Cervélo S5 Bicycle – The Fastest Road Bike of the Modern Era
Designed to dominate every sprint, the Cervélo S5 is the evolution of the ultimate aerodynamic road bike. Used by athletes such as Wout van Aert, Marianne Vos, and Christophe LaPorte, the S5 has proven its superiority in the World Tour. At the 2022 Tour de France, it helped Van Aert achieve the highest points classification score of the modern era, thanks to its aerodynamic efficiency and responsiveness in every condition.
Speed Without Compromise
The new Cervélo S5 reduces aerodynamic drag by 65 grams and increases the frame surface area without adding weight. The frame shapes have been optimized according to the new UCI regulations, while the V-shaped handlebar stem has been refined to improve handling and simplify fit adjustment. The result? An aerodynamic, aggressive, and highly performing road bike.

A Complete Guide to Bike Sizes
Foreword: Not all bike sizes are the same
Each type of bike has a specific frame and often uses a different size scale. For example, a road bike with a 54cm frame might be considered a medium size by one brand, but a large by another.
Bicycle adjustment margins
Some types of bikes, like gravel bikes, offer a wide range of adjustments, adapting to different body types. Other models, however, have limitations in this regard. This is an important aspect to consider.
