Ritchey Road Logic Disc Frameset

Description

The Ritchey Road Logic Disc delivers an amazing ride experience combined with the stopping power and control of disc brakes. Steeped with more than 40 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 frame is built with a heat-treated and triple-butted proprietary Ritchey Logic tube set and features a straight headtube and aggressively short-butted sections optimized for TIG welding that save weight and improve ride quality. The tried and true specs on the frame remain unchanged but now sport a redesigned chainstay for flat-mount disc brake compatibility, thru-axles in the front and rear and a new fork designed specifically for the Road Logic Disc.
