MK0 BSA Ceramic Bottom Bracket
Wolf Tooth Bottom Brackets set the bar for performance, weight, durability, and performance. The new MK0 Bottom Brackets group those best-in-class specs with a ceramic bearing. The sealing is especially important here. Where many ceramic bottom brackets are known for spinning without friction, they are not known for being durable. The MK0 Bottom Bracket eliminates that issue, with best-in-class sealing for never-ending performance. Like other MK0 items, these bottom brackets spent extra time in the CNC lathe to reduce weight with new, consistent aesthetics. Form has met function. This is the outcome.
- Premium ceramic bearings with low dragĀ seals are built to our exactingĀ specifications
- Adjustable-width sleeve fits 68mm - 73mmĀ BSA bottom bracket shells
- Best-in-class weather sealing protectsĀ bearings from water, mud, and debris
- Custom polymer spindle bushingsĀ eliminate creaking and the unique MKĆĀ version is modified for even lower seal drag
- Compatible with 24, 29 DUB, and 30mmĀ spindle cranksets
- Installation and removal with standardĀ 44-16 (24mm) and 46-12 (29mm DUB,Ā 30mm) spline tools
