Author CHARISMA 55i Road Bike Red 55 cm

The Author CHARISMA 55i is a lifestyle-oriented carbon road bike created for those who ride not only for distance, but for passion. Its Toray T700 carbon monocoque frame offers an exceptional balance of lightness and rigidity, while its aerodynamic silhouette glides effortlessly through the wind, giving every ride a sense of grace and precision.

Powered by the SHIMANO 105 Di2 electronic groupset, this bike delivers seamless shifting and perfect responsiveness on any terrain. Combined with SHIMANO R7170 hydraulic disc brakes, it offers powerful control and confidence whether you’re climbing, sprinting, or descending.

Rolling on MAVIC Ksyrium SL Disc UST wheels wrapped in VITTORIA Zaffiro Pro V 700x30c tires, the CHARISMA 55i provides flawless stability, smooth rolling and incredible efficiency. Premium finishing details — from the FSA A-Wing Pro handlebar to the Ritchey Comp Carbon Zero seatpost and Prologo Dimension SPACE saddle — create a perfect harmony of comfort, performance, and design.

The CHARISMA 55i isn’t just a bike — it’s an experience. A statement of freedom, precision and timeless style, built for riders who see the road as a place to express themselves.
