Shift/Brake Lever

The Sora ST-R3000 shift/brake lever has braking and shifting functions and allows easy operation.

Upgraded Crankset

8 reinforced points are distributed on the bicycle crankset, which not only makes crankset more durable, but also enhances the riding efficiency.

Front Derailleur

The SORA R3000 front derailleur provides lighter 2x9 speed shifting thanks to its long arm design.

Rear Derailleur

SORA Medium Cage Rear Derailleur 9-speed. Using shadow design, thinner assembly structure provides a more streamlined integrated fit. The pulley maintains consistent distance to the cassette for increased shift stability.

Hydraulic Disc Brakes

Easy maintenance, stable performance and sensitive braking.

Floating Disc

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


Starting from the needs of riders, we are committed to providing riders with "professional carbon bikes with cost performance".
