Ritchey Frameset Road Logic Disc Green With White Logo

Steeped with more than 50 years of frame-building heritage, innovation, exploration, and lots of riding, the classic lines of this beautiful steel frame and carbon fiber fork unite with modern building techniques and proven materials to deliver a contemporary bicycle that’s wonderfully comfortable for long days in the saddle, nimble and stiff enough to win the sprint for that sign, and adequately adaptable to endure roads that might lack proper pavement.

The Road Logic Disc frame is built with a heat-treated and triple-butted Ritchey Logic tubeset designed specifically for the Road Logic. It features aggressively short-butted sections optimized for TIG welding that save weight and improve ride quality. The frameset also includes a Ritchey WCS Carbon Road Fork for precise handling and responsiveness.

Updated for 2024, this modern classic now sports compatibility with Shimano’s newest Di2 semi-wireless groupsets. A new drive side dropout design allows for concealed wire routing from the battery in the seat tube, through the bottom bracket area into the chainstay where it makes a stealthy exit to the rear derailleur. But mechanical shifting fans, rejoice - the Road Logic Disc frame retains cable stops for mechanical groupsets. On the non-drive side chainstay sits a new one-piece truss design for flat mount brakes - providing as much stiffness and strength of previous mounts while reducing chainstay weight significantly.

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