Using Hollowtech I technology to optimised power transmission as well as faster and more precise shifting operations.

Front Derailleur

The front derailleur provides ultra-smooth shifting. It moves your chain up and down perfectly, with no extra effort. The result is precise and direct shifting with no delay.

Rear Derailleur

Thinner assembly structure provides a more streamlined and integrated assembly. The pulleys are kept at a consistent distance from the cassette for improved shift stability.
