Uberbike DUB Threaded (BSA) Compatible Ceramic Hybrid Replacement Sealed Bottom Bracket Bearings

Using ceramic hybrid bearings, they provide several key advantages over traditional steel bearings - the perfectly spherical ceramic balls significantly reduce rolling resistance, increase service life, and improve corrosion resistance, while being 40% lighter than steel. This results in smoother pedalling efficiency and enhanced longevity, making them ideal for both mountain and road bikes. Dual rubber seals help keep dirt out and lubrication in, ensuring consistent performance and long-term reliability in all conditions.
