Welcome to the new and improved Proflex / K2 Tech Forum!
(slight highjack here) Terry, I just had a friend sell his Serotta softtail. You didn't get it off Ebay from Mi. did you? I just sold off a Schwinn Moab that had the 22mm rear mount. It was a PITA to get adjusted. I had to file the base of the caliper to get it to line up. It was great when I finally got it aligned though.
I seriously can't understand how someone could pay $3K or more for some of the bikes available these days. I picked up my 4000 for $400, upgraded it to slightly used XTR (M950 series) for another $250 and now have a better bike than most in the $2000 range, IMO. - Doug :-)
