The XRAY 375880 Composite Spur Gear is designed to keep drivetrain drag low while providing predictable power handoff. Its 80T/64P specification is common in race builds looking for fine-tuned ratio selection.
Using composite lets the gear resist impact and surface wear without significantly increasing mass. That results in better throttle response and less rotational inertia compared with heavier materials.
Produced to consistent mould tolerances, the XRAY 375880 fits with standard 64P pinions. Set gear mesh carefully and recheck after a few laps to ensure stable contact and quiet operation.
