CeramicSpeed T4530 Bottom Bracket

Colnago developed the ThreadFit82.5 (also known as ThreadFit) to make their oversized bottom brackets more durable. The T4530 bottom bracket is screwed into these 45 mm large, 82.5 mm wide shells and allows the installation of cranks with a 30 mm axle diameter on your Colnago. The cups come with pressed-in CeramicSpeed bearings. There are two bearing options available: The standard bearing features CeramicSpeed balls and hardened steel rings. The coated bearing runs with the same balls on a 3-micrometer thick coating over the hardened steel rings, making them faster and more durable.
