This ball bearing set is specified for use with the Team XRAY NT1 chassis and carries the model number BS-XN1/V1. It is intended as a service replacement to support drivetrain shafts and wheel mounting points on the NT1 platform.
Designed for competitive setups, the bearings reduce rolling resistance and help sustain alignment under dynamic loads. Prior to installation, verify seat diameters, clean mating bores, and inspect related components for wear or deformation to ensure accurate seating and long life.
Workshop notes: use a press or appropriate driver to install bearings square to the bore, avoid applying force to inner races, and confirm differential and hex clearance after assembly. For maintenance focus on contamination control, regular inspection of races, and prompt replacement when roughness or play is detected.
Engineered as a straightforward replacement for NT1 drivetrains and wheel assemblies, this set supports low drag and consistent bearing behaviour in race and practice environments.
