Wolf Tooth Unveils Lifetime Warranty Bottom Brackets: Sealed, Strong, and Made in USA
Discover the new Wolf Tooth Bottom Bracket. USA-made, durable, smooth & sealed. Features custom bearings, anti-creak tech, color options & lifetime warranty.
Minnesota's Wolf Tooth Components (WTC), renowned for its high-quality CNC-machined bike parts and accessories, has made a significant move into a core drivetrain component category with the launch of its new Wolf Tooth Bottom Bracket. Signaled as the first of four major product announcements planned for the year, this launch marks a substantial expansion for the company known for its attention to detail and engineering prowess.
Engineered for Performance and Longevity
Wolf Tooth Components states its new bottom brackets are engineered with key rider demands in mind: durability, reliability, light weight, and smooth operation. True to the brand's roots, these bottom brackets are machined directly in their Minnesota, USA facility.
WTC is placing particular emphasis on the sealing system, claiming it provides "best-in-class" weather protection. This comprehensive sealing involves seals integrated into the spindle interface, bearing gutters, inner and outer bearing races, the external shells, and the end caps, designed to guard the crucial bearing internals against water, dirt, and trail debris.
Addressing Common Issues: Creaking and Compatibility
A notable feature is the inclusion of custom polymer spindle bushings. These bushings sit between the crankset spindle and the bearing's inner race. According to WTC, this design eliminates direct metal-on-metal contact, effectively preventing the creaking noises that often plague bottom bracket areas and potentially extending the lifespan of the crankset spindle.
Compatibility is addressed with offerings in multiple BSA (threaded) and T47 Internal configurations, designed to work with the most common mountain and road crankset spindle diameters: 24mm (Shimano Hollowtech II), 29mm (SRAM DUB), and 30mm. Furthermore, the shells feature an adjustable width design; BSA models can accommodate both 68mm and 73mm bottom bracket shell widths, while the T47 internal models are designed for 85.5mm and 92mm wide shells.
Custom Bearings and Rider Convenience
The heart of the bottom bracket lies in its bearings. Wolf Tooth utilizes custom bearings made from AISI 52100 chrome steel, which is hardened to Rc 61-66 for improved durability and reduced friction. These bearings feature a ZNA corrosion-resistant coating. WTC notes that the specific ball bearing diameter, width, and count were carefully selected by their engineering team based on the spindle diameter to ensure high quality and performance.
Practicality extends to installation and service, which utilize standard spline bottom bracket tools. Aesthetically, the bottom brackets are available in several of Wolf Tooth's signature anodized colors – black, raw silver, orange, and ultraviolet purple – allowing riders to coordinate with other WTC components on their bikes.
Warranty, Repair, and Made in the USA
Standing behind their product, Wolf Tooth Components offers a lifetime warranty on their new bottom brackets. They also support longevity and serviceability through their "Wolf Tooth Right to Repair" program, ensuring replacement parts and service guides are available to consumers and shops. The "Made in USA" manufacturing is a key aspect highlighted for this product line.
For riders seeking a premium bottom bracket upgrade focused on durability, sealing, smooth performance, and quiet operation, backed by a lifetime warranty and domestic manufacturing, the new Wolf Tooth offering presents a compelling option.
