The Road Logic Signature Edition offers a riding experience steeped in more than 50 years of life experiences, framebuilding heritage, innovation, and exploration. It's a legacy that traces back to the 1970s, when Tom Ritchey built his first road frame in his parent's garage in northern California. Since then, Tom has continued to explore, experience, and innovate in ways that define the craft, and the Road Logic Signature Edition is the result of that expanding legacy: his prodigious experience with steel, and mastery of the subtleties and details gleaned from his tenure in the art of creating bicycles.

The beauty of its classic lines unites with modern building techniques and proven materials to deliver a contemporary bicycle that's sufficiently 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. Bearing Tom Ritchey's signature on the top tube, it's a subtle reminder that this frame is a direct expression of his lifelong dedication to steel and ride quality.

A true modern classic, the Road Logic Signature Edition uses a heat-treated and triple-butted Ritchey Logic tubeset that was designed by Tom, and it features aggressively short-butted sections optimized for TIG welding that save weight and improve ride quality. Ritchey’s proprietary forged-and-machined integrated head tube uses standard drop-in bearings and saves 80 grams over a standard head tube design.

Wrapped in Ritchey Classic Red paint, the Road Logic Signature Edition also features a Ritchey Carbon Fork and spacing for up to 30c tires to deliver a lifetime of enjoyable pedal turns.
