FSA KFX E-Bike Crank Arms for Bosch Gen 4 / Yamaha / Fazua - ISIS - CK-9011/IS - black

FSA's KFX range represents a selection of lightweight and stiff MTB components. The super-light KFX aluminium crank arms are created through an innovative manufacturing process that drastically reduces weight while increasing stiffness. The clever hollow construction of each crank arm is based on two separately forged blanks that are precisely CNC-machined and then joined together using an advanced bonding process. The result is a tightly interlocking single piece for a crankset of professional top level. The CK-9011 crank arms are equipped with an ISIS mount and suitable for E-MTB's with drivetrain systems from Bosch (generation 4), Yamaha as well as Fazua. The Q-factor and maximum distance from crank arm inside to crank arm inside depend on the respective drivetrain. Q-factor / crank arm inside distance: Bosch: 173 mm / 143 mm Yamaha: 164 mm / 134 mm Fazua: 171.5 mm / 141.5 mm Weight: approx. 350 grams (pair, manufacturer's specs)
