That kinda clip-on cover is still around in bike polo circles.
I always lusted after one of the Tioga (Sugino) Disk Drive wheels back in the day, in a kinda small-boy form over function kinda way.
Be quite a rare find now I'd have thought, given the death-rate amongst them, and their relatively short product lifespan (doubtless linked to the death-rate).
(Hmm, heads off to ebay to look anyway).

The real deal:

I used to have a cover for my old 'time trial' bike back when I was a juvenile.
Weighed in all at a bloody ton, but at 15 it was all I could afford - still took an average of 1.5mins off my 10 mile time though!
I remember seeing and hearing them at my first ( and penultimate) XC race at the sports grounds in Southampton in '89, they sounded harsh and heavy to me and I was totally besotted with my Bear Valley to find them anywhere near enough desirable, when there was so much ano purple stuff, girls and partying to spend my disposable and in disposable income on.. 😀

Revolver (and Cosmic!) predated the Tioga disk by a few years, IIRC.
Tushingham 8)
Mainly from back in the day when I used Tushingham and Orange Sails. And the first MTB I ever rode was a clockwork up the hill and a B52 back down...
it was all about the stems back then - everything else was just window dressing
I bought a tioga disk drive pro the week before last. Wheel build underway onto an xtr hub. I know it isn't something I can ride hard, I had one on my amp B3 years ago and sure enough it didn't last long but for those who've been riding for many years they are iconic history.
I remember Dave Hemming with one at Malvern, sounded like a washing machine on the blink!
