Lightweight Carbon Road Bike for Cyclists

With the 105 ST-R7120 Dual Control lever, road cyclists can enjoy confident handling. The mechanical 12-speed components of the 105 series offer a shifting system suitable for a wide range of road cycling needs. The ST-R7120 shift/brake levers not only provide the fast and intuitive shifting quality typical of the 105 series, but also excel in ergonomics, with improved grip and optimized comfort features.

The 105 FD-R7100 front derailleur is characterized by a light, harmonious, and natural shifting behavior, as well as simple and precise adjustability, making it an ideal companion for the 12-speed drivetrain.

The 105 RD-R7100 rear derailleur combines the harmonious, consistent, and responsive shifting behavior of the Shadow RD design with Direct Mount compatibility and a wider ratio range. The Top Normal rear derailleur enables energy-saving transmission with a ratio of less than 1:1, which is ideal for climbing and supports the rider when tackling steep inclines.

The hydraulic 105 BR-R7170 disc brakes allow athletes to push their limits even further. A 10% larger pad spacing compared to the previous model reduces the risk of unwanted brake friction and grinding brake discs, resulting in quieter deceleration. These calipers grip quickly and reliably, providing confident braking performance.

The CS-HG710 cassette, with a gear ratio range of 327%, is optimally equipped to handle diverse terrain requirements. Whether sprinting on the flat or tackling steep climbs, the 12-speed sprocket set, with a gradation of 11 to 36 teeth, has the right answer for every situation.

The FC-R7100-12 crankset offers road cyclists an extremely lightweight yet powerful solution, with durable arms that provide efficient power transmission. The thoughtfully designed chainrings are perfectly matched to the FD-R7150 front derailleur, resulting in fast and precise shifting behavior.

The road bike features a lightweight T800 carbon fiber frame, carbon front fork, carbon seat post tube, and carbon wheelset, weighing only 8.8 kg (19.4 lb). The hardness of the carbon fiber material is 5 times higher than that of an aluminum alloy bicycle frame, providing a lightweight and durable design suitable for racers.

The bike is equipped with the 105 R7120 2x12-speed groupset, including shifter levers, front derailleur, rear derailleur, crankset, and cassette. This setup enables effective, smooth, and durable shifting, making it an excellent choice for race cyclists.

The 105 R7120 hydraulic disc brake system, with R7120 levers and R7170 calipers, provides long-lasting and powerful braking performance, superior to conventional V-brake systems, ensuring stable and confident stops.

The entire road bike features a fully integrated internal cable design, which optimizes airflow and creates a clean, tidy, and beautiful appearance, reducing wind tunnel resistance and providing a smoother riding experience. The tapered head tube also enhances torsional rigidity for better handling.

The bike is equipped with 700x25C Continental tires on lightweight carbon wheelsets, suitable for various road conditions. The anti-skid design on both sides increases grip and confidence when turning at high speeds.

The carbon road bike is 90% pre-assembled before shipping, ensuring a hassle-free setup for both bike commuters and professional entry-level racers.
