        Aero for All

        Aero Hero
        All HollowGram road wheels punch above their weight class in aerodynamic performance, but the R-64 wheelset punches the hardest. Its incredibly low drag coefficient rivals that of deeper wheels, slicing the wind and carrying speed better than the competition.
        Light Speed
        Rising to speed isn't just about blistering pace. It's about responsiveness and agility, too. The R-64 rim is specifically engineered to balance aerodynamics with low weight and sharp handling, helping you carve up the corners as well as the flats.
        Keeping Up

        High-performance tire technology has evolved, and HollowGram is here for it. Aerodynamic profiles, 21mm internal widths, and hooked sidewalls for tubed or tubeless compatibility are part of every package. When paired with modern road tires, the result achieved is an ideal blend of ride quality, aerodynamic efficiency, and low weight.

        The D.R.A.F.T. Approach

        It’s one thing to cut through the wind. It’s another thing to master it. D.R.A.F.T. stands for Drag-Reducing Aerodynamic Flow Technology, an approach pioneered over the course of thousands of testing hours by our in-house aerodynamicists and applied to all HollowGram road wheels. We leverage data and testing focused on real-world riding conditions – like headwinds, crosswinds, and variable winds that shift as you ride – not just those that are simulated in a wind tunnel. The result is rim properties that work with the wind, not against it, and wheels that help you go faster, not just look faster. D.R.A.F.T. creates wheels that help you Rise to Speed, no matter the day.
