RON'S BIKES Aluminus Maximus Frame Set｜A "NEO-VINTAGE" Gravel Racer Designed by ULTRAROMANCE

Not simply nostalgic for the old, but reinterpreting it anew.

The "Aluminus Maximus" is RON'S BIKES' first original frame. It is a special gravel frame designed by Ronnie Romance, also known as ULTRAROMANCE, a vital figure in US bike culture, who brought his own ideals to life.

Drawing inspiration from numerous legendary bikes such as the Charlie Cunningham, Specialized Crux, OPEN U.P., and MOG, it achieves a unique presence that belongs to no other. Manufactured by the New England master craftsman "Frank the Welder" in the USA, it is handcrafted from aerospace-grade 7000 series aluminum.

The unpainted aluminum frame deliberately retains beautiful TIG weld beads, merging a classic feel with modern performance. Strong attention to detail is evident throughout, such as the brake system specifically designed for PAUL Racer Braze-on, and the shaping around the rear brake which doubles as a booster.

With a 700c-specific design that accommodates up to 47c tires, it supports a wide range of uses, from speedy gravel rides to long tours. It is a one-of-a-kind frameset that possesses modern performance while evoking a sense of nostalgia.
