Twin disc conversion
It’s looking more and more like I’m going to have to put a twin disc set up on it. I’ll probably get a marching PFM full-floater for the other side. I seem to recall that the hub had a cover on the left side under which were the holes to bolt a disc to. Can it really be that easy? Nothing else is!
Whilst I’m doing it, I’m very tempted to go with cast wheels. I think they’d be more in keeping with the theme of an ’80s race bike. What are my options here? Is it possible to get a 19” cast wheel? What styles did they come in?

Fabulous.
As the eagle-eyed will see, I never did fit a twin-disc conversion. What I did do was fit a Harrison Billet 6 instead. It’s got a PFM, full floating disc and Brembo RCS 18 20 radial master cylinder, so it should be enough. I seem to recall it weighed in at under 160kg
