Wolf Tooth Bottom Bracket Sleeves

Wolf Tooth Bottom Bracket Sleeves Info

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.
