Rotor Cranks eKAPIC Brose qf170

• With eKAPIC crank arms, mountain bikers are one step closer to the dream of a lighter electric bike.
• In order to achieve a construction specially adapted to E-MTBs, Rotor has specifically developed the design and technologies of its proven MTB crankarms.
• Trinity Drilling System. Three holes along the longitudinal axis of each arm remove excess material.
• The TDS process significantly reduces the weight of cranks made of forged and CNC-machined aluminum, without negatively affecting rigidity.
• Narrow Q-Factor.
• When it comes to climbing hills, the eMTB clearly shows its strengths, but it is generally at a disadvantage compared to traditional bikes when it comes to pedaling feel.
• By making the Q-factor for e-bikes as narrow as possible, Rotor has not only addressed this problem, but is also actively helping to prevent biomechanical damage during off-road riding as well as hip and knee problems.
