Pinarellos new Dogma X is described as the ultimate all-road bike, engineered for riders who live for long days in the saddle.The Dogma X is positioned at the very premium end of the Pinarello range, sitting alongside the Dogma F as ridden by Netcompany-Ineos and Tom Pidcocks Pinarello Q36.5 team.That means its built from the same Torayca M40X carbon fibre and shares lots of aero-shaped tubing with the pro tour bikes. The new Pinarello Dogma X is the Italian brand's ultimate endurance bike. Roby Bragatto / Pinarello Improvements have been made over the original Dogma X, with a refinement of the iconic X-stay seatstay design. The 4-point split stays have been reshaped and attach to the seat tube lower down.Pinarello claims this leads to greater dispersion of vibrations, yet the lower connection also means minimising rebound as the carbon flexes, bringing a more controlled ride while still being compliant over poorer surfaces. The Dogma X's signature 4-point seatstays have been lowered and the shape refined. Roby Bragatto / Pinarello Aerodynamic enhancements The new down tube is tapered and aero-shaped. Roby Bragatto / Pinarello Using the aerodynamic knowledge gained from the development of the Dogma F, Pinarello has introduced aero elements to the endurance-focused X.A new elliptical steerer tube is designed to guide the brake hoses internally, in combination with a wider head tube Pinarello claims brings improved torsional stiffness and enhances the aerodynamic efficiency.The down tube has also be redesigned with a narrower tapered shape that brings down the drag yet increases lateral stiffness. Pinarello says this makes for a more reactive bike on the climbs that's faster through more efficiency on the flat.Small aero updates such as the enclosed dropouts on the fork tune the airflow, and the surface shaping throughout the new frame and fork are claimed to aid stability at speed. The increases in stiffness improve handling on descents, according to Pinarello. The rear dropout is now UDH-compatible. Roby Bragatto / Pinarello Along with the raft of design and aero improvements come all the modern details wed expect, with the rear dropout switching to UDH and tyre clearances upped to 35mm.Pinarello Dogma X range and pricing detailsThe Dogma X is available in 11 sizes, all with geometry adjusted to suit.

It's a shame it isnt going to come close to the average riders budget, though. The Pinarello Dogma X: yours for 12k+ Roby Bragatto / Pinarello Prices start at over 12,000 / $15,000 and thats before you go down the route of any personalisation or customisation through Pinarellos online MYWay programme. Frame only RRP: 5,500 / $7,250 / 6,700 / ZAR 134.000 / CHF 6.550 Full-build options from RRP: 12,500 / $15,750 / 14,900 / ZAR 298,000 / 14,600 CHFHopefully, Pinarello will take the interesting elements of the new Dogma X and build a more price-conscious option as it did with the F-series after the Dogma F.Until then, Im afraid that for me and most riders the idea of a 12,000 / $15,000+ endurance bike will remain a pipe dream.
