CeramicSpeed BB30 Bottom Bracket

The main advantage is a significant reduction in friction. CeramicSpeed's ceramic balls are 100% smoother and 15% harder than standard steel bearings, which translates to less drag and more efficient power transfer with every pedal stroke.

The Coated version features a specialized metallic layer applied to the hardened-steel races. This makes the races harder and smoother, resulting in even lower drag and increased durability, especially in harsh riding conditions.

Yes, these bearings are designed to be serviceable. They come pre-packed with All Round Grease, but you can swap it for TT and Track Grease if you prioritize low drag in clean conditions, or LongLife Grease if you frequently ride in wet or muddy environments.

Yes, the precision-machined aluminum housing is designed to provide a secure, stable fit within your frame's bottom bracket shell, which is highly effective at minimizing the movement that typically causes creaking.

Yes, this kit is specifically engineered for 24mm thru-axle spindles, making it a direct fit for most standard Shimano road cranksets.

Maintenance frequency depends on your riding conditions. While the seals are highly effective at keeping contaminants out, we recommend inspecting and potentially re-greasing your bearings at least once a season, or more frequently if you regularly ride in wet or gritty weather.
