KCNC's Blade chainring series offers a departure from standard chainring design. These flat and aerodynamic rings make no comprises, with weights very close to KCNC's standard chainrings and similar performance as well. In the manufacturing process, KCNC starts with a thin 7075 aluminum sheet and boldly machines the inside to the least possible thickness, while leaving enough material to retain stiffness and provide sections for shift ramps. These chainrings are also equipped with durable steel shift pins to further aid chain movement from small to large ring. Blade mountain rings are available in triple configuration for 104/64 BCD 4-bolt cranksets, or in double configuration for 94 BCD 5-bolt cranksets.
KCNC's 29 and 42 tooth Blade chainrings are compatible with 2x9 drivetrains with 94 mm BCD cranks, while the 22, 32, and 44 tooth rings are compatible with standard triple 104/64 mm BCD cranks. Installation will require tools for removing chainring bolts and crank removal tools if the crankset to be fitted is currently installed.
