The Blackbearing BSA 68/73-Dub B5 Bottom Bracket is engineered to enhance your bike’s efficiency with precision and durability. Designed for frames with a 68/73 mm width, this screw-on bottom bracket features machined aluminum cups that fit securely to optimize housing alignment.
Enhanced Alignment for Maximum Fluidity: With two aluminum cups that screw into each other, this bottom bracket provides improved alignment, ensuring smooth operation and minimizing resistance. This precise fit enhances fluidity, leading to better performance on every ride.
Interchangeable Bearings for Eco-Friendly Maintenance: The Blackbearing BSA 68/73-Dub B5 offers a sustainable solution with its interchangeable bearings. Instead of replacing the entire bottom bracket, you can simply swap out the bearings, saving time and resources.
Extended Bearing Life and Frame Protection: The optimal alignment reduces stress on the frame, lowering the risk of cracking and extending the life of your bearings. This thoughtful design is perfect for riders who prioritize reliability and longevity in their cycling components.
Changing bearings doesn’t require extracting the entire bottom bracket body, minimizing the risk of frame damage and simplifying maintenance.
