Industry Nine 1/1 MTN Bearing Kit

No, this specific kit is designed exclusively for Industry Nine 1/1 MTN hubs. It is compatible with both HG and XD freehub body configurations, but it will not fit Hydra or Torch series hubs.

Yes, this kit includes the complete set of replacement bearings required for the 1/1 MTN rear hub. It comes with two 15307A3 bearings, one 15267A3 bearing, and one 152610A3 bearing.

Yes, replacing hub bearings requires a bearing press and appropriate drifts to ensure they are seated squarely without damaging the hub shell or the bearings themselves. If you are not comfortable with precision mechanical work, we recommend having a professional shop handle the installation.

You should consider replacing your bearings if you feel gritty resistance when spinning the wheel, notice lateral play in the axle, or hear audible clicking or grinding noises while riding. Regular maintenance intervals depend on your riding conditions, but wet and muddy environments will accelerate wear.

These are high-quality steel bearings. They are engineered to meet Industry Nine's factory specifications for durability and smooth operation in mountain biking applications.
