Wolf Tooth Bottom Bracket

This bottom bracket is designed for frames with a standard English (BSA) threaded shell, specifically those with a shell width of 68mm or 73mm. Please verify your frame's bottom bracket standard before purchasing, as it will not fit press-fit or other non-threaded systems.

This unit is precision-engineered specifically for cranksets with a 29mm spindle diameter. It is commonly used for SRAM DUB cranksets, but you should always confirm your specific crankset's spindle size to ensure a proper fit.

Yes, the bottom bracket includes the necessary spacers to accommodate both 68mm and 73mm shell widths. This ensures you can achieve the correct chainline and fit for your specific frame setup.

Wolf Tooth components are machined to tighter tolerances than many stock options, which typically results in smoother rotation and increased durability. The precision engineering helps minimize play and ensures more efficient power transfer through your drivetrain.

Like any high-performance component, it benefits from periodic inspection and cleaning. While it is built for durability, keeping the area free of grit and ensuring the bearings are properly greased during installation will help maintain its smooth operation over time.
