$66.38
Description
For cyclists demanding speed and reliability, the Zipp 77/177 Hub CeramicSpeed Bearings pair revolutionizes wheel performance. Built for Zipp’s proprietary 61803 Modified hub design, these bearings integrate CeramicSpeed’s diamond-like carbon-coated balls and precision-sealed races to slash friction by up to 50%, translating to faster acceleration and smoother rides over mixed terrain. Engineered to withstand extreme loads (tested at 12k RPM), they resist corrosion from moisture, mud, or road salt—common adversaries of standard steel bearings that degrade performance and lifespan.
The pre-lubricated system uses World Record™ grease for instant functionality out of the box, while their hardened stainless-steel races ensure durability without added weight. Compared to conventional options:
– 50% lower rolling resistance (vs standard steel)
– 10x longer service interval (lab-tested at 10k+ miles per regrease)
– 100% compatible with Zipp 808 NSW/404 Firecrest/303 SLX hubs
Perfect for competitive road racers or gravel adventurers seeking consistent speed without frequent maintenance pauses. The tool-free installation fits seamlessly into existing hubs—no machining required.
Optimize your Zipp-equipped wheels with CeramicSpeed’s proven low-friction technology: “Upgrade hub efficiency without sacrificing ride comfort” becomes your new performance standard.
