Shimano Dura-Ace represents the pinnacle of the Shimano groupset range. Because each component has been engineered to offer incredible performance that lasts, it's easy to see why Dura-Ace has been the group set of choice for World Tour riders for decades. While Shimano has updated the new iteration of the Dura-Ace group set to reduce weight, they've also managed to maximise efficiency and shifting performance. Plus, with a new stealthy design, the Dura-Ace 9100 is an excellent looking groupset and well suited any performance road bike.
Firstly, the new Dura-Ace crank has received a totally new redesign with a larger, stiffer alloy arm to help aid power transfer. However, thanks to the iconic HollowTech design, it's also immensely lightweight. Fortunately, this crank has also been optimised for use on disc brake road bikes which have bigger seat stays too. Additionally, with an enormous variety of chainrings sizes, Dura-Ace cranksets are well suited to a wide variety of terrains and riding styles.
Dura-Ace 9100 shifters have received an overhaul with improvements in ergonomics and comfort. With a textured rubber lever hood to improve grip and redesigned internals which offers a crisper shift, these new Dura-Ace 9100 levers offer comfort and performance in equal measure.
Employing Shadow technology from Shimano's mountain bike range, the Shimano Dura-Ace 9100 rear derailleur sits under the chainstay. As a result, this new derailleur offers a slimmer profile which improves aerodynamics and greater crash protection. Similarly, the new Dura-Ace rear derailleur has also been re-engineered to be smaller, more efficient and offer a cleaner, crisper shift. It is also equipped with an internal toggle mechanism which gives greater clearance for larger tyres. Now featuring a built-in cable tension adjustment bolt, there's now no need for inline barrel adjusters.
The new Dura-Ace brake callipers have also been redesigned to offer clearance for up to 28mm tyres while retaining the same aerodynamic performance of previous iterations. They're also up to 43% stiffer than previous brake callipers for incredible stopping performance, and provide a linear braking curve for improved feel and function.
Finally, the new Dura-Ace cassette offers the same reliability and ranges of previous iterations. Thankfully, it also comes in a 11-30T version, helping you attack steeper climbs with confidence. While the cassette is constructed with a lightweight carbon fibre spider that contains alloy sprockets, the largest five cogs are made of titanium to reduce weight even further. A new lightweight, hollow pin chain completes the groupset. With a PTFE coating to increases durability, this new chain provides both efficiency and a smooth shift that lasts.
