The Pinarello Dogma has been a peloton staple for years, and whereas the Specialized Tarmac rivals it for longevity, few different bikes have change into as synonymous with a single workforce because the Dogma with Team Sky and latterly the Ineos Grenadiers. This is the thirteenth Dogma since 2005, and has been designed each with and for the nominally British workforce.
The element photographs that featured in my bumper Dauphiné tech gallery appeared to point out fairly marginal modifications on the floor, which is not an incredible shock from a model that has such a particular silhouette for its flagship machine. It’s secure to say the features are marginal, as is befitting a motorbike for a workforce that pioneered marginal features as an idea, however marginal or not, some attention-grabbing issues are happening.
Headline figures
For these of you tight on time, the brief model of all of the textual content under is that the brand new Dogma F is 108g lighter, has a brand new cockpit (which accounts for just below half of the burden financial savings), an ever so barely longer wheelbase, 30c tyre clearance, and is barely out there with prime spec groupsets, or as a frameset. Aero features are there, with a 0.2% enchancment within the drag coefficient, however this is not an enormous enchancment in actual phrases.
For anybody eager to see how all that interprets into trip efficiency, you are in luck. Cyclingnews was invited to trip the bike forward of the launch, my first impressions are penned in my Dogma F first trip evaluation.
New frameset
The coronary heart of any new bike is the frameset, and the Dogma frameset has been fettled and tweaked slightly than overhauled. At the entrance, the headtube has been narrowed by 8mm to scale back the frontal space, facilitated primarily by the introduction of an oval steerer tube that creates house for the brake hoses to run down the entrance of the top tube slightly than the perimeters as earlier than.
As effectively as narrower the top tube has been made deeper, although little was made from this addition within the official presentation I used to be given on the launch.
To match the narrower head tube, the fork legs have additionally been narrowed of their particular person widths, whereas on the identical time being spaced extra extensively to simply accept bigger tyres – extra on this in a second. The downtube has additionally been narrowed barely.

At the underside, the underside bracket has been prolonged ahead to create what Pinarello calls an “aero-keel”. Hidden by the cranks it is probably not one thing I noticed a lot of in my preliminary photographs, however it’s fairly enormous.
Both drive-side dropouts at the moment are blind, which is claimed to help each aerodynamics and aesthetics. The geometry is in most respects an identical to the previous mannequin, however the fork has been given an extended rake (as much as 47mm from 43mm). This new type geometry had apparently been examined extensively on the outdated mannequin and was met with Ineos rider approval.
These tweaks, along with the brand new cockpit, have solely resulted in a CdA enchancment of 0.2%. Brands hardly ever quote aero enhancements when it comes to CdA, however in actual phrases, this might equate to a saving of lower than a watt whereas using at 40km/h.
Using some barely convoluted maths, Pinarello has claimed that this CdA enchancment is equal to a further 175g in weight financial savings over the size of a grand tour, ridden by Geraint Thomas.
Tyre clearance
The new Dogma F can now settle for 30c tyres, which is slightly slender when it comes to latest developments. I put this to Pinarello R&D supervisor, particularly within the context of the developments I noticed at Paris-Roubaix with groups operating 34c tyres and wider.
The response was indicative of the enter Ineos has on the bike. Simply put, permitting wider tyres than 30c would have resulted in a much less stiff backside bracket, and this wasn’t one thing the workforce was keen to sacrifice for the sake of 1 race. We all know there’s all the time room for somewhat greater than the quoted most anyway, and given we noticed the workforce operating 32c tyres on the outgoing Dogma F (which has a claimed most of 28mm) at Roubaix this 12 months, it is secure to imagine they’re going to proceed to do the identical.
New cockpit
The new Talon Ultra Fast cockpit is measured from the drops, that are flared by 1cm on both sides, so on the hoods, a 40cm is successfully a 38cm. The tops are narrower and fewer bulbous than the older mannequin. This narrowing and slimming makes the cockpit 40g lighter, although it’s unclear what the burden financial savings are in the event you account for the same width on the hoods.
The flare can also be designed in such a approach as to work with the brand new UCI guidelines on inwardly turned hoods. Given the oval steerer that is the one cockpit that may be run on the bike, and is offered in widths from 34-42cm and stem lengths of 80-140mm.
Weight financial savings
Nearly half of the 108g saving comes from the cockpit. The remaining 60g saving has come from slimming areas of the body (head tube and backside bracket) and in addition using the next modulus carbon in discrete areas of the layup, primarily across the backside bracket and chainstays. Higher modulus carbon is stiffer, so you need to use much less of it to avoid wasting weight, however it’s extra brittle so it could actually solely be utilized in much less intricate areas.
Specs and pricing
The new Dogma F can solely be bought with prime finish groupsets, except you go down the frameset route. Dura-Ace, Red, or wi-fi Super Record are the one choices. The wheel choices are equally premium, with Princeton Peak 4550 or DT Swiss ARC 1400 wheels paired with Dura-Ace or Red, and Bora Ultras with the Super Record choice.
System weights for a dimension 53 with out pedals and bottles are 6.63kg for Red w/ Princeton wheels, 6.77kg for Dura-Ace w/ Princeton wheels, and 6.88kg for Super Record with Bora WTO wheels.
Prices begin at €14,500 / £12,600 / $14,500, and a frameset will set you again €6,700 / £5,500 / $6,950.
A lifeline for rim brakes
To the shock of no one, the brand new Dogma F is a disc brake bike solely. What was a shock was the announcement that Pinarello goes to proceed to supply the rim brake model of the outdated Dogma F.
Yes, it is a tremendous premium frameset, however credit score the place it is due it is a win for backwards compatibility and whereas it can seemingly not promote in as better quantity it can seemingly be a goal for rim brake aficionados, or anybody who’s written off a beloved rim brake body and has a superbly useable rim brake groupset and wheels kicking about.
