KCNC: K3-Type RD Crankset
The latest K-Type lightweight double road crankset from KCNC, featuring cobweb chainrings. Fully precision CNC machined, with external stainless steel bearing bottom bracket (ceramic upgrade available).
These cranks are exquisite, weighing in at just 727 g complete (175 mm 50/34). They also have a reduced Q-factor of 151 mm.
The new bottom bracket design features full stainless steel replaceable cartridge bearings (ceramic upgrade available) 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.
