I'm using a Shimano UN73 107mm BB with some old Shimano 600 cranks, chainring on the outer position. Or should I say I *will* be, once I get this thing built. The crank & BB are installed and the chainline looks like it'll be perfect. I just ordered by wheel parts from Harris yesterday: Harris hubs, Mavic CXP-33 rims, DT Competition spokes. Everything is silver.
Got a set of jagwire cable guides coming, too.
