Introducing the Ritchey Road Logic Disc Frameset: Timeless Heritage, Modern Performance
The Ritchey Road Logic Disc Frameset epitomises the perfect fusion of classic road bike aesthetics and cutting-edge performance. Steeped in over 50 years of frame-building heritage, innovation, and extensive riding experience, this beautiful steel frame and carbon fibre fork deliver a contemporary bicycle that's wonderfully comfortable for epic days in the saddle, nimble and stiff enough for sprint finishes, and robust enough to tackle roads that might lack proper pavement.
The Road Logic Disc frame is meticulously crafted from a heat-treated and triple-butted Ritchey Logic tubeset, explicitly designed for this model. It features aggressively short-butted sections optimised for TIG welding, which expertly save weight while significantly enhancing ride quality. The frameset includes a high-performance Ritchey WCS Carbon Disc Road Fork for precise handling and responsiveness, ensuring a truly integrated and superior ride.
Updated for 2024, this modern classic embraces the latest technology. It now boasts stealth wire routing for Shimano’s newest semi-wireless Di2 groupsets (EW-SD300 compatible), with a clever drive-side dropout design for concealed battery and derailleur wiring. Mechanical shifting enthusiasts will rejoice, as the frame thoughtfully retains cable stops for traditional groupsets. On the non-drive side, a new one-piece truss design for flat mount brakes provides exceptional stiffness and strength while significantly reducing chainstay weight.
With purposeful design, unwavering attention to detail, and modern features like flat-mount disc brakes (140mm native, 160mm max) and 12mm thru-axles (front & rear), the new Road Logic Disc almost telepathically delivers a fantastic ride experience unlike any other bike. It’s fast, nimble, comfortable, and ideally suited for wherever your rides may take you.
The Ritchey Road Logic Disc Frameset is the quintessential choice for cyclists who cherish the nuanced ride quality of steel, demand the stopping power of disc brakes, and appreciate a bike that blends classic artistry with cutting-edge functionality.
