Wheels Manufacturing BB86 To 30MM Bearing

Yes, these bearings are specifically designed to bridge that gap. They allow you to run a 30mm spindle crankset in frames with a 41mm internal diameter bottom bracket shell, such as BB86, BB92, and others.

Yes, these are sold individually. You will need to purchase two bearings to complete the installation for your frame.

Yes, for a proper fit, your crankset spindle length must be longer than 104mm when installed in an 86.5mm wide bottom bracket shell. Always verify your spindle length before purchasing to ensure compatibility.

These dual-row ceramic hybrid bearings are engineered for reduced friction and increased durability. They offer a smoother rotation compared to standard steel bearings, making them a great upgrade for high-performance cycling.

These bearings are designed for a direct-fit installation into 41mm internal diameter shells. Because they press directly into the frame, you generally do not need additional adapters, provided your frame meets the 41mm specification.
