Not sure about the flex stem either tbh. I like the way it smooths everything out, but it look's pretty ungainly. Going period XT on the drivetrain and shifters, headset is the only thing that's DX, so it is a bit of a departure from standard spec.
Kaiser - I've got a set of 730 cranks that I'm going to polish up, but they're 170 rather than 175, and I'm not sure what effect (if any) that's going to have when it comes to pedalling. Wotcha got? As you know, not hugely worried about period correctness, as long as they look right...
