Shimano Ultegra R8150 12 Speed Di2 Groupset

It's time — to find out what really matters.
The freedom of the open road, crisp mornings and fiery sunsets. Laughter filling the air and then trailing off.
Nature, unfolding as you roll. Breathtaking vistas that stop you in your tracks.
Coffee stops and camaraderie. Route prep and weather checks. Rain breaks and sunny bursts. Mad dashes. Racing each other to the top. And then kicking back...
It's about time — and it's about leaving time behind. Tuning into tranquillity. And shifting into oneness.

THE SCIENCE OF SPEED
With great speed comes great responsibility. That’s why we took a holistic approach that was 100% performance-focused in our quest to make the new ULTEGRA group even faster. Whether competing in local club races, trying to beat your personal best or riding for the pure enjoyment and camaraderie, our new 12-speed road group offers unparalleled control and comfort – all day and every day. This is the Science of Speed. And it’s what sets Shimano apart.

CLEANER COCKPIT
A sleek new wireless cockpit brings simplicity, clean aesthetics, improved ergonomics and easier maintenance. This is thanks to the new wireless system we developed to make shifting even faster — without compromising on precision and reliability. Road cycling never felt so good.

LIGHTNING-FAST CONTINUOUS SHIFTING
Shimano’s lightning-fast shifting innovation brings an uninterrupted and intuitive experience to road cycling. Game-changing HYPERGLIDE+ technology lets you climb, sprint, or cruise without stopping to think about your next gear change. The new Di2 shifting system uses our exclusive wireless technology to deliver the fastest, most accurate shifting on the market. And battery life is also best-in-class – the centralized internal battery delivers approximately 1,000 kilometers of worry-free riding on a single charge.

WORLD’S MOST INSPIRED DRIVETRAIN
The ULTEGRA R8100 group is our fastest, most inspired drivetrain at this level and packed with innovative game-changing features. HYPERGLIDE+ technology comes to road cycling for the first time. The new Di2 shifting system introduces our exclusive wireless integrated circuit. Meanwhile, the move to a 12-speed cassette ensures you’ll have all the gearing range you need. New to ULTEGRA, the power meter brings Shimano power data precision to a new, more approachable level. Ergonomics and aerodynamics have been enhanced at every turn. And, of course, you can set up the drivetrain just the way you like it via Shimano’s user-friendly E-TUBE app.

OPTIMIZED BRAKING CONTROL
Quieter and smoother, the new ULTEGRA braking system means you can enjoy even more precise modulation and stopping control on every ride thanks to Shimano's proven SERVO WAVE ACTION technology and enhanced brake lever ergonomics. Easier to maintain, the completely redesigned hydraulic disc brakes balance speed control and stopping power like never before. While the new design of the brake calipers minimizes brake rub. A tour de force in braking, ULTEGRA lets you focus on the next sprint, the next descent or conversations with your riding buddy.
