It's going to be 2x9: A mishmash of DA/Ultegra/105 nine-speed. The crankset I have is a standard 53/39 but I think if I replace the 53 with a 48 (just ordered one from Ben's Cycles), that should be okay with 12-27 in the back. The wheels are Ultegra/Open Pros, Tektro CR 720 cantilevers.
The question will be tires. I have some Kenda Kwicks from when I tried to jury rig my Trek SS, but I wasn't crazy about them. Any recommendations for the local courses?
