A great retro bike Ned. Briefly, what is the theory behind those cranks? I like the cigarette paper clearances too. Yot have got to think about tight corners on that puppy.
There was a discussion on here recently about them, can't remember where. Basically there isn't any advantage mechanically, the distance from the crank centre to pedal hole centre is still 170mm (or whatever length they maybe - up to 180 I think). It's all marketing hype (ie b*llsh*t!) - but they look good and always raise a comment or two. Very sought after in the right circles.
I think I can only use 170 cranks on this as anything longer would lift the chain as the right hand crank came up when on the smallest sprocket. The chainstays are very short and I can catch my heel on the gear mech at times.
About clearances - there aren't many tight corners on dual carriageways
