So while I'm waiting for my brake hoses to come I've got a few other things to work out.
XTR brakes also had the shifter mount integrated with them (really should have thought about that) but I've found some random Sram clamp in my spares box that I think will work. From what I can tell there are no shifter mounts available yet, here's what I've got.
I also think I'll take the Magic Mary off the front and save that for a tractor if I ever buy one, and put the Hans Dampf up front.
Suggestions for a rear that's light and fast rolling? I was thinking Michelin Force AM? Bearing in mind that I'm old, half blind and don't race downhill so I have no need for a Minion which is the default answer on this forum.
