
I tried the rubber grease on the Cush rubbers but it was still a pain. I'm happy with grinding off those high spots, as it does make the job a lot easier. So what if they don't last that long, they are not expensive to replace, but I have not needed to yet and I think I have done about 20,000 miles on the new ones.
I presume with that later Cush drive shown above that the bolt goes through from the left hand side and stays in the brake hub when changing the wheel.
