Guys I turned my Bianchi San Jose into a 7 speed. Singlespeed was cool, but I would rather wreck my knees during ski season. My LBSput an ultegra bar end shifter on friction mode, and paired it with a sram chain, campy mirage long cage derailleur, and shimano 7speed freewheel (13-34). Gotta say, the thing is as quiet as when it was only a single speed!
let me know if the link works
