Bottom Bracket

Finding the right bottom bracket or wheel bearings for your bike can be very challenging with so many different standards on the market.

We can help simplify the process of identifying the correct parts for you. By knowing your bike model and build year, or identifying your current bottom bracket model (check for any markings) and the crankset type, we can provide you with the exact parts you need.

For example, knowing you’re riding a 2024 Colnago V3 with a Shimano Ultegra crankset, we can quickly identify the compatible bottom bracket and guide you to the correct part on this site.

With nearly every type of bottom bracket in stock, we’re ready to help. Just reach out via email (info@aitaceramic.com), and we’ll respond promptly.

We’ve also prepared a quick reference guide to help you get started, but feel free to contact us for personalised support.

 

Please refer to the compatibility matrix below and the links to find the right AITA ceramic bottom bracket. AITA Ceramic provides solutions for transferring between the different standards with no adapters or spacers.

Step 1: Select FRAME type - Pressfit or Thread; confirm the bottom bracket shell WIDTH and INNER DIAMETER (ID)

Step 2: Select CRANKSET type

Step 3: Click the matching ceramic bottom bracket and link to the relevant product page

Pulley Wheels

The three main rear derailleur systems commonly found on bicycles are Shimano, SRAM and Campagnolo. Each brand offers different drivetrain configurations, including 10, 11 and 12-speed systems, with different derailleur models designed to accommodate specific jockey wheel sizes, such as 11T, 12T, 13T and 15T.

If you know your rear derailleur brand, model and number of speeds, and can confirm the maximum jockey wheel size supported by your current cage, you can easily use the following list to identify the compatible AITA Ceramic jockey wheels for your setup.
