ROTOR crank arms eKapic Bosch Gen 4 E-Bike | black
With the eKapic crank arms, ROTOR is launching the lightest crankset for e-bikes in the company's history. The low weight of the crankarms is achieved through the Trinity Drilling System technology in conjunction with the use of direct mount chainrings. eKapic crankarms are also characterized by their enormous stiffness. The crank arms have rubberized crankboots to protect against stone chips.
Trinity Drilling System technology
Minimum weight and maximum stiffness at the same time? Rotor's Trinity Drilling process makes it possible. The crankarms have three carefully calculated holes drilled through the "neutral fiber" of the crankarm. This makes the crank arms real lightweights without compromising on stiffness.
