Frameset Ritchey Road Logic Disc vel. 57cm - Test

Product description

Steeped in over 50 years of frame-building heritage, innovation, and endless riding, the classic lines of this beautiful steel frame and carbon fiber fork unite with modern building techniques and proven materials. The result is a contemporary bicycle that is wonderfully comfortable for long days in the saddle, nimble and stiff enough to win a sprint to the sign, and adaptable enough to handle roads that might lack proper pavement.

Innovations and Proven Materials

The Road Logic Disc frame is built with a heat-treated, triple-butted Ritchey Logic tubeset, designed specifically for this model. The tubes feature aggressively short butted sections optimized for TIG welding, which saves weight and improves ride quality. The frameset also includes a Ritchey WCS Carbon Road Fork for precise and quick handling.

2024 Updates: Di2 and Mechanical

For 2024, this modern classic has been updated with compatibility for the latest semi-wireless Shimano Di2 groupsets. A new dropout design on the drive side allows for concealed wire routing from the battery in the seat tube, through the bottom bracket area, and into the chainstay, where it makes a discreet exit to the rear derailleur.

Mechanical shifting fans, however, need not worry—the Road Logic Disc frame retains cable stops for mechanical groupsets. On the non-drive side, a new one-piece truss design for Flat Mount brakes provides the same stiffness and strength as previous mounts while significantly reducing chainstay weight.

With its thoughtful design, unyielding attention to detail, and modern features, the new Road Logic Disc delivers an amazing, almost telepathic ride experience unlike any other bike. It's fast, nimble, comfortable, and perfectly suited for wherever your rides take you.
