Enduro 440C T47 Internal Stainless Steel Bottom Bracket 

Upgrade your ride with relentless all-weather performance using the Enduro 440C T47 Internal Stainless Steel Bottom Bracket. Manufactured at Enduro's production facility in California, USA, this system pairs angular contact 440C stainless steel balls and races with precision-machined aluminum cups that thread directly into your frame. Designed specifically for riders who brave wet weather, wash their bikes frequently, or struggle with sweat damage, stainless steel delivers unmatched corrosion resistance where standard bearings fail. Equipped with dual-lip LLB seals and heavy-duty CRC Marine Grease, this thread-in solution creates a waterproof shield to keep your drivetrain spinning smoothly and silently through the harshest conditions.

Precision Design and Weatherproof Assurance

Engineered specifically for frames with 86mm T47 internal threaded bottom bracket shells, this complete bottom bracket provides an ideal fit for high-performance setups requiring maximum weather protection. While 440C stainless steel offers around twenty percent less load capacity than traditional chromium steel, it completely eliminates the risk of rust and pitting caused by moisture ingress. The inclusion of specialized angular contact bearings ensures that both radial and lateral loads are evenly distributed across larger contact areas, reducing overall wear and play. Enduro stands so strongly behind this engineering that every unit comes backed by a comprehensive three-year anti-corrosion guarantee.
