Pinarello Sigma Sport Exclusive Dogma K8-S Road Bike 51.5cm
A 'game-changer' used by Team Sky to tackle the cobbles of Paris-Roubaix and Flanders, the Pinarello Sigma Sport Exclusive Dogma K8-S Road Bike 51.5cm has been designed to reduced the psycho-physical stress of an athlete over the roughest terrain.
Virtually compliant yet stiff, the front triangle is similar to that of the Dogma F8, however, the rear triangle features Pinarello's suspension DSS 1.0 (Dogma Suspension System) and new flat FLEXSTAYS™. The DSS features an elastomer suspension damper at the top of the seatstays, adding 10mm of travel. In testing on the Paris-Roubaix route, the Dogma K8-S showed a 4.6% improvement in handling and comfort over its predecessor, the Dogma K. With a size 53 frame weighing in at just 990 grams, this revolutionary design has little impact on the overall weight.
The Mavic Ksyrium Pro Exalith SL clincher wheels are a great all-round option, featuring the supreme stopping power of the Exalith braking track. Finished off with Challenge Paris Roubaix Open Road clincher tyres in a 27mm width, you can be sure of the best puncture protection and low rolling resistance.
Shimano's Dura-Ace Di2 groupset offers supremely smooth and reliable shifting and powerful braking. The combination of a 52/36 chainset and 11-28 cassette provides a wide choice of gears for spinning up mountains, tackling steep descents and sprinting on the flats.
Features
- Stiff yet compliant Pinarello Dogma K8-S carbon frameset
- FLEXSTAY™ chain stays and DSS 1.0 (Dogma Suspension System) for 10mm of travel
- Mavic Ksyrium Pro Exalith SL clincher wheelset and Challenge Paris Roubaix Open Road clincher tyres are perfect for smoothing out rough roads and cobbles
- The Shimano Dura-Ace Di2 groupset is the pinnacle of electronic shifting, allowing you to shift up or down in a split second
Please note: This is an ex-display, built bike available only in a size 51.5cm. It has been displayed in our Hampton Wick store, is in new condition and has not been ridden, but may have the odd scuff from being on display which is reflected in the price.
