R-SL 64 100x12mm Front Wheel
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
- HollowGram hubs feature a small cross-section and sealed cartridge bearings keeping it light and aerodynamic
- At 1630g a pair the R-SL 64 is impressively stable, in a lightweight package
- A limited lifetime warranty to give you peace of mind
- 100x12 thru-axle compatible
Aero for All
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.
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.
