"What Our Gearhead® Experts Are Saying: ""This upgrade took my wheels to another level. Smoother rolling, noticeably better power transfer, and you can feel the reduced drag on long rides. Installation was a breeze, and knowing they’re hand-built just adds confidence to the quality."" We demand every watt counts—on the flats, in the break, or grinding up alpine grades. That’s why we trust the Zipp Ceramic Bearing Upgrade Kit, featuring CeramicSpeed’s industry-leading grade 3 Silicon Nitride balls. Hand-built in Denmark and matched to polished steel raceways with micrometer precision, these bearings offer a near-frictionless spin that maximizes speed and durability. Whether we’re building out a race-ready setup or fine-tuning our daily driver, the non-contact sealed design keeps contaminants out while CeramicSpeed’s Blue Grease keeps performance smooth and consistent. The payoff? Reduced rolling resistance, improved power transfer, and longer service life—across every road discipline we ride."
