AC Cranks And Boone Chainring For Sale

Time to let this nice chainring/crankset combo go! Originally, I bought the Boone ring for my Niner build. Wanting a tight Q-factor, I combined the chainring with a hand-polished and black-anodized XTR crank bolted to a narrow Dura-Ace BB. Nice idea, but it didn’t fit. Well then, it would just go on a Kelly that I was rebuidling. Got a wider Shimano BB for this frame, and once again, it didn’t fit. The Kelly had straight chainstays and the flat Boone ring had no clearance. So, here we are with a super-sweet chainring on a crank you don’t see often these days and no bike to put it on. If you got one, here’s your chance to get these parts some action.
