Ritchey Road Logic Disc Frameset - Green

The all-new Ritchey Road Logic Disc retains the exceptional riding experience the bike is renowned for while incorporating the superior stopping power and control of disc brakes. Drawing on over 40 years of frame-building heritage, innovation, exploration, and extensive riding, this elegant steel frame and carbon fiber fork blend classic aesthetics with contemporary construction techniques and trusted materials. The result is a modern bicycle that offers exceptional comfort on long rides, agility and stiffness for spirited sprints, and the adaptability to handle less-than-ideal road conditions.

The frame is meticulously crafted using a heat-treated, triple-butted Ritchey Logic tube set, featuring a straight headtube and strategically short-butted sections optimized for TIG welding, reducing weight and enhancing the ride quality. The frame maintains its proven specifications but now incorporates a redesigned chainstay to accommodate flat-mount disc brakes, as well as thru-axles in the front and rear. Additionally, a new fork tailored for the Road Logic Disc is introduced.
