Driven by speed and the thrill of competition, these diehard riders and racers won’t settle for anything less than the lightest, stiffest, and fastest bikes on the road—whatever it takes to secure the win.
How do you build the world’s fastest road bike? First, it needs to be light. Exceptionally light. It needs a frame that delivers unparalleled torsional stiffness to transfer maximum power from the rider to the road. It needs razor sharp handling for precise and accurate cornering, helping you maintain speed when entering and exiting a corner. It needs to be smooth, yet maintain a distinctive “road feel” allowing you to perceive every control elements from the traction holding the tires to the accuracy of the steering. So how do you build the world’s fastest bike? You build a Tarmac. Proven in test labs and on the race course, nothing is faster, lighter, and stiffer.
The new S-Works Tarmac is Rider-First Engineered™ to provide every size frame with the hill-destroying stiffness and legendary descending prowess the Tarmac is known for. Having perfected the competitive geometry with previous generations, it improves on details like the ultra-stiff Cobra Head-tube, internal cable routing for mechanical or electronic to create a no compromise race-bred machine.
When we in the bike world talk about a bike’s “stiffness” it is important to know we are primarily referring to the bike’s torsional stiffness, not its ability to handle vertical vibration. Torsional stiffness refers to the frames resistance to flex when you push hard on the pedals and handlebars when accelerating or climbing, or pushing the frame in and around corners. This means a very torsionally stiff frame delivers an exceptionally fast, responsive, and exciting ride.
A bike with vertical stiffness is not as nice to ride, as it has more difficulty holding traction in bumps, feels less confident when cornering and descending at speed, and is more physically demanding of its rider. Creating a bike that is torsionally stiff yet delivers a smooth “ride quality” like the Tarmac is no easy feat, and is the direct result of Specialized’s own innovations in carbon frame design, engineering, construction and working directly with the people who ride these bikes every day.
