The Enduro Bearings BSA - BB - 440C Stainless Steel Angular Contact Bottom Bracket offers a reliable and durable solution for cyclists seeking smooth performance in challenging environments. Designed to thread seamlessly into your BSA bottom bracket shell, this component ensures effortless installation and a secure fit for your crankset. Crafted with 440C stainless steel balls and races, it delivers superior corrosion resistance and longevity, making it ideal for riders exposed to wet conditions or frequent bike washes.
Equipped with LLB type seals and packed with Kluber CRC Marine Grease, this bottom bracket is engineered for enhanced water resistance and protection against the elements. While stainless steel offers slightly lower load capacity compared to traditional chromium steel, its resilience to moisture and sweat makes it a preferred choice for endurance and everyday cyclists alike. Backed by a two-year warranty and a three-year anti-corrosion guarantee, Enduro Bearings stands behind the quality and performance of this premium component.
This bottom bracket supports multiple axle sizes including 24mm, 29mm (DUB), and 30mm, accommodating a wide range of cranksets, especially 30mm spindle lengths of 104mm or longer. Whether upgrading your current setup or building a new bike, this component blends reliability with advanced materials to enhance your ride.
Can this bottom bracket be used in wet or muddy conditions?
Yes, the 440C stainless steel bearings combined with LLB seals and Kluber CRC Marine Grease make it highly resistant to corrosion and water ingress, making it suitable for wet or muddy riding.
Is this bottom bracket compatible with all crank spindle sizes?
It supports 24mm, 29mm (DUB), and 30mm spindle sizes, but for 30mm axles, the crank spindle length should be 104mm or longer for proper fitment.
