Road riding has never been this much fun. That's because the redesigned Ultegra ST-R8170 Dual Control Levers have all-new ergonomics, even more precise brake modulation, and wireless electronic shifting. This trifecta lets you focus on the next sprint, the next descent, or the next joke from your riding partner. Shimano's new 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 the world's fastest, most reliable wireless shifting. Your time on the bike is precious, let Shimano make it even better. Servo Wave Precise Braking Control When you pull a Servo Wave 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. Shimano DCL Dual Control Lever DCL stands for Dual Control Lever. It has brake and shifting functions in the system and enables easy operation. Ergonomic innovation is as critical to higher standard performance as the added gearing. The shift internals borrows the robustness from Shimano's MTB technology and is so smooth and effortless that one finger shifts front and rear are possible. Indeed, shifting is the ultimate act of Shimano Total Integration and simply has to be experienced to be understood. Please Note: this model is for the Shimano Ultegra R8170 Di2 12 Speed Disc Shifter only - the hydraulic brake caliper is sold separately.
The Shimano Ultegra R8100 series caliper brakes offer a clear contact feeling while balancing rigidity, weight, and stopping power. With increased clearance for 28mm tyres, the sleek design is still fetching. Powerful and Responsive Shimano SLR-EV Braking Efficiency SLR-EV is Shimano's SLR braking technology with a dual symmetric pivot brake caliper. The short-arm brake design employs two bearings and a roller to realize greater efficiency in the pivot area and deliver superior modulation and power for braking. Together with the BC-9000 brake cable, the latest calipers deliver 36% more braking power than Shimano's previous brake model.
Offering all the precision and functionality of the 12-Speed Shimano Dura-Ace power meter, the Ultegra FC-R8100-P power meter comes in a more affordable package. Scientific training requires accurate measurement and user-friendliness, and the new Ultegra R8100 power meter has both. Its dual-sided measurement is accurate within 1.5% and zero offset calibration is a quick and easy process. Perhaps most importantly, its long battery life, easy recharge, and ANT+ and Bluetooth®LE connectivity make using and recording your workouts easier than ever. Bluetooth LE and ANT+ Connectivity The Ultegra R8100 Power Meter brings everything a data-driven cyclist could want. Its integrated, waterproof design brings all-weather reliability while delivering accurate information including left/right balance. A rechargeable Li-ion battery is user-friendly and Bluetooth LE and ANT+ connectivity ensure easy setup. Hollowglide Chainring Technology Hollow technology on the outer chainring. The Hollowglide construction ensures high rigidity while its hollow structure cuts down on weight yet maintains strength. This provides better power transfer and quicker and more precise front shifting performance. Hollowtech II Forged Crank Arms A lightweight crankset not only reduces the bike’s weight but decreases rotating mass to aid in acceleration. The challenge is to reduce the weight of the crank without reducing its strength and rigidity. Shimano's advanced forging technology has solved the problem through the HOLLOWTECH crank. Just like high-quality frame tubing, a hollow crank arm can provide amazing strength and rigidity at very lightweight. The Best Balance of Stiffness, Strength and Weight The concept of Hollowtech II technology is focused on producing a superior crankset that will maximize a rider’s power transfer. The rigidity of the crankset ensures pedalling efficiency while its low weight, a key element of the crankset, aids in cycling longer distances over which the rider needs to pedal more. Naturally, Shimano strove for the optimum balance between the conflicting needs of stiffness while producing a lightweight crank. The addition of Hollowtech II technology integrates the bottom bracket axle with the right crankarm for more stiffness and weight savings to achieve a high-dimensional balance. Its outboard bottom bracket bearing system provides better weight distribution and more pedalling stability, allowing for more efficient power transfer.
Now simplified with a single derailleur cage length, the new 12-Speed Shimano Ultegra R8150 rear derailleur packs the fastest, most precise shifting on the market into a more affordable option.
