Important Product Information

Trek’s product record identifies this as the complete spider and 50/34T chainring assembly. It also specifies that this configuration is supplied without the separate pin.

Compatibility

Intended for compatible Fazua e-bike systems requiring the FSA W0005 spider, 110 BCD mounting, a 50mm 2x chainline, and 50/34T gearing. Fazua systems use more than one spider and BCD standard, so motor brand alone does not guarantee compatibility. Verify the spider model, motor interface, chainline, drivetrain, and Trek OE part number 598559 before ordering.
