Industry Nine Rear Bearing Kit

This kit is specifically designed for the Industry Nine 1/1 MTN hub with a Micro Spline freehub body. If you are unsure of your hub model, check the laser-etched markings on your hub shell or consult your wheelset's original specifications.

Yes, this is a complete replacement set. It includes two 15307A3 bearings, two 61802A3 bearings, and one 152610A3 bearing, which covers all the necessary points for a standard rear hub overhaul.

These are high-quality steel bearings. They are factory-spec components chosen for their balance of durability and smooth rotation in demanding trail conditions.

If you have a bearing press and the appropriate drifts, you can perform this service at home. However, because bearing installation requires precision to avoid damaging the hub shell or the new bearings, we recommend using a shop if you do not have the proper tools or experience.

Factory-spec bearings are engineered to the exact tolerances required by Industry Nine for their specific hub designs. Using these ensures the correct fit and maintains the original drivetrain engagement feel that aftermarket alternatives might compromise.
