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 are 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.
ITA bb’s, thanks to the popularity of Italian road bike design, still have a following. The drive-side cup needs to be properly secured, but once that’s done, the system is excellent. 24mm cranks work better when mated to our bearings.
To have your bike as efficient as possible, reduce mechanical drag. Bottom brackets have a measurable effect on speed. CS balls are 100% smoother and 15% harder than the ceramic competition. They run on smoother races, too. They reduce the drag of our Standard Bearing bb’s by 75% when compared to typical bottom brackets. The bearings last at least 3x longer than other bearings.
These bearings come packed with Round Grease. If you want less drag and are riding in cleaner environs, install the lowest drag Race Day Grease. If you’re riding in wet conditions, a more durable Long-Life Grease can be put in.
If you don't have any experience installing bottom brackets and bearings, we recommend that you have your local bike shop fit your new bearings.
We recommend that you follow our instructions on how to maintain your CeramicSpeed Bottom Brackets to achieve the lowest friction and the best longevity.
