Wolf Tooth Bottom Bracket

Wolf Tooth T47 Inboard bottom brackets are engineered to be durable reliable lightweight and smooth. The weather sealing is best-in-class with o-ring seals on the spindle and inner shell a wiper connection seal between the bearing and end cap bearing race seals and a labyrinth end cap design. To prevent creaking spindle bushings separate the bearing inner race and crank spindle to eliminate metal-on-metal contact. The custom chrome bearings has been hardened for improved durability and reduced friction with ZNA corrosion-resistant coating while the ball diameter width and counts were custom selected by Wolf Tooth for top quality based on spindle diameter. Wolf Tooth bottom brackets are machined at Wolf Tooth in Minnesota USA.
