FSA E-Bike cranks CK-745/IS armset 165mm

Product description

FSA E-Bike cranks CK-745/IS armset 165 mm

The FSA CK-745/IS cranks are designed specifically for e-bikes with BOSCH GEN4 motors, where your performance is enhanced by electric support. Forged, solid and ready to use.

When the engine is working under your feet, the cranks are one of the places where all that power comes together. That's why you have a forged aluminum construction that's built to handle that kind of load for the long term.

The crank arms are forged from AL6061/T6 aluminum alloy. The forging gives the material a dense, strong structure, so the cranks can withstand the stress of electric assistance while maintaining a reasonable weight of 477g for the entire set.

The proven ISIS Drive splined connection ensures a firm and precise fit of the cranks on the motor shaft. The power transfer is direct and without play, so you feel every pedal stroke on the bike as it should be.

The 2-Tone finish gives the cranks a modern and understated look that matches the clean lines of the e-bike drivetrain.

The 165mm crank length is suitable for riders who want a shorter lever, easier pedaling off-road and less risk of hitting an obstacle when leaning.
