Shimano Dura Ace
Shimano Dura Ace is the World's foremost performance groupset. The latest Dura Ace groupset, the 10 speed Dura Ace 7800, has set new standards in shifting performance and component efficiency. Already recognised as the smoothest shifters availble, Dura Ace 7800 shifters have been designed to be even more ergonomic. The awesome Dura Ace 2 piece chainset is already a design classic, offering an unrivalled power transfer via an oversized axle and outboard oversized bearings. The Dura Ace brake calipers are designed specifically for the front or rear of the bike, focusing extra power on the front. Of course, Dura Ace 7800 is one of the lightest groupsets available with weight saving features such as titanium sprockets and cold forged alloys. Shimano Dura Ace is now available with a wheelset befitting its quality, the WH7800 blends aerodynamics and lightweight for an all round capability. Whether racing or recreational, Dura Ace sets the standard in performance and reliability.
