I have washed my hands of this italianness after a morning of head scratching and lack of BB tools. Also the NDS crank arm won't come off. Thread gave way first. I will go woth a sugino trple on the front and ultegra mechs.
The wheels are presumably useable with shimano non indexed shifters so that is the way forward. Everything else will be offered as parts. If I can get them off.
Any shorter and there’d be interference with crank and shell. Innovative don’t you think? Braze mech was too high for my mtb cobbled together crankset.
