FSA CK-320 ebike chainset in black, with a 27.5mm Bosch interface and 170mm crank arms, in stock for click and collect or fitting in Kennington.
The FSA CK-320 is an ebike-specific chainset with a 27.5mm bottom bracket interface for Bosch motor systems and 170mm crank arms, finished in black. The two numbers that matter here are the 27.5mm interface, which decides whether it mates to your motor, and the 170mm arm length, which sets your pedalling circle, so it is worth checking both against what is on your bike now.
Ebike chainsets deal with higher torque loads than standard ones, and this is built to stay durable under the extra power coming from the motor, which suits regular commuting and leisure riding. It is a replacement chainset rather than a full drivetrain. We have it on the shelf in Kennington for free click and collect, and our mechanics can fit it for you the same day.
