Gan GR-S Disc Ultegra Complete Road Bike - 2017

For 2017, Pinarello joins the all-road endurance party with its Gan GR-S Disc Ultegra Complete Road Bike. With disc-specific construction, stiff thru-axles, and a proprietary suspension system, the Gan GR-S brings a rare mix of exceptional comfort, classic Pinarello aesthetics, and efficient speed to your next off-pavement adventure. Built up with Shimano's smooth-shifting Ultegra drivetrain and hydraulic brakes and rolling on Fulcrum Racing wheels wrapped in Vittoria's trusty Adventure tires, this bike is ready for almost anything.

The Gan Disc features similar eye-catching styling as the top-tier Dogma KS-8, with its signature curves and unique elastomer suspension system. This suspension, 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 composition of the elastomer, but it claims that this system effectively dampens vibrations without experiencing excessive movement when riders dump watts into the pedals. Slightly flattened chainstays and seatstays provide additional compliance over the bumps while maintaining lateral stiffness.

The most notable difference between the Gan GR-S frame and its high-end cousin is the type of carbon used to make them. While the Dogma KS-8 boasts the top-end of the top-tier Toray T1100 1K Dream Carbon and the Gan S is made of T700 carbon, the Gan GR-S consists of slightly more compliant T600 carbon, which gains weight and sacrifices a tiny bit of stiffness but drops the overall cost significantly. While this carbon is slightly less rigid than the T1100 1K, it remains a high-strength, race-worthy layup designed to handle hard miles over varied terrain. It's every bit as light and stiff as the bikes that many of our cycling heroes (Ulle, Museeuw, Tommeke, etc.) rode to grand tour and monument wins. We should also note that, like most cycling fans, we still lust after those bikes even as technology pushes ever further into the future.

Those tech advancements have come to include aerodynamic considerations. The Gan GR-S isn't called out as specifically aerodynamic, but it inherits Pinarello's signature oval-front and flattened-back tube shaping throughout the frame and fork, creating an aerodynamic profile that slices cleanly through the wind without any extra materials bogging down the scale. An integrated seat clamp and aero seat post add to the wind-cutting advantage and offer clean, uninterrupted frame lines.

Pinarello Gan GR-S Disc Ultegra Complete Road Bike features carefully engineered internal cable routing compatible with both mechanical and electronic shifting systems for an added dose of aerodynamics and crisp, clean lines for any setup. It's finished with a threaded Italian bottom bracket that does away with PressFit's creak and longevity issues, a trend that we're happy to see resurfacing across the industry.
