CeramicSpeed ITA Bottom Bracket for Shimano Road – Italian Precision Meets World-Class Efficiency
The CeramicSpeed ITA Bottom Bracket is designed for riders who demand both tradition and performance. Italian-threaded bottom bracket shells are a hallmark of premium Italian road bike design — measuring 70mm wide with a 35mm internal diameter — and this kit allows the installation of Shimano, FSA, and other 24mm spindle cranks into these classic frames.
Each kit includes two threaded aluminum cups pre-installed with CeramicSpeed Bearings, ensuring an ultra-smooth and efficient power transfer. These hand-built bearings feature perfectly round CeramicSpeed Balls rotating in hardened-steel races. The result is a bottom bracket system that dramatically reduces friction and improves durability for consistent, race-winning performance.
For those seeking even greater efficiency, the Coated version enhances the standard bearings with a thin, metallic surface layer that increases hardness, reduces drag, and provides superior protection against corrosion — delivering extended longevity and smoother pedaling under all conditions.
