Shimano have released a brand new version of their high-end Dura-Ace groupset, which is available to pre-order from Chain Reaction Cycles now!
Here are the headlines of the new Shimano Dura-Ace groupset:
It’s the first ever Shimano Dura-Ace group to include hydraulic disc brakes
There’s an integrated power meter
It’s still 11-speed
There are four versions – a mechanical rim brake version; an electronic Di2 version with rim brakes; a mechanical and electronic version with hydraulic disc brakes
The Global Cycling Network produced a fantastic overview of the new group, which you can watch here:
The objectives with the new group were to increase efficiency, improve integration and aerodynamics – here’s Shimano’s summary of the details…
Hydraulic disc brakes appear on Dura-Ace for the first time, and keeping with the aero theme, the calipers can be directly mounted onto your frame (flat mount) for a clean low profile design.
New dedicated Dura-Ace Freeza rotors deliver better heat management properties to provide stability in brake performance.
The FC-R9100-P is Shimano’s first pedaling power measurement product and also the first crank-integrated power meter on the market. It monitors real time power data to track and analyse your performance. It’ll integrate easily with third party display units to enable the most sophisticated and accurate level of performance measurement and anatomic analysis available today.
Not only can the pure output of watts be measured, left and right legs can be measured separately, as well as cadence, giving you the truest measure of performance, isolated from external factors such as gradient, road surface and wind.
Two braking options now exist for riders at Dura-Ace level: mechanical rim brakes or hydraulic disc brakes. Hydraulic road disc brakes in the new Dura-Ace line-up add an extra element of control and confidence to brake performance in tough (weather) conditions.
Dual-pivot or Direct Mount type rim brake calipers bring incredibly powerful performance, offering the best balance between rigidity, weight and stopping power, providing a sleek design, bringing better clearance for tyres up to 28c and a 43% reduction in flex over previous Dura-Ace brakes.
Direct mount options provide integrated aerodynamic designs at the front (BR-R9110-F), on the rear seat stay (BR-R9110-RS) or under the bottom bracket (BR-R9110-R).
In the meantime, BikeRadar have already had the chance to ride the new groupset and have posted an initial review.
