theres only a couple of problems in using a sprung hub, the cost of the bearings and their availability is rediculous , & NEVER take them apart unless you use a safety cage !!!, the springs have been known to cause serious injury & harm if ya have never done one, but i'm guessing it ain't ya first race,
the 'Tuffnol' mag drivegear was a great idea, it has saved many an expensive repair,
i used it a lot at college as a medium to practice on Lathes & Mills so ya didnt ram the tools in when learning, I ended up making several mag gears out of it & the gear cutter, made a prett penny on them 40+ years ago, a manufactred weak spot would be handy on many mag fired motors Harleys included....
