Setup-Oriented Brake Pulley for Competitive NT1 Use

The XRAY NT1 21T brake pulley by 3Racing, model XN1-47/RE, is produced with a focus on racing setup refinement. Its 21-tooth configuration changes mechanical leverage to offer tighter modulation and more controllable bite, which helps when tuning brake bias for different track conditions. Fitment is intended for NT1 chassis geometry and the part supports repeatable pedal feel for precise driver input.

How does the 21T pulley interact with brake-centre adjustments?

The increased tooth count refines leverage, allowing finer steps when adjusting brake-centre; small changes result in measurable differences to bite.

Should I change pad material when fitting this pulley?

Pad choice remains important; evaluate preferred pad compounds on-track and use the pulley to tune modulation rather than compensate for an incompatible pad.

Any recommended checks after installation?

Verify axial alignment, ensure free rotation without binding, and validate brake travel through progressive bench and track testing before full race use.
