Description

Conquer the cobbles.

Suspension and disc brakes are things you'd typically only find on bikes designed to be ridden in the dirt. That's all changing with the influx of disc-equipped cross bike, a trend towards all-road capability, and a continued push to make the cobbled classics a little less jarring on pro tour bodies. Enter the 2017 Pinarello Dogma K8-S Disc Road Frameset. Born from collaboration between Pinarello and the same Jaguar supercar engineers who helped design the legendary Dogma 8, the K8-S Disc pairs Pinarello's unique rear suspension with disc brake compatibility to set a new standard for rough road ability.

Pinarello again relies on Japanese carbon fiber supplier Toray for the K8-S frame's material. It features Torayca T1100 1K Dream Carbon with Nano-alloy technology, which is the same material used in the Dogma F8. While the name is certainly impressive, its application is even more so. T1100 1K is the current go-to outer skin for many modern aircrafts, and its stiffness-to-weight ratio is nothing short of stunning. But weight, of course, is only a slice of the Dogma equation; we all know tube shaping also plays a vital role in the bike's handling and overall efficiency.

Starting at the front of the frame, Pinarello utilizes its Onda Disk fork, which has slightly more rake than the F8's front end to add a hint of additional compliance and stability. As with the F8's front end, the Onda fork is inspired by Pinarello's TT-specific Bolide, with an optimized surface profile that effortlessly manages airflow from the front wheel. The blades describe a somewhat convex, bow-legged shape, which Jaguar's engineers claim keeps air attached, reducing the size of the wake without creating too large a frontal zone.

The Dogma K8-S' front triangle closely mirrors the shape and aerodynamic profile of the Dogma F8. Pinarello incorporates its signature FlatBack technology with oval-front and flattened-back tubing throughout the frame and fork for an aerodynamic profile that slices cleanly through the wind without any extra materials bogging down the scale. As an extra touch, an integrated seat clamp and FlatBack seatpost add to the wind-cutting advantage.

All similarities to the F8 quickly disappear as you move to the rear triangle, with the K8-S utilizing a markedly different layout out back than the F8. Most noticeably, a small elastomer suspension system, dubbed the Dogma Suspension System 1.0, sits at the seatstay junction to provide up to 10mm of plush cushion to smooth out bumpy roads and cobbles without sapping away power. Pinarello is understandably secretive about the final shape and mix of the elastomer, but it claims that this system effectively dampens vibrations without experiencing excessive movement when riders dump watts into the pedals. The chainstays and seatstays on the K8-S have also been flattened compared to the F8 to provide additional compliance over the bumps while maintaining lateral stiffness.

At the bottom bracket junction, Pinarello sticks with its proven Italian-threaded shell, a design choice it stands by for both reliability and overall rigidity. Additionally, the extensive CFD testing revealed that lowering the seat tube water bottle mounts results in less drag. Because of this, Pinarello incorporates three holes on the seat tube and down tube for two bottle mounting positions.

Pinarello's Asymmetric design philosophy is ever-present in the Dogma K8-S, as its engineers again restudied the forces in action as a rider stands on the pedals, pulls on the handlebars, and muscles the bike through corners. FEA (Finite Element Analysis) confirmed that the Asymmetrical design was beneficial in leveling the variances in frame deflection from one side to the other, which is why the K8-S' tubes have been arranged in a similar layup to better balance drive-side forces.

As with the F8, carefully engineered internal cable routing on the new K8-S allows for you to easily choose between either mechanical or electronic shifting systems without any penalty to the bike's aesthetics or its aerodynamic profile. The K8-S features interchangeable cable stops at the frame openings that are capable of being intuitively swapped out should you select different drivetrains throughout the life of the frame.

Looks like the new 2017 model has thru axles that specify 12FX 12R axles. In trying to pair with ENVE wheels SES 5.6 the thru axles are 15F X 12R. Is there an adaptor for the front axle to pair these up, or are ENVE wheels just not compatible with this new frame design?

Hey Jack, the 5.6 is compatible with the 2017 frame set. It's a pretty quick swap with end caps on the DT 240 hubs.



Contact me at araines@backcountry.com or 801.204.4556 if you want to chat more about it.

Depends on which hubs your Enve wheels use. The DT 240 hubs have end caps available to fit everything.
