Pinarello Dogma F8

The 2015 Pinarello Dogma F8, available from Lakeside Bicycles.

What do Pinarello and the supercar engineering people at Jaguar have in common?  Outside of joint sponsorship of team Sky, very little.  Until now.....

When, after yet another Tour de France victory (yawn) it became time for a ground up re-design of the Dogma 65.1 Think2, Pinarello was faced with a quandary:  "How do you improve on perfection?"  In time tested Pinarello fashion they offered Jaguar the opportunity to add a little luster their (non-Italian) lineage.  When test results of the new frame came in, they spoke for themselves.  By applying material upgrades and new tube shapes and designs the F8 (8th generation Dogma)  improves aerodynamics by 47%, balance by 16%, rigidity by 12% and reducing weight by 120 grams, all without sacrificing the Think2's geometry, handling or comfort.  The future of Italian road bikes is here.Pinarello Dogma F8, better in so many ways!

Japanese carbon fiber specialists, Toray, again provide the substrate for a Dogma.  The 65HM1k Nano-alloy Carbon Fiber used in the Think2 exceeded the performance specifications of anything previously found in a bicycle frame, imagine the efficiency when Torayca T1100 1K Dream Carbon Nano-alloy finds it's way into the F8.  Previously only found in the outer skin of ultra-high tech aircraft, T1100's stiffness-to-weight is otherworldly.  Compared to the 940 gram 54cm Think2, the same sized F8 weighs nearly 80 grams less with no loss of strength.

Using the Think2 as a baseline, Jaguar engineers employed Computational Fluid Dyanmics (CFD) to evaluate more than 70 frame designs through over 300 CFD analysis cycles in the design of the F8.  What resulted were Pinarello's new "FlatBack" tubes.  In cross-section FlatBack has an ovalized frontal section paired with a truncated rear increasing turbulent flow at the back of the tube to act as a sort of aerodynamic bearing and, counter to intuition, reducing drag.  An ideal aerodynamic tube profile has an 8 to 1 length to width ratio, Pinarello was able to maintain a UCI allowable 3 to 1 ratio on the front half of the tubes without an un-aerodynamic oval rear profile.  The result is a profile that maintains the strength, rigidity and ride quality of the Think2 while dramatically improving the F8's aerodynamics.

The design of the F8 boasts improved integration of the fork with the tapered 1 1/8 to 1 1/2in streamlined head tube and over sized FlatBack down tube.  Pinarello engineers saw no reason to compromise reliability and rigidity at the bottom bracket and have stuck with an (ironically) unconventional threaded Italian BB.  The F8's asymmetric chainstays are paired with the new Onda RS F8 seatstays, which meet the seat tube farther down and are more concave than in the Think2. This also masks the rear brake and, along with the new TwinForce integrated seatpost clamp, improves aerodynamics at the rear of the bike. The CFD analysis also showed that lowering the seat tube water bottle mounts resulted in lowered drag, so Pinarello has added a third riv-nut to allow two water bottle positions.

Pinarello continued to polish asymetric frame design in the Dogma F8.  Their engineers again applied Finite Element Analysis (FEA) to further study the forces in action as a rider sprints pulls on the handlebars, and muscles the bike through corners.  The results confirmed the bennefits of asymmetric design and eventually lead to greater asymetry (16% more) in the F8 than in the Think2 thereby improving the balance of forces across the frames center line.

As with the Think2, the F8's cable routings accommodate either electronic or mechanical shifting with no compromise in aerodynamics or aesthetics.  The F8 also features interchangeable cable stops which can be readily adjusted to accommodate different drivetrains.  With proper mounting hardware (sold separately) the Air8 seatpost accepts both Shimano Di2 and Campagnolo EPS battery packs.
