Wheels Manufacturing Sealed Cartridge Bearing ID 18mm/OD 30mm/Width 7mm 2RS - Pair
Upgrade your ride with Wheels Manufacturing Precision Steel Cartridge Bearings, engineered for durability and performance. These premium-grade replacement bearings are ideal for cyclists performing high-quality bike hub repairs, whether on road bikes, gravel bikes, or mountain bikes.
Unlike standard aftermarket bearings which are often grade 300 and can be up to 0.3mm out of round, Wheels Manufacturing bearings are manufactured to a much tighter tolerance. These are the same high-precision bearings found in top-tier Shimano and Campagnolo hubs, ensuring smoother rotation, improved longevity, and reliable performance under load.
Each bearing features heat-treated steel races and is fully sealed to protect against dirt, moisture, and grit, making them perfect for year-round riding and demanding conditions.
