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 cranks, such as those from Shimano, FSA, and others into an ITA shell.
CeramicSpeed bearings are pressed into threaded cups, then those cups are threaded into the frame. You choose whether you want yours equipped with 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 BBs, 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 make your bike as efficient as possible, you must reduce mechanical drag. Bottom brackets have a measurable effect on speed. CeramicSpeed balls are 100% smoother and 15% harder than the ceramic competition. They run on smoother races, too. That means our Standard Bearing BBs have 75% less drag compared to typical bottom brackets. And, the bearings last at least 3x longer than other bearings.
These bearings come packed with All Round Grease. If you want less drag and are riding in cleaner environs, install lowest drag TT and Track Grease. If you're riding in wet conditions, more durable LongLife Grease can be put in.
