Featuring trickle down technology from the range topping Dura-Ace, the Ultegra R8025 STI shifters & Hydraulic Disc Calipers provide superbly crisp, precise and ultra-smooth shifting and powerful, consistent braking performance.Suitable for 2x11 Shimano drivetrainsPowerful hydraulic disc calipers provide excellent braking performance (Rotors & mounts sold separately)New chamferred hood tops for improved gripReliable performance in all conditionsShorter reach levers for riders with smaller handsWith the addition of powerful hydraulic disc brakes to the Ultegra range, the flat mount calipers house dual pistons that provide excellent stopping power in all conditions. Designed for 11-speed, double chainring systems, these shifters boast vastly improved ergonomics for more intuitive use, and newly chamferred tops to assist with grip in wet conditions. The lever features 15mm of reach adjustment so no matter your physiological requirements you will be able to tailor them to suit. The OPTISLICK cable technology features an electronically coated outer layer that assists with shifting efficiency and helps to weatherproof the shifters against corrosion. They also benefit from easier access to the inner cables, making these shifters eminently serviceable and a solid option for a year-round winter bike. The new ergonomic design features a new front-lever curve profile, which provides even faster and more comfortable shifting and brake engagement; it ensures performance is always at 100% and that every gear click and brake-pull feels natural and efficient. With effortless shifting performance, powerful braking and supremely comfortable ergonomics these shifters are the perfect upgrade for any rider.

Despite its smaller, lighter design, the Dura-Ace FD-R9250 brings the fastest front shifting on the market. The fastest just got faster thanks to the Dura-Ace FD-R9250. Tipping the scales under 100 grams, the new design shifts 45% quicker than Shimano's FD-R9150, already the fastest on the market. And the frontal area of the FD-R9250 is also reduced to decrease aerodynamic drag. Shimano Di2 Electronic Drivetrain Performance Thanks to its lightning-fast, accurate, and reliable shifting performance, Di2 puts riders in complete control and ensures a seamless interface between the cyclist and bike like never before. Creating and continually improving the world's best shifting is a complicated undertaking requiring constant technological advancements.

Shimano's genuine application E-Tube Project for Mobile allows you to customize your bike, update firmware, and maintain it by connecting it wirelessly to your bike. You can also get more detailed bike maintenance by connecting to your bike by wire with E-Tube Project via the Windows V4 application. HYPERGLIDE+ Optimised HYPERGLIDE+ dedicated chain technology delivers greater chain retention, improved shifting efficiency, and smoother transmission over rough terrain. Improved chain retention encourages more aggressive all-terrain riding and relieves chain-issue anxiety. Smoother drivetrain transmission and enhanced shifting performance sharpens riders’ concentration and improves acceleration. Better chain engagement cuts abrasion, reduces maintenance, and lengthens the lifespan of the chain.
