Shimano Dura Ace Components

9 results

Dura-Ace represents the pinnacle of Shimano's groupset hierarchy. It was first introduced by the Japanese component maker in 1973 and has since gone on to become a firm favourite of WorldTour riders and amateurs alike. Introduced as up-to 6-speed, through refinement of its production process over the decades, the latest iterations offer a mountain-flattening 12-speed. Of course, performance has improved in this time too. These days, these premium groupsets offer crisp and quick-as-a-flash electronic shifting, unrivalled performance, and hydraulic braking. So whether it’s a chainset, Di2 shifters, or a replacement chainring explore the range at ProBikeKit.

Engineered For Speed

Adorning the bikes of numerous road-racing champions, Dura-Ace has been engineered for speed. Indeed, speed, according to Shimano, was the ‘driving force’ behind the R9200 series. As well as being faster than ever, the latest series looks cleaner than ever too. The Di2 shifters now work semi-wirelessly, so that the cockpit is free from wires. Not only is this tidier looking, but with less things hitting the air it’s also faster. The front derailleur has also been refined further for speed. The frontal profile has been reduced 33%, saving you yet more watts. Although these differences might total up to a fraction of a second, for a groupset used by pros at the highest level of the sport, a fraction of a second may be the difference between winning and losing.

All the Tech

Integrating Shimano’s Hyperglide+ technology, shifting is now faster than ever. Introduced to the brand’s mountain bike groupsets, Hyperglide+ ensures better chain engagement and retention, translating to being able to more effectively change gears on varied terrain.

Hollowtech II technology is incorporated into the crankset. Hollowtech II is the brand’s way of keeping weight down, while maintaining strength and stiffness. What’s more, cranksets are now offered in a wider range of crankarm lengths, enabling you to get the perfect fit for you.

It’s almost a necessity in modern cycling to train with power. Optionally, Shimano offer integrated dual-side power meters into the R92000 crankset. The waterproof design, rechargeable battery, and <1.5% accuracy makes this an ideal training companion for training and racing.

If all that isn’t enough. Fear of being stuck in your biggest gear are kept to a minimum with 300 hours of battery life on offer; you’ll be able to conquer even the steepest of ascents with the option to fit an 11-34-tooth cassette; and the hydraulic-braking system has been improved to provide more powerful, consistent braking performance than ever.

As you would expect, Dura-Ace groupsets demonstrate high-quality construction, which is both incredibly durable and reliable. So, whether you're building your next performance road racer, or a neo-classic retro build, shop the huge range at ProBikeKit.
