Campagnolo’s finest ceramic bearings are fitted to only the very best hubs and cranksets, and are a significant upgrade from all other bearings. Their premium quality ceramic balls are incredibly round and hard, and rotate within wear-resistant stainless steel races, which are engineered to micron-precise tolerances, maximising efficiency and durability. They won’t deform or corrode, perform consistently over time, and only need periodic cleaning then lubricating with light synthetic oil.
CULT bearings have a friction coefficient 40% lower than standard sealed bearings, and in tests, can spin for 5 ½ times longer.
