Inspired by the six victories of our athletes at the legendary Cape Epic, we thought it was only appropriate to name our lightest and stiffest crank ever after our most successful mountain bike race to date — and thus the ROTOR Kapic was born. Arguably the most prestigious marathon stage race, the Cape Epic sends riders into grueling, rocky climbs, forested singletrack, and rock-laced descents that require a crank that delivers stiffness and control that won't waiver under pressure, and we've crafted the Kapic to do just that.

Much like our popular Hawk Crankset, the new Kapic is designed with an innovative modular system that allows you to select each crank component individually, based on your unique bike setup and your own physical characteristics. It features the same spline interface as the Hawk, so you can utilize the strength of Hawk chainrings, but combines with a weight-saving Kapic spindle to lighten your ride, and lighter crank arms for almost a half-pound of weight savings when compared to the Hawk.

We designed the Kapic with Direct Mount technology that features a spline interface that connects the crank arm, axle, and chainring, allowing simple assembly and disassembly of your crankset. This enables you to choose the perfect chainring size for each ride, and easily remove and install a chainring with a single bolt. But the versatility of Direct Mount doesn't stop at modularity, it also enables us to employ Optimal Chainring Positioning (OCP), which, when combined with a Q ring, allows you to adjust your chainring position a single degree at a time to precisely configure your crank for maximum power and comfort.

Crafted using expert CNC processes, KAPIC is built from 6082-aeronautic-grade aluminum, and includes our Trinity Drilling System, with three internal holes from axle to pedal, giving the dual benefit of an exceptionally light crank with superior stiffness to handle the toughest of MTB routes.

The Kapic has been designed to mirror the strength, agility, and speed of Africa's fastest land mammal, so you can soar down the singletrack like a cheetah sprinting after its prey. To pay homage to the home of the race, we gave the Kapic bold aesthetics and iconic patterns that symbolize the geometric designs of tribal Africa.

Weight: 365g (170mm arms only), 545g (170mm crankset, boost axle, 32t chainring, and boots)

- Ultralight, modular 6082 aluminum arms with exceptional stiffness to weight ratio
- OCP direct mount rings allow the rider to configure to their optimum chainring position for maximum power transfer
- Axle spindle, spacer, DM ring, and bottom bracket options are available separately
- Due to the inset bore location of the pedal threading, some flat pedals with a large inboard bearing may not be compatible with the crankset or crank boots
