Hey, some feedback....
Ok, I finally got the UCM on my 36-er, it fits great and as soon as I get a rotor that's not tweaked, I'll be able to better test it

One thing about the whole system, you may want to find a source for 1mm crank spacers in the form of washers or something. I finally have my set up dialed in where there is no disc rub but the tolerances are so close that the crank is rubbing ever-so-slightly on the caliper. I plan on just grinding the crank down a little bit. It won't make them weak, I think this could have been remedied if we had a 1mm washer that fit into the system. What do you think?
