ITA30 Ceramic Bottom Bracket
AITA ITA30 ceramic bottom bracket converts Italian thread frames to fit 30mm spindle EVO386, Rotor 3D+, Rotor 3DF, THM and Zipp cranks. But BB30 standard cranksets won’t work with this system.
This is a very ideal conversion bottom bracket to run an EVO386 30mm cranks on an Italian thread (ITA) frame without spacers.
However, with the other cranks such as Rotor 3D+ there will be two spacers required but all come with the bottom bracket.
With the Grade 3 Si3N4 ceramic balls (8 times rounder and 4 times smoother than the steel's), spinning on the hardened ABEC 7 races, this ceramic bottom bracket only consumes 20% of the power compared with a steel bearing bottom bracket in average, plus the bearings will last 3-5 times longer.
For this particular oversized bearing and the aluminium house, an installation tool is provided for an easier installation.
