Wheels Manufacturing BB86 PressFit Bottom Bracket

This bottom bracket is designed specifically for cranksets with a 29mm spindle diameter, such as those using the SRAM DUB standard, allowing them to fit into frames with a 41mm PressFit shell.

This unit is compatible with frames featuring a 41mm inner diameter shell, which is standard for BB86, BB89.5, and BB92 configurations. It is designed to work with shell widths ranging from 86.5mm to 132mm.

The dual-row bearing design increases the load capacity compared to standard single-row bearings. This helps the bottom bracket handle the higher stresses of modern riding while extending the overall lifespan of the component.

Yes, the bearings feature 440c stainless steel races. This material choice provides significantly better corrosion resistance than standard steel, making it a reliable choice for riders who frequently encounter wet or muddy conditions.

No, the kit includes a complete set of spacers and dust seals. These are included to ensure you can achieve a precise, secure fit across the supported range of shell widths without needing additional parts.
