I have a CC that is my primary ride; commuting every day, and occasional fun rides.

At first (right now) it is built up with tiagra 3x8 from a donor Trek. But I'm just about to convert it to 2x9; the C&V part is that the "2" will be this 600 crankset:



(I have had that 600 crankset laying around since it came off that bike in favor of a Record crankset I picked up)

The rest of it will not be too C&V -- except perhaps that instead of STI I'll have Retroshifts. That gets me barcon brownie points, right?
