Shimano R7000 105
The redesigned internal transmission device makes the control rod thinner and more ergonomically shaoed, bringing rapid and intuitive shifting and reliable braking.

Carbon Fiber Fork
Reduce the weight of the front fork, reduce the resistance,and improve its lateral rigidity, giving it a unique windbreaking structure to achieve precise control of the bicycle.

Front Derailleur
The new chain link structure can be easily set and fine-tuned without special tools, which more naturally matches the force curve of the hand, and can be easily shifted.

Rear Derailleur
The thin design increases the shifting stability and reduces the collision vulnerability.

Lightweight Design
The hollow design is obviously helpful for improving the rigidity of cross-legged while reducing weight. The design of the integrated chainring is more controllable, and the riding is more powerful.

Floating Disc
The unique rivet link not only achieves a lightweight design, reduces heat transfer, and avoids brake deformation.
