Wolf Tooth Tackles Creaks & Grit with New USA-Made Bottom Brackets
Wolf Tooth launches new durable, anti-creak bottom brackets with advanced sealing, custom bearings, and USA manufacturing. Available in BSA & T47.
Wolf Tooth, the Minnesota-based manufacturer known for its precision-machined cycling components, has just launched a new line of bottom brackets, meticulously engineered to deliver durability, smooth performance, and an end to those dreaded creaks. True to Wolf Tooth's reputation, these bottom brackets are not only built to last but are also rebuildable, underscoring their "Right to Repair" philosophy.
At the core of these new bottom brackets is a focus on robust materials and exceptional sealing. The custom-designed bearings feature balls and races made from hardened chrome bearing steel, which Wolf Tooth notes has a higher surface hardness than stainless steel for improved durability and reduced rolling resistance. An ACOSUR ZNA coating is applied to the races, providing corrosion resistance reportedly equal to or better than stainless steel, proven through a 500-hour saltwater test. Wolf Tooth confidently describes the sealing as "best-in-class," incorporating a system of five seals and o-rings across the spindle, bearing gutters, inner and outer bearing races, shells, and labyrinth-style end caps. This extensive sealing is designed to balance low drag with superior protection against all weather conditions.
One of the most welcome features for many riders will be the dedicated anti-creak design. Wolf Tooth employs custom spindle bushings that separate the bearing inner race from the crank spindle. This eliminates direct metal-on-metal contact, which is identified as a leading cause of bottom bracket creaks, while also enhancing bearing longevity by interfacing with the bearing gutter seal for maximum weatherproofing.
Compatibility is extensive, with options for BSA and T47 internal standards catering to 24mm, 29mm (DUB), and 30mm spindles. The BSA models feature adjustable-width sleeves to fit 68mm and 73mm shells, with additional sleeve options for 83mm and 100mm widths. T47 Internal models are designed for shells ranging from 85.5mm to 92mm. Wolf Tooth also highlights that these bottom brackets are lighter than most comparable options on the market.
Installation can be accomplished with standard tools, though Wolf Tooth also offers its own bottom bracket tools for convenience. Staying true to their colorful component ecosystem, the new bottom brackets are available in Black, Raw Silver, Orange, and Ultraviolet Purple, allowing riders to coordinate with other items from the Wolf Tooth Color Shop.
These new Wolf Tooth bottom brackets are machined in Minnesota, USA, and are available now. BSA sizes are priced at $129.95, while T47 internal sizes retail for $139.95. You can find them on WolfToothComponents.com and at bike shops that stock Wolf Tooth products.
