The Shimano Ultegra 105 R8000 2 piston hydraulic rear disc brake for small hands is a kit that consists of the brake lever and the brake caliper plus the brake line. As for the brake lever, it gives the rider more control in all conditions thanks to Shimano's class-leading hydraulic disc brakes. A lighter front shifting action and their ergonomic shape make them even more attractive. On the other hand, the brake caliper, with a low-profile flat-bearing design, disc brakes provide greater control in all conditions without disrupting the aerodynamic lines of road bikes.

Characteristics of the handle:
- Use: Road
- Recommended brake calliper: BR-R8070

- Even lighter front derailleur when paired with a redesigned FD-R8000
- Clamp inner diameter: 23.8-24.2 mm
- Shimano mineral fluid
- Average weight: 554 g
- 2x11 speeds

Characteristics of the clamp:
- Use: Road
- Brake type: hydraulic disc brake (rear)

Technology:
- One Way Bleeding: has been developed for quick and easy prevention of air in our hydraulic system. They have streamlined the oil path in the system to avoid air bubbles in the system. The passing of oil in one direction plus a mineral oil funnel tool provides an easy and clean purge system.

- Ice-Technologies: Overheating, which can occur in the disc and pad when braking on long descents, has a negative impact on braking performance. Shimano has adopted Ice-Technologies disc and pad cooling technology for consistent performance. The coated disc blade, with a 3-layer sandwich structure of stainless steel, aluminium and stainless steel, provides better radiation performance. A radiation fin has also been adopted for the tablet. In addition, the coated disc blade and radiator fin ensure longer pad life, less noise, less overheating and light weight.

-DUAL CONTROL LEVER: It incorporates the brake and shift functions into the system and is easy to use. Ergonomic innovation is probably more important for the higher standard of performance than the added transmission. The new internal shift elements take advantage of the robustness of its MTB technology and are so smooth that you can shift effortlessly with just one finger both in front and behind. In fact, the rear derailleur is the ultimate expression of Shimano Total Integration, and you just have to experience it to understand it.

- Reach Adjust: The brake lever is equipped with a range adjustment mechanism. The distance between the handlebar grip and the lever can be adjusted to suit any size of hand or cycling style, as well as the individual preferences of the rider.

- Servo Wave Action: When a Servo Wave brake lever is pulled, the initial pad travel is fast, so only a slight movement of the lever is needed to bring the pads into contact with the brake disc. The power multiplier factor then increases rapidly at the 'pad/disc' contact point, so the lever travel is used to apply more braking power with greater control.

- SP41: The entire length of the outer case is pre-lubricated with a special silicone grease for quick and precise change. OT-SP41 greatly reduces inner cable friction to provide fast drive response and easy/effortless changeover. In addition, power loss due to gear shift delay and shift fatigue is also reduced, especially in hilly terrain and over long distances.
