      Overview

      Aero for All

      Rise to Speed anywhere. The R-50’s brilliance is its breadth of ability. With supernaturally balanced performance, you’ll find your fast on any road.

      Highlights

      • Developed with D.R.A.F.T. our 50mm deep, 21mm internal/32mm external width carbon rims are aerodynamic, lightweight, tubeless compatible
      • Grand Forza double-butted spokes keep it light while staying strong and reliable
      • Built with our custom straight pull HollowGram hub shell and ultra-reliable DT Swiss 350 rear internals for performance and ease of service
      • At 1620g a pair the R-S 50 is a blend of lightweight and aerodynamic performance
      • Shimano freehub body compatible

      Aero for All

      Sweet Spot
      The R-50s achieve superior aerodynamics while weighing 100 grams less than our already-light R-64s. They hit the performance sweet spot between aerodynamic efficiency and lightweight responsiveness.
      Real Reliability
      The R-50s will reliably deliver performance in a variety of conditions, and they’re also just plain reliable. Strong spokes, DT Swiss hub internals, and hand-built precision mean you can go hard on any ride or in any race, season after season.
      Keeping Up

      High-performance tire technology has evolved, and HollowGram is here for it. Tubeless compatibility, 21mm internal widths, and hooked sidewalls are part of every package. It’s all optimized around modern road tires, for that 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.
