Hollowgram 50 R-SL Carbon Disc Wheel Set

THE HOLLOWGRAM R-SL 50 WHEELSET

The 50mm rim depth of our R-50 wheels means all-around versatility: low weight, high strength, responsive handling, excellent crosswind stability, and superb aerodynamics that deliver major pace with less effort, wherever your ride takes you.

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.

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.

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.

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.

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
• HollowGram hubs feature a small cross-section and sealed cartridge bearings keeping it light and aerodynamic
• 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

One of the fastest all-round race wheelsets in the world. Developed w/ the new SuperSix EVO and shaped by Cannondale's Draft Aero Design philosophy, the Hollowgram R-SL 50's feature a 50mm deep, super low drag rim, bladed spokes, and DT Swiss 240 EXP internals. It adds up to the perfect wheel for for the EVO's mission... Hitting escape velocity on any road!
