Specifications

Q: Is this the official "BB30 Bearing"?

A: Yes. In the cycling industry, when a component or frame requires a "BB30 Bearing", it is referring to the 6806 model with 30x42x7mm dimensions. They are one and the same.

Q: What is the difference between BB30 and PF30 (PressFit 30)?

A: Both systems use the same 6806 bearing. The key difference is how the bearing is installed. In a BB30 system, the 6806 bearings are pressed directly into the frame's bottom bracket shell. In a PF30 system, the 6806 bearings are first placed into a nylon or plastic cup, and then the entire cup assembly is pressed into the frame.

Q: Do I need a special tool to install or remove these bearings?

A: Yes, absolutely. Due to the press-fit nature of the BB30 system, you must use a bearing press tool and a removal tool specifically designed for BB30 to avoid damaging the bearings or your frame. We always recommend professional installation.

Q: Is this bearing compatible with my SRAM or FSA BB30 crankset?

A: Yes. This 6806 bearing is compatible with all cranksets that are built to the BB30 spindle standard, including those from major brands like SRAM and FSA.
