Campagnolo Bora Ultra 11-speed crankset, 170mm, 53/39T – new in the original retail box. The Bora Ultra sits at the top of Campagnolo’s crank lineup, pairing full carbon arms with the Ultra Torque titanium spindle system for a stiff, light interface that’s a step above the standard Record/Chorus carbon cranks. The 53/39T standard chainring setup covers road and TT use, and the titanium spindle bolt uses a left-hand (counterclockwise) thread – worth knowing before you build it up. Chainring is stamped with the low serial number SN 0033. New, unused, in the original Campagnolo retail box with all factory labels and warning stickers still attached. No signs of use – this has never been mounted to a bike. As with any Campagnolo Ultra Torque crank, the frame-specific cup shells BSA, PF30, etc.
