Pinarello & Jaguar work on rear suspension system for cobbled classics.

Rear suss for cobble-riding road bikes developed by Pinarello & Jaguar

Jaguar and Pinarello have co-engineered what they say is the "world’s first bespoke bicycle for hugely challenging terrains." Cobbles, that is. The Pinarello Dogma K8-S bicycle possesses a new lightweight suspension system and flexible flat carbon chain stays to create a suspension pivot in the rear triangle for comfort over rough terrain. , All eight Team Sky riders will ride the bike at the Tour of Flanders on Sunday 5th April.

The companies say they have created a bike with an overall performance increase of nearly 5 percent with a 50 increase in rider comfort over the previous Dogma K model.

“You realise the difference straight away, especially on the cobbles,” said Team Sky’s Sir Bradley Wiggins.

The reigning UCI World Time Trial Champion added: “I’ve never ridden anything like it on cobbles before, which is the most extreme terrain you can ride a bike on. The way it feels, its aerodynamics, stiffness, and improved flex in the rear, is game-changing for cycling.

“It was really noticeable in testing between the guys on the K8-S to the others that weren’t. It gives us lots of confidence and a huge advantage on the cobbles.

“The level of innovation and thinking outside the box, largely down to Team Sky and the automotive expertise from Jaguar, is streets ahead of other teams and manufacturers out there.”

Fausto Pinarello, CEO of Pinarello, said: “The Dogma K8-S absorbs only the necessary shocks of the road to allow you to keep pedalling regularly with optimum power and precision. It is the perfect bike for the cobbles.”

Sir Dave Brailsford, Team Sky Team Principal, said: “The Dogmas F8 was the first real breakthrough of [the partnership between Pinarello and Jaguar], and we’ve now taken it a step further. The Dogma K8-S is a significant jump in terms of a bike’s impact of performance. It’s rare for one small design innovation to make such a large difference – this is one of those situations."

The new bike has been subjected to several months of laboratory and practical tests, using accelerometers, powermeters and GPS instrumentation, to ensure rider safety and performance efficiency of the new frame.

In March, Sir Bradley Wiggins and Christian Knees, tackled the long and regular cobble sectors on the last 130km of the Paris-Roubaix route, where comparative tests were undertaken with the previous Dogma K frame.

“The experience Jaguar has developing vehicles over widely varying surfaces across the world has helped us to understand what may be required for cobbled surfaces,” said Tim Donovan, Vehicle Dynamics at Jaguar Land Rover.
