Race-ready 68-tooth spur for X12 drivetrains

The XRAY 375868 Composite Spur Gear is tailored to the X12 range, with a 68-tooth, 64-pitch layout that balances toughness and precise engagement. The composite build reduces rotating mass while maintaining the stiffness needed for repeatable lap times, making it a practical upgrade for those refining their drivetrain.
Remark :
Due to limited stock availability, please notice that some XRAY items may have to order from the factory and the ready time is around 4-6 weeks. Customer purchases the item is assumed to accept the waiting time which allows us to order directly from the manufacturer if the item is out of our warehouse.

How do I check for proper mesh on this spur?

Fit the pinion, set a small clearance with a gauge or card, tighten the pinion set screw, then rotate the drivetrain to confirm smooth teeth contact across the mesh.

Are there specific pinion sizes recommended?

Pinion choice depends on track and motor; pair any 64-pitch pinion that gives the desired ratio, and always check motor temps and ESC load after changing gearing.

Will this reduce drivetrain noise?

Composite spurs tend to run quieter than some metal options when mesh is correct, helping reduce gear whine without sacrificing engagement quality.
