Shimano Ultegra Set Right 12 Deslocador

Shimano's ULTEGRA ST-R8170 brake levers bring enhanced modulation and control to every ride by employing Shimano's proven SERVO WAVE technology. The all-new Di2 platform, used on both DURA-ACE and ULTEGRA, untethers the shifters while delivering our fastest, most reliable wireless shifting. Your time on the bike is precious, let Shimano make it even better.

Technologies

Dual Control Lever

• Dual Control Lever have an optimized structure with features that include the lighter weight pivot section in the near side of the shifting unit and the integral shifting cable for lighter steering. Its many component parts are made so compact and precise to achieve unprecedented high-speed performance.

Reach Adjust

• Brake lever is equipped with a reach adjust mechanism. The distance from handlebar grip to lever can be adjusted to suit any hand size, type of riding and individual rider preferences.

Servo Wave Action

• When you pull a SERVOWAVE brake lever, initial pad travel is fast, so little lever movement is needed to bring the pads into contact with the rotor. The power multiplication factor then increases rapidly at the pad-to-rim contact so more of the lever stroke is used to apply greater braking power with improved control.

The ULTEGRA R8170 disc brake caliper brings a new level of control to the road cycling world with enhanced modulation and a quicker initial braking point. Despite its smaller construction, the system is quieter than ever and easier to maintain.

Technologies

One Way Bleeding

• ''ONE WAY BLEEDING'' was developed for quick and easy prevention of air in hydraulic system. We have streamlined the oil route throughout the system to prevent air bubbles from being captured in the system. One way oil routing plus a funnel tool with mineral oil provides an easy and clean bleeding system.

Ice Technologies

• The fade, which can occur to disc brake rotor and pad when braking on a long downhill ride for instance, has a negative impact on the braking performance. SHIMANO has adopted ICE TECHNOLOGIES disc brake rotor and ICE TECHNOLOGIES pad to realize the cooling technology for consistent performance. The clad disc brake rotor blade, which has a 3 layer-sandwich structure of stainless steel, aluminum and stainless steel, provides better radiation performance. Also, the radiation fin has been adopted for the pad. Moreover, the clad disc brake rotor blade and the radiator fin provide long pad life, less noise, less fade and lightweight.
