Hulsroy's Hustle

I didn't mean the fork - I wouldn't braze anything except eyelets onto an old fork to be honest, including canti studs. New fork would be required either way methinks. But I don't really know anything so take that with a pinch of salt.

Cable disk calipers are cheap, 6-bolt QR wheels can be had cheap and overall it'll brake 30× better than cantis. But yes, you won't be able to do it for £30 or whatever if that's your budget.
