Origin

The R1 Disc is Radon's aluminum road platform — designed to bring disc brakes and modern stiffness to riders who want road performance without paying for a carbon frame. A full carbon fork keeps the front end light and compliant despite the aluminum main frame. Offered across a broad groupset range from Shimano Tiagra to SRAM Rival eTap AXS wireless, the R1 covers entry-level to enthusiast price points with the same core platform.
