      Overview

      Aero for All

      The most aerodynamic wheelset we’ve ever engineered, the R-64s are made for endless miles of cheating the wind.

      Highlights

      • Developed with D.R.A.F.T. our 64mm deep, 21mm internal/32mm external width carbon rims are incredibly aerodynamic and tubeless compatible
      • We optimized DT Swiss Aerolite spokes with a 2:1 lacing pattern, giving an highly balanced aerodynamic wheel
      • Built with ultra-reliable HollowGram hubs and premium DT Swiss 240 EXP rear internals for performance and ease of service with our custom straight pull hub shell
      • At 1630g a pair the R-SL 64 is impressively stable, in a lightweight package
      • Shimano freehub body compatible

      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.

      SL: No Compromises

      HollowGram SL wheels rise to even higher speeds. DT Swiss Aerolite spokes – shaped for lower drag without losing strength – are paired with custom HollowGram hub shells. Ultra-reliable DT Swiss 240 EXP internals at the rear bring a 36-tooth freehub ratchet for instantaneous pedaling engagement while minimizing mechanical drag. In HollowGram speak, SL means weight is lowered, responsiveness is increased, and aerodynamic efficiency is maximized.

      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.
