Spider – Crank Spiders & Chainring Mounts

Crank spiders and chainring mounts for bicycle cranksets and e-bike drivetrain systems. The spider provides the connection between the crank arm and chainring, making correct compatibility between the crankset, axle system, chainring and drivetrain essential.

Our range includes spider solutions for road, MTB, gravel and e-bike applications, including products from FSA, SRAM, Shimano and other leading manufacturers. Available designs include traditional 4- and 5-arm spiders, BCD, Direct Mount and specialized solutions for e-bike motors and drivetrain systems.

For e-bike applications, the correct chainline is particularly important. Chainline determines the position of the chainring in relation to the cassette and rear drivetrain. An incorrect chainline can lead to increased chain wear, drivetrain noise and poor shifting performance. Some e-bike systems require specific spider designs and chainline positions based on the motor, frame and rear axle standard.

When selecting a spider, it is important to check the BCD, Direct Mount standard, axle type, crankset design, chainline, chainring tooth count, number of speeds and e-bike motor compatibility. The correct spider ensures proper fitment and an optimized chainline for reliable drivetrain performance.
