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 theyre 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.

The D.R.A.F.T. Approach
Its one thing to cut through the wind. Its 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.
