Campagnolo strives to always offer the best solutions, no matter what frame or tire the cyclist has chosen. As manufacturers begin to develop frames and fork designs that take advantage of the aerodynamic gains of direct mount brakes, the Campy Tech Lab has worked to make new Campagnolo Direct Mount brakes that can guarantee the Campagnolo quality and performance standards. Through the self-balancing design, this new braking system by Campagnolo provides a completely symmetric and efficient brake application. In addition, the extremely stiff structure of the new Campagnolo Direct Mount brakes ensures superior stopping power, whilst the design elements take inspiration from the aerodynamics of the brake and are enhanced by the new sealed structure of the brake levers themselves. In addition to pure performance, a great deal of attention was given to ease of use and adjustment. The goal was to guarantee that the Campagnolo brake would be both easier to fit and intuitive and simple to adjust compared to any model available. That was made possible through the stiff structure positioned in the rear part of the brake, enabling rapid fitting that does not require external brake boosters, even on the weakest chainstays.

New Super Record 12 Speed sprocket cassettes: innovation which gives the user great advantages, thanks to the matching dimensions and complete compatibility with wheels and frames. The rider has always been Campagnolo’s focus, and the goal has always been facilitating their performance; making the impossible possible. Adding an additional sprocket might seem simple, however, we have not only succeeded in maintaining the same footprint, but also improving the component’s performance and durability, which was a tricky challenge! The new Super Record 12 Speed sprocket sets feature thinner sprockets, tighter spaces and space-saving dimensions that are the same as those of the 11 Speed sprockets, meeting everyone’s needs with just two (11:29; 11:32) cassettes. The addition of the twelfth sprocket allows a linear upshift or downshift by a single tooth, up to the seventh gear, allowing the cyclist to find the perfect ratio for any situation. In addition, the closer sprockets ensure faster, quieter and more precise shifting thanks to the special tooth design and surface treatment which guarantees a longer lifespan. The 6 larger sprockets are also available in two single-piece steel triplets, to avoid energy loss. Mounting the cassettes is easy thanks to matching-thickness spacers.

When you're racing against the clock, there's no room for mistakes, so Campagnolo's Record EPS TT Shift/Brake Levers ensure a perfect shift every time. In addition, flawless braking is always at hand thanks to the contoured, ergonomic carbon levers.
