Used C-Record Italian threaded bb for double crankset. Very good condition, with bearings coated with Campagnolo grease--I didn't clean it when I removed it from the frame. No crank bolts as the C-Record are part of the crank. I will include a set of non-Campagnolo crank bolts if you need them. I think this will fit NR/SR. $28 shipped. Return if not happy with it.
