XRAY NT1 Brake Pulley 21T Upgrade XN1-47/RE by 3Racing  [XN1-47/RE]

Component Brief

Designed as a scale replacement for Team XRAY NT1 brake assemblies, this pulley is supplied under part number XN1-47/RE. The 21-tooth component installs in place of the original pulley to help preserve consistent braking action and let hobbyists tweak pedal response.

Installation guidance: perform a standard teardown to remove the old pulley, check the related 走珠軸承 and brake arm for signs of wear, confirm alignment with the cable or linkage, and secure fasteners to the correct tension without over-tightening. This product is for model use only.

Tuning role: replacing the pulley affects how brakes engage and their repeatability across laps. Use the new pulley to refine lever geometry and linkage play, and combine the swap with routine bearing cleaning and light lubrication for steady behaviour.
