Wolf Tooth MK0 Ceramic Bottom Bracket – BSA, 68/73mm, 24mm Spindle

Description

Elevate your cycling performance with the Wolf Tooth MK0 Bottom Bracket – the ultimate choice for serious mountain bikers and road cyclists seeking durability, precision, and unmatched efficiency. Designed for 68/73mm BSA shell widths and compatible with 24mm spindle cranksets, this premium bottom bracket combines innovative engineering with high-quality materials to deliver superior performance across all terrains.

Materials & Durability: Crafted from lightweight 6061-T6 aluminum cups and housed within a hardened AISI 52100 chrome bearing race, the MK0 Bottom Bracket boasts exceptional strength and corrosion resistance. The silicon nitride ceramic bearings reduce friction, provide long-lasting smoothness, and resist contamination for reliable operation in mud, water, and debris.

Performance & Engineering: Featuring custom-designed, low-drag seals made of urethane and NBR, this bottom bracket ensures consistent, frictionless rotation. The inclusion of custom polymer spindle bushings eliminates metal-on-metal contact, significantly reducing creaking and enhancing bearing longevity. Machined with precision, the MK0 is intentionally lightweight without sacrificing strength, enabling faster acceleration and efficient power transfer.

Components & Technology: Thanks to its adjustable-width internal sleeve, the MK0 Bottom Bracket fits 68 to 73mm BSA shells securely, with optional spacers available for wider shells up to 100mm. The ceramic bearings with sealed race technology provide best-in-class weatherproofing, protecting against water, mud, and dirt-ideal for aggressive trail riding or endurance racing. Installation and removal are straightforward using standard 44-16 or 46-12 spline tools.

Style & Use Case: Finished in a sleek Shadow Gray, this bottom bracket complements any bike aesthetic. Whether you’re mountain biking, gravel grinding, or road riding, the MK0 enhances drivetrain efficiency and ensures consistent performance in challenging conditions. Its aggressive machining reduces weight, while innovative features like the MK0 ceramic bearings set it apart from conventional bottom brackets.
