Just bought an '04 Colonel 29er and need some new tires. Also decided to go with a new wheelset from Mike C. (VXC's with 240's). On my old wheelset I was running a Nano on the rear wheel, but didn't have a whole lot of clearance to work with. I'm talking less than 0.25 inches b/t tire and seatstay and b/t tire and base of monostay. What about the new Karma's? Any other suggesions?
