FSA E-Bike CK-745 ISIS crankset 165 mm

Description

When your power and the electric assist come together on the pedals, you want confidence and peace of mind under your feet. FSA E-Bike CK-745 ISIS cranks 165 mm keep up on climbs, gravel, and technical sections. Every pedal stroke feels solid and natural, without any unwanted play.

Main benefits

The crank is built for e-bike loads, where the rider’s output adds to the motor’s power, so the focus is on long-term durability. The forged construction withstands repeated impacts and high torque.

The ISIS Drive interface creates a precise splined connection that keeps the cranks stable on the spindle. Power transfer is direct, so energy isn’t lost to side-to-side movement.

The 165 mm arm length helps reduce the risk of the pedal contacting obstacles when leaned over in terrain. The shorter leverage also supports a quicker cadence when climbing.

The 2-Tone finish looks modern while subtly matching the clean lines of an e-bike. It doesn’t overpower the rest of the components, but keeps a consistent style.
