Think of the S5 frameset as a pure result of iterative design and a drive to explore the limits of bicycle aerodynamics. The previous generation was fast, but the current is faster, a bit lighter, more comfortable to ride and has a more lively feel. Speed is attained through impressively improved aerodynamics of the frameset, as well as how the frameset and an advanced aero wheel design interact with each other for more efficiency. This S5 design has reduced drag and increased the frame’s surface area while still reducing overall weight. The deeper frame sections maximize the shapes now allowed by the UCI. Cervelo was able to deepen their proven aero profiles and squeeze 65 more grams of drag performance out of what was already the fastest aero bike on the market. You’ll notice a deeper head tube and bottom bracket zone, as well as more aggressive shaping on the trailing edges of the tubes. Given that the S5 is only compatible with electronic shifting, the designers were were able to refine as small a detail as the rear dropout for an incremental gain, other small shapes and zones on the frameset.

One striking aspect of the last S5 was the proprietary triangular V-stem and handlebar system, which, in line with integrated internal cable routing also offered a cleaner aero front of the bike. The design was adjustable and modular, but complicated, due to integration of the stem and headset system with the proprietary S5 carbon fork. The engineers have cracked that problem, and the iconic V-stem has been further refined for simpler use and adjustment and a new fork been designed to simplify the entire front end of the bike. Now you don't require a top-level mechanic to make adjustments. The S5's V-stem not only inspires confident handling at high speeds, it's now also remarkably simple to dial in your perfect set-up. All the necessary spacers come with the bike, and there’s now only one bolt length, reducing complexity and making the system 53g lighter in the process. The handlebar itself has also been made sleeker, with better hand-to-lever transitioning and an easy 0-5° angle adjustment with infinite positioning within that range. You can truly find that commanding, aggressive racing posture you've always desired, and fully trust the strength and stiffness of the carbon modular assembly in every race application.

SRAM's 12-Speed Red eTap AXS HRD groupset is one of the lightest made, and this version features the chainring spider Quarq-designed AXS power meter. The 10T small cog of the cassette, in a 10-33T combination delivers deep road race range with a 45-38T chainring combination. Wireless, electronic eTap shifting runs along side the AXS (access) BLE system, with the encrypted AIREA system employed by the eTap components fully secure. The SRAM AXS App allows to monitor all battery levels and customize your shifting. Impressive performance is a given at this level, but Red AXS still exceeds all expectations.

The SRAM Red E1 components feature effortless one-finger braking, smooth front shifting, fully wireless connectivity, and expanded gearing choices to fit every rider. SRAM packed in every feature they could, like accurate and reliable power measurement, new shift points, and more brake adjustability, while still shaving weight off every component to bring you the lightest electronic groupset ever.
