<< there was an American builder who's name escapes me, building in the 70's, that fabricated the chainstay bridge as a section of tube that pierced both stays and terminated at the outside. One could see through the bridge. Was for additional stiffness the owner told us, a few months later He was by the shop with the bare frame seeking a frame repair at the cracked stay radiating from the piercing tube. Probably too big a hole in that case, and easier to prototype than do a structural analysis. Perhaps the price of advancement, or attempt to. >>
