KCNC: K3 XC Double Crankset


The latest crankset from KCNC featuring KCNC’s External Bearing Bottom Bracket (K-type) and new cobweb chainrings. At 714 g, complete, it’s one of the lightest cranksets available!

Complete with anodised alloy chainring bolts that are also available in Gold, Red, Blue, Green and Silver.

The new bottom bracket design features full stainless steel replaceable cartridge bearings and a red alloy spacer clamp to remove axial float of the scandium alloy axle. The crank arms are both removable from the BB axle, but the new design allows the driveside arm and spider to be left on the axle, and the axle to be removed by simply removing the non-driveside arm and sliding out of the BB. The non-driveside arm is supplied with a stainless steel extractor cap.
