BlackBearing B5 Bearing 15x28x7mm
The BlackBearing B5 is a high-quality precision bearing upgrade designed to perform reliably in the most demanding riding conditions. Built to ABEC 5 tolerance standards, the B5 offers a meaningful step up in precision and consistency over standard OEM bearings – a worthwhile upgrade for riders who cover serious kilometres or ride regularly in wet and muddy conditions across Victoria and beyond.
Chrome steel SAE52100 balls and rings are paired with an optimised internal design that improves load distribution and reduces friction for smoother, longer-lasting rotation. The chrome steel cage maintains consistent ball spacing under load, while reinforced 2RS dual-contact seals provide enhanced resistance to water and dust ingress – critical for bearings exposed to the wet trails and variable weather that Australian riding regularly delivers. High-quality grease throughout completes a bearing built to last well beyond the standard replacement interval.
At 15x28x7mm, this bearing fits a wide range of cycling applications including bottom brackets, hubs, headsets, and suspension pivots. Check your component specifications to confirm fitment before ordering.
