The biking sector is one sector that fascinates almost everyone. Young boys are the most interested in bikes and opt for the latest technologies for biking. Because of the increasing demand for the biking sector, this sector keeps coming up with the latest technologies daily.
Among the various technologies used in the biking industry, GXP and BB30 are two very common ones. Both of these are referred to as the design systems of a bike. They include the bike frame, the crankset, and the button bracket shell of a bike.
The manufacturers of bikes use GXP and BB30 for the production of bikes. These are also used regularly by people who are passionate about their bikes and want to build bikes as per their designs. These are thus commonly used by people all around.
Though both these technologies have great similarities, they are quite different from each other. They are unique in their ways and cannot be used interchangeably.
- GXP and BB30 are bottom bracket systems used in bicycle frames.
- GXP has a spindle with a stepped diameter, while BB30 has a straight, 30mm diameter spindle.
- BB30 is lighter and stiffer than GXP, but GXP is more compatible with various cranksets and frames.
GXP vs. BB30
The difference between GXP and BB30 is that the full form of GXP is Giga X Pipe. On the other hand, the full form of BB30 is Bottom Bracket. The GXP measures 5.1 by 3.4 by 2.2 inches and weighs 145g. On the other hand, the BB30 measures 4.5 by 2.3 by 2.3 inches, and its weight is 153g.

What is GXP?
The GXP is one of the most commonly used technologies used in biking. It stands for Giga X Pipe. The design system consists of a bike frame, bottom bracket shell, and crankset. The bottom bracket component is the most important among them.
The GXP has ceramic bearing technology. This enables a smooth-riding of the bike. It also assures moisture and dirt resistance for the bike. Moreover, the bottom bracket is very light, making the ride efficient. The total weight of the GXP is 145g.
The GXP is available in a red-black color theme. This color enables a glow to the bike. There is little chance of rust on the bike because of the GXP. If the GXP is maintained and kept carefully, it uses 78% less energy.
The GXP has CNC-machined aluminum. This helps it to be a lightweight unit. This also adds to the strength and durability of the bike. There is no need to side-load the bearing if any adjustments are to be made.
Thus the GXP technology has made biking easier and more efficient. The only drawback of GXP is that an adapter is needed to install a 24mm crank into a GXP. This might add to the cost as an adapter must be purchased.
What is BB30?
BB30 stands for Bottom Bracket. It is another commonly used technology for bikes. It helps enhance the performance of bikes. It also makes the bike last longer. It has aluminum cups which add to the durability of the bike.
The size of the BB30 is smaller. The measurements are 4.5 by 2.3 by 2.3 inches. The weight of the BB30 is 153g. They have silicone seals on their bearings. This keeps them safe and prevents any contamination. Because the bearings are perfectly sealed, it is easier to maintain the BB30.
The BB30 is designed to install the 24mm cranks into the frames easily. No kind of adapter is required to do so. It is easier to replace the bearings of the BB30. This makes operating it smoother.
Main Differences Between GXP and BB30
- The full form of GXP is Giga X Pipe, whereas, on the other hand, the full form of BB30 is Bottom Bracket.
- The theme color of the GXP is red-black, while the other hand, the theme color of the BB30 is solid black.
- The GXP weighs 145g while on the other hand, the BB30 weighs 153g.
- The bearing of a GXP has a ceramic seal, while on the other hand, the bearing of a BB30 has a silicone seal.
- The measurements of a GXP are 5.1 by 3.4 by 2.2 inches, whereas, on the other hand, the measurements of BB30 are 4.5 by 2.3 by 2.3 inches.
- The GXP spindle is smaller with a 24mm spindle, whereas the BB30 spindle is bigger with a 30mm spindle.
- An adapter is needed to install a 24mm crank into a GXP; however, an adapter is not necessary to install a 24mm crank into a BB30.
