Despite its position near the recreational end of Colnago's 2015 lineup, we feel that the AC R Disc Ultegra Complete Bike only has one noticeable barrier preventing it from riding in the WorldTour: disc brakes. Most industry insiders believe disc brakes won't be road legal in the Euro peloton until 2016, but other than that this bike's responsiveness and Shimano Ultegra drivetrain mean that your ride will feel like a professional machine while in motion, but will surpass the peloton's bikes in braking control. Self identifying as Colnago's entry level frame doesn't meant that the AC R is built with cheap, run of the mill carbon. In fact, the carbon comes from the same mill as that featured in the world beating C60: Toray's Japanese factory. Toray also has operations in China and elsewhere, but the carbon produced in Japan is the most consistent in the world. It's guaranteed perfect, every time, which is why in addition to Colnago's C60, V1 R, K Zero, etc., frames it's the only material Boeing will use in its aircraft. This carbon is so sought after that Toray enjoys a degree of selectivity in who they sell it to, so Colnago is the only cycling manufacturer able to use it for 100% of its frames. The AC R shares almost the exact geometry of Colnago's retired M10, which was the Italian manufacturer's flagship monocoque frameset before the advent of the all new V1 R. The M10's geometry was built for racing in the European peloton, and the AC R doesn't disappoint in this regard. It's got the same tight wheelbase for a frame that responds quickly without undercutting the ride with a twitchy feel. It'll inspire such confidence on descents that you'll quickly eclipse your current fastest times on descents, but the head tube is short enough that the front end can be slammed to satisfy the most critical of crit racers. Whatever your application, the AC R Disc Ultegra is equal to it. As you'd expect from a Colnago, the AC R also places a premium on comfort with..
