Wolf Tooth Bottom Bracket Sleeves

Wolf Tooth Bottom Bracket Sleeves are precision-machined internal sleeves designed to optimize bottom bracket performance across a range of shell widths and spindle standards. Built to integrate seamlessly with Wolf Tooth bottom brackets, these sleeves improve internal alignment, sealing, and structural stability—especially in wider BSA and T47 frames.

Manufactured from durable machined acetal, these sleeves are lightweight, corrosion-resistant, and dimensionally stable. They help reduce contamination between the cups while supporting proper spacing and internal protection in demanding riding conditions. Whether you’re building a gravel bike, trail machine, or fat bike, the correct bottom bracket sleeve ensures your drivetrain operates smoothly and quietly.
