Pinarello launches new, slimmer Dogma F, complete with “aero-keel” and a lifeline for rim brake lovers
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 group because the Dogma with Team Sky and latterly the Ineos Grenadiers. This is the 13th Dogma since 2005, and has been designed each with and for the nominally British group.
The element photographs that featured in my bumper Dauphiné tech gallery appeared to point out fairly marginal modifications on the floor, which is not a nice shock from a model that has such a distinctive silhouette for its flagship machine. It’s secure to say the beneficial properties are marginal, as is befitting a bike for a group that pioneered marginal beneficial properties as a idea, however marginal or not, some attention-grabbing issues are occurring.
Headline figures
For these of you tight on time, the quick model of all of the textual content beneath is that the brand new Dogma F is 108g lighter, has a new cockpit (which accounts for just below half of the burden financial savings), an ever so barely longer wheelbase, 30c tyre clearance, and is simply obtainable with prime spec groupsets, or as a frameset. Aero beneficial properties are there, with a 0.2% enchancment within the drag coefficient, however this is not a large 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 assessment.
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 edges as earlier than.
As effectively as narrower the top tube has been made deeper, although little was fabricated 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 similar 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, but it surely’s fairly large.
Both drive-side dropouts at the moment are blind, which is claimed to assist each aerodynamics and aesthetics. The geometry is in most respects an identical to the previous mannequin, however the fork has been given a longer rake (as much as 47mm from 43mm). This new kind 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 could equate to a saving of lower than a watt whereas driving 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 tendencies. I put this to Pinarello R&D supervisor, particularly within the context of the tendencies 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 group was keen to sacrifice for the sake of 1 race. We all know there’s all the time room for a little greater than the quoted most anyway, and given we noticed the group 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 much less bulbous than the older mannequin. This narrowing and slimming makes the cockpit 40g lighter, although it’s unclear what the burden financial savings are if you happen to account for a comparable width on the hoods.
The flare can be designed in such a method 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 accessible 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 additionally the usage of a greater modulus carbon in discrete areas of the layup, primarily across the backside bracket and chainstays. Higher modulus carbon is stiffer, so you should utilize much less of it to avoid wasting weight, but it surely’s extra brittle so it might probably solely be utilized in much less intricate areas.
Specs and pricing
The new Dogma F can solely be bought with prime finish groupsets, until 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 measurement 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 is going to doubtless not promote in as better quantity it is going to doubtless be a goal for rim brake aficionados, or anybody who’s written off a beloved rim brake body and has a completely useable rim brake groupset and wheels kicking about.
