The Wolf Tooth "MK0 BSA" MTB Bottom Bracket - Ceramic is the ceramic bottom bracket of the Wolf Tooth MK0 line: the cups and seals of the BSA bottom bracket with bearings running silicon nitride balls on hardened chrome steel races with ACOSUR ZNA corrosion protection. Where other ceramic bottom brackets spin freely and wear quickly, Wolf Tooth keeps the sealing of its steel bearing, uses POM spindle bushings with even lower seal drag, and spends extra time in the CNC lathe, which saves weight and leaves the visible machine paths of the MK0 parts. The adjustable sleeve fits 68 and 73 mm, sleeves for 83 and 100 mm are available as add-ons, spindle and shell spacers are included. Shadow Gray, 76 g (24 mm), 82 g (29 mm) or 77 g (30 mm) according to the manufacturer, machined and assembled in Minnesota.
