Wheels Manufacturing Sealed Cartridge Bearings 6903 – Pair (17 x 30 x 7mm)
Upgrade your bike’s performance with the Wheels Manufacturing 6903 Sealed Cartridge Bearings, a premium-quality replacement bearing set designed for durability, precision, and long-lasting smoothness. Supplied as a pair, these bearings are the ideal solution for hubs, bottom brackets, and other high-performance cycling components.
Unlike most aftermarket bearings, which are typically grade 300 (up to 0.3mm out of round), Wheels Manufacturing bearings use a higher-grade steel equivalent to those found in high-end Shimano and Campagnolo hubs. Featuring heat-treated steel races and fully sealed construction, these cartridge bearings ensure maximum protection against dirt, water, and wear, giving your bike superior reliability and extended service life.
Engineered for precision, efficiency, and durability, the Wheels Manufacturing 6903 Sealed Cartridge Bearings deliver lasting performance and a smoother ride, making them the go-to choice for professional-quality bike repairs and upgrades.
