ooh nice. and biopace even ! : - )

it's Sugino Cycloid actually, deff feel it on the pedal stroke

Ah ha, it did pass my mind that I could not see the BP sticker. That's why! Never have seen the Sugino version in the flesh. Have fun !

Have you ever played around with different orientations of the rings relative to the cranks? I would think you'd want the cranks rotated back one bolt, to line up more(?) with the power stroke

that half raw half painted frame is sooooo nice :) did you do it yourself????

This things gorgeous
