Italian-threaded bottom bracket shells are typically found on Italian-brand road bikes. The shell measures 70mm wide and has a 35mm inner diameter.
This kit has all the pieces necessary to install 24mm diameter spindle cranks into an ITA shell. Those cranks come from Shimano, FSA, and others.
CeramicSpeed bearings pressed into threaded cups, then threaded into the frame. Those bearings comprise either Standard or Coated Bearings. Super round, super smooth CeramicSpeed balls rotate in hardened-steel races in both. The Coated version has a metallic coating laid onto the races, making them even harder and smoother, resulting in longer life and lower drag.
In The Box:
• 2 threaded cups with bearings.
• 2 dust covers with built-in spacers.
• Spacer tube.
• 10mm syringe of All Round grease.
• Sticker sheet.
About CeramicSpeed coatings:
CeramicSpeed’s coated products offer the ultimate gains in performance and longevity. Our proprietary coating features several attributes that improve the longevity of CeramicSpeed Bearings. The increased hardness of the races, combined with the smoothness of theCeramicSpeed Balls results in virtually no wear on the bearing.
The coating is a metallic layer, which is 75% harder than the hardened steel races. The coating is applied in a very thin and even layer of 3 microns (0,003 mm) on the entire surface of the bearing race. Both the inside and the outside are treated to achieve optimal results.
