Do any of you old schooler's remember Promag II mags by Coates Industries? Made in NZ in 1980. I've been carting these around for quite a while looking for the right bike to fit them to. I think they work quiet well on a Repco Monoshocker.
The front is a loose ball with cups that press into the wheel, the rear uses a Shimano MX coaster brake. Cast alloy, heavier than a Pantha mag!
