The terms T700 and T800 refer to the type of carbon fiber used in carbon wheels and other carbon components. These designations originate from Toray Industries , one of the world's leading suppliers of carbon fibers. The numbers indicate the type of fiber and its properties.
Here is a brief explanation:
- T700 :
- This carbon fiber is widely used and is considered a standard material for many bicycle components.
- Properties: It offers a good balance between stiffness, strength, and cost. T700 is resistant to breakage and easy to process, making it a popular choice for frames and wheels.
- Stiffness/Strength: Solid and sufficient for most needs, especially for recreational athletes or amateurs.
Here's a picture of T700 carbon fiber. It shows the fine, dense fibers that make the material strong and flexible.
- T800 :
- This carbon fiber is a higher version and is often used in high-end components.
- Properties: It is stronger and stiffer than T700, meaning less material is needed to achieve the same strength. This results in lighter yet highly durable components.
- Stiffness/strength: Higher than T700, resulting in better performance, especially in terms of weight and responsiveness. T800 is often used in professional or very high-end bicycles and wheels.
Here's an image of T800 carbon fiber. It shows a finer and denser structure compared to T700, highlighting the advanced properties of this fiber.
Conclusion : T700 is more robust and cost-effective, while T800 provides a lighter and more powerful construction, but is more expensive.
Conclusion: Carbon wheels from all manufacturers (or rather brands), whether inexpensive or expensive, that are assembled with these materials are all of the same quality. There are no more or fewer breakages.
