The CeramicSpeed ITA30 Bottom Bracket is designed to deliver the lowest friction and the highest power transfer for riders using 30 mm spindle cranks. Built for Italian-threaded road frames, it brings world-class performance to a shell that is only 35 mm in diameter and 70 mm wide.

Perfect Fit for 30mm Spindle Cranks: This innovative design enables smooth compatibility between ITA frames and modern 30 mm spindle cranksets such as Rotor. By bridging the narrow shell width with oversized crank spindles, the ITA30 ensures stiffness, responsiveness and long-lasting efficiency on the road.

Hand-Built Bearing Precision: Each kit comes with CeramicSpeed bearings pre-installed in threaded cups for secure and straightforward installation. Riders can choose between Standard and Coated Bearings, both featuring ultra-round CeramicSpeed balls paired with hardened-steel races for unmatched rotational smoothness.

Coated Bearings for Extended Lifespan: The Coated version enhances durability with a 3-micron metallic layer applied to the races, making them harder, smoother and more resistant to contamination. This results in reduced drag, longer service intervals and superior longevity even under demanding riding conditions.

With industry-leading ceramic technology and exceptional resistance to wear, the ITA30 Bottom Bracket delivers long-term performance you can trust on every ride.
