  • GXP is the key to unlocking the potential of your bike. GXP components are essential for getting the most out of your ride. Thanks to GXP, you can go faster and harder than ever before. So what are you waiting for? Get out there and ride!

What is BB30?

BB30 is a type of bottom bracket that is used on bicycles. It is distinguished from other types of bottom brackets by its larger diameter, which allows for a wider range of gears to be used. BB30 bottom brackets are also known for being very lightweight and durable. The BB30 system was first introduced in 2000 by the SRAM Corporation, and it has since become one of the most popular types of bottom brackets on the market. While BB30 bottom brackets are usually found on high-end road and mountain bikes, they can be used on any type of bicycle.

Difference between GXP and BB30

GXP and BB30 are two different types of bottom bracket shells. GXP uses a sealed cartridge bearing system that is pressed into place. The BB30 bottom bracket shell is an open design that allows bearings to be placed directly into the frame. GXP is typically found on lower-end bikes, while BB30 is typically found on higher-end bikes. GXP bottom brackets are easier to install and maintain, but they are also more susceptible to creaking and require more frequent replacement. BB30 bottom brackets are more difficult to install but offer a smoother ride and longer lasting performance.


Bottom brackets have been around for a long time and come in many different varieties. We’ve looked at two of the most popular types, GXP and BB30. Hopefully this article has helped you understand the difference between the two and decide which type is best for your bike. Thanks for reading!
