The new KAPIC Carbon from ROTOR is billed as the lightest and stiffest crankset ever at 429g (175 mm, 32t w/o BB). According to the company, it has been developed in response to cutting edge bike designs of the modern MTB rider, ‘to withstand the most demanding riding conditions with an incredible result in weight, strength and rigidity.’
ROTOR notes that it has ‘created an exceptionally light crankset to meet the highest demands of pros, from the explosive pedal power required at World Cup circuits to the endurance and recovery riding of the epic marathon stage races.’
The carbon edition of the KAPIC crank family is inspired by the 7 historic victories of ROTOR athletes at the legendary Cape Epic where the world’s elite riders attempt to cross the savage beauty of Africa’s off-road trails. KAPIC Carbon was tested to the limit in its World Cup debut with elite riders from Primaflor-Mondraker-ROTOR, Absolute Absalon, Specialized Racing Team and CST Sandd Bafang under some of the toughest MTB conditions at Albstadt and Nove Mesto.
ROTOR adds that manufacturing cranks from carbon fibre complements the evolution of wider MTB bike frames, which require a very sharp opening angle of the cranks with respect to the axle. The company worked to get a precise mix of lightweight carbon fibre material. KAPIC Carbon is available for both Boost and Super Boost chainline options in 165mm, 170mm and 175mm crank lengths.
In the fusion of carbon and aluminium at the axle joint and pedal fitting, ROTOR ‘tested countless carbon fibre models using a meticulous development process to reinforce the hardest wearing elements of the crank using ROTOR Carbon technology.’
KAPIC carbon is the latest addition to ROTOR’s Direct Mount technology family that features a proprietary spline interface connecting crank arm, axle and chainring. This allows for simple assembly and disassembly of the crankset. Modularity allows riders to select their preferred chainring size for each ride – with the removal and installation of the chainring via only one bolt.
The OCP mount technology with Q RINGS allows riders to adjust their Optimal Chainring Position (OCP) and configure a unique OCP for maximum power output distinct to pedalling style. Riders can customize and protect crank arms with rubber bumpers in a choice of seven colours: black, blue, green, yellow, red, pink, or orange.
