XRAY NT1 19T Pulley Aluminium Upgrade - XN1-41/RE by 3Racing  [XN1-41/RE]

Aluminium 19T pulley tailored for NT1

This 19T aluminium pulley is designed as a drop-in replacement for the XRAY NT1 belt-drive arrangement, keeping the chassis mounting points intact while offering improved belt contact and alignment. It is sized to match standard NT1 installations.

Installation follows standard NT1 procedures: remove the original pulley, place the XN1-41/RE on the same hub or shaft position, then recheck belt tracking and correct tension. No chassis alterations should be necessary; follow the NT1 service guidelines for fastener retention and torque settings.

Consider this pulley as part of setup and upkeep rather than a major drivetrain change: aluminium helps keep consistent alignment during fine tuning and integrates with usual NT1 checks such as belt tension, pulley runout and bearing condition.
