It’s not often you think of a professional cycling team such as Team Sky as a matchmaking service, but that is exactly the role it helped play in the development of the Pinarello Dogma F8.

The Italian marque had a lot of help on the aerodynamics from another team sponsor, Jaguar.

But the question is, is the Dogma F8 the result of a match made in heaven or a marriage of convenience? Based in initial results, the former. On the bike’s debut, 12 days after launch, Chris Froome rode the Dogma F8 to victory on the Col du Beal in the Critérium du Dauphiné. That’s the sort of impact Pinarello and Jaguar pay good money for.

In our view the new Dogma F8 is a massive aesthetic enhancement on the outgoing Dogma 65.1; the stylised curvature in the 65.1 has been replaced by a design that looks far more purposeful and aggressive.

At the Dauphiné we got up close and personal with the Froome’s Dogma F8 to look at the technology and some of the customisation that’s crept into the Tour de France champion’s set up.

First up, the frame. Pinarello have developed a truncated aerofoil tube in new Torayca T1100 1k carbon. The tube profiles are dubbed FlatBack and are one of a number of aerodynamic enhancements around the frame, such as integrated seat post clamp, internal cable routing and even the position of the bottles on the bike (the seat-tube has three bottle holder fixings giving riders two mounting options, the lower one being more aero). However great care was taken to protect the ride characteristics of the bike – a specific request from the team apparently, and this 560mm frame matches the precise geometry of Froome’s previous 65.1.

The fork is a radically different from most road frames. It was lifted largely unchanged from the Bolide time trial bike and curves out in the legs to minimise air turbulence.

Much of the componentry on Froome’s bike remains similar to the 65.1 we saw at last year’s Critérium du Dauphiné. Electronic Shimano Dura-Ace componentry dominates. His use of Osymetric rings remains (the mechanics will be pleased) and they’re driven by a Dura-Ace 9000 crank.

There are some sharp touches to the bike. The face plate on the satellite climbing shifter is removed leaving the buttons exposed. Look inside the crank and Sky mechanics have fitted a make-do chain catcher to fill the void the K-Edge catcher can’t fill because of the oval rings.

Elsewhere Team Sky’s new sponsor Stages provide power measurement through their left hand crank system and a Garmin translates the readings.
