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
- 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 1520g a pair the R-SL 50 is the premium blend of lightweight and aerodynamic performance
- A limited lifetime warranty to give you peace of mind
- Shimano freehub body compatible
Aero for All
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.
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.
