All too often corners are cut to meet price-points in the entry-level road bike market but the Allez redefines what it means to be 'entry level.' Focusing on weight refinement and reliability like nothing else in its class the Allez is the first to make these technologies accessible to everyone. Whether you're just getting into road cycling commuting or looking for a new bike the Allez is just as performance-packed as it is versatile For the build this Allez features SRAM's Rival 22 shifting that delivers tremendous performance and value durable DT R460 alloy wheels our new super-comfy Body Geometry Bridge saddle and well-protected RoadSport tires. Not only does a lightweight bike feel better when you're climbing up a hill but it's also essential when you're carrying your bike up to the 5th floor and this was at the forefront of the frame design. With a redesigned E5 Alloy frame the Allez features a class-leading weight. Aggressively thin-walled yet tough tubes have been implemented to save weight and this results in over a 450g (1-pound) reduction in the frame and fork alone when compared to some models of yesteryear. Entry-level road bikes often times feature either alloy or cheap carbon fiber forks that greatly detract from the overall ride quality. But with a full FACT carbon fiber fork the Allez is better handling smoother riding and lower in weight—floating over rough chip-seal and carving through corners like a slalom skier. For the geometry we developed the Allez by utilizing our vast Retül fit database. This meant creating a geometry that's sure to cover a broad range of positions while still providing the performance-minded handling you'd expect from your first bike. This Allez also features integrated rack and fender mounts allowing you to get weight of your backpack off you and onto a lightweight rack. This not only makes for a good road bike but it also enables you to transform it into a fast commuter.

Why should you be forced to choose between aerodynamics and weight between ride quality and speed? It’s simple you shouldn’t. Enter the new Tarmac—climb on the lightest bike the UCI allows then descend on the fastest. We’ve utilized our most advanced technologies from our FreeFoil Shape Library to an all-new Rider-First Engineered™ frame to deliver a race bike that is truly without compromise. The days of making sacrifices between “aero” and “lightweight” bikes are over—the all-new Tarmac is the fastest race bike ever. One bike to rule them all. This S-Works Tarmac Frameset is the perfect canvas to begin your dream build. Build your totally-custom dream bike and be ready to ride fast. “Aero is everything”—we’ve been preaching it for years and it’s still the driving force for the new Tarmac. In our quest for tube shapes that deliver the fastest frame that the UCI rules allow we took a page out of the Venge development book and utilized our FreeFoil Shape Library. Armed with a library of optimized shapes we turned to the Win Tunnel to plug these shapes into a modular test bike for more testing and validation. The result? A new Tarmac that’s the fastest we’ve tested—45 seconds faster over 40km than the Tarmac SL6 (built with Aerofly II handlebars sold separately). No compromises just pure speed. While aerodynamics were paramount to the Tarmac’s development and to the development of all of our race bikes weight was the co-pilot on this optimal race bike journey. Previously “aero bikes” always compromised in the weight department—the more drag you reduced the more weight you gained. With the new Tarmac our design philosophy was to keep it at or below the UCI weight limit out of the box with no sacrifices to aerodynamics. And with the help of the FreeFoil Shape Library tools like isotopic FEA analysis and some engineering wizardry by the best engineers in the industry we delivered a frame that weighs a mere 800 grams without giving up a gram of aero stiffness or ride quality. Continuing our quest to develop the perfect race bike we used our Rider-First Engineered™ philosophy to ensure that the new Tarmac is the most balanced best handling Tarmac yet—no matter the size. With an army of the world’s best test riders from our three World Tour Teams — Boels-Dolmans Deceuninck-Quick-Step and Bora-hansgrohe — we made changes to the Tarmac based on their thousands of kilometers on the road. We balanced the ride quality between the front and rear end so even the longest days in the saddle continue to be comfortable—all without giving up anything to the Tarmac’s legendary handling and race-winning snappiness. Building on the learnings from the Venge the new Tarmac utilizes simple integration to create a clean fast cockpit that’s easy to live with. We’ve improved the routing for any configuration — mechanical shifting traditional stems round bars etc. — all while keeping its aerodynamic attributes. These same traits also make the new Tarmac easy to work on and easy to travel with. It’s a win-win.
