Lightweight 18T Pulley for XRAY NT1 Drive Train

This 18T aluminum pulley by 3Racing is tailored for the Team XRAY NT1 to deliver crisper power delivery and reduced wear. The aluminium body balances weight savings with structural strength to suit demanding track sessions.

Why Fit an Aluminum Pulley?

Switching to aluminum lowers rotating inertia while keeping the pulley stiff under load, which helps the XRAY NT1 maintain consistent drive under acceleration. The 18T profile aligns with NT1 mounting points for a secure installation.

Does this replace the stock pulley directly?

It is designed to be a direct physical match for the NT1 pulley position, though confirm your specific build and shaft fittings before swapping parts.

Is the finish corrosion resistant?

Aluminum resists rust but check the surface treatment and keep components clean after wet running to preserve finish and fit.

Will this affect gear ratios?

The pulley maintains the same 18T tooth count, so it does not change ratio compared with other 18T parts, but it can improve drive feel and consistency.
