I always wanted a set of the XTR cantis when they were the thing. Picked up 3 wheels worth the other day for $30. Two wheels worth even had new Ritchey pads! (my favorite brakepad).
Mounted them up and I'm as impressed with them as I'd hoped I'd be : )
I'm guessing these are about 94 vintage xtr's, but they might be as late as 96's.
Mike, I just file the first 1/32" off the backing nut and use them stock. Everything bolts right up and tightens down correctly. Took about 5 mins with a flat file to cut all the backing nuts down.
I was about to order a set of single ring fixing bolts, then I decided to measure the stock Shimano parts. They were just a few thousandths too long to fit, so a few passes of a file allowed me to save another $15 on the project.
