CeramicSpeed BB Alpha Gravel Italian Threaded

CeramicSpeed BB Alpha Gravel Italian Threaded is a gravel bottom bracket for frames with an Italian (ITA) threaded shell. CeramicSpeed builds the BB Alpha around hardened stainless-steel races and grade-3 Silicon Nitride ceramic balls, the same ceramic bearing approach the Danish company is known for, aimed at keeping friction low.

Moisture is the main enemy of any bottom bracket, and gravel riding gives it plenty of chances. CeramicSpeed gives the BB Alpha custom-engineered seals and precision dust covers, which it says provide up to 500% better moisture protection. A simplified spacer tube design makes installation quicker, and the cups are lighter, giving a claimed 10% weight reduction over previous generations.

The Alpha comes in versions for 30mm spindle, SRAM DUB and Shimano cranks, so pick the one that matches your crankset. CeramicSpeed backs every BB Alpha with a lifetime warranty and describes it as a bottom bracket built to outlast your frame. If you ride a gravel bike with an Italian-threaded shell and want a long-lived bearing set, this is the CeramicSpeed option.
