XRAY NT1 Performance 21T Clutch Gear by Arrowmax AM-NT1-338521  [AM-NT1-338521]

CNC 21T Clutch Gear Designed for XRAY NT1

Engineered for the XRAY NT1 range, the Arrowmax AM-NT1-338521 21T clutch gear is CNC finished for reliable geometry and repeatable performance. The component is crafted from 7075-T6 aluminium to combine toughness with a low mass profile.

Stiff and Lightweight Aluminium Build

The 7075-T6 aluminium offers a high strength-to-weight ratio, reducing rotating mass while retaining resistance to deformation during heavy use on track.

Consistent Meshing with Spur Gear

This 21T profile is produced for accurate engagement with XRAY NT1 spur gears, smoothing power delivery and limiting uneven wear when the drivetrain is correctly shimmed.

Multiple Tooth Options for Ratio Control

Available across a selection from 16T to 23T, these clutch gears enable precise gearing adjustments to suit different circuits and motor characteristics.
