Cannondale R-S 64 700c Hollowgram Front Road Wheel – 100x12mm – Black

The most aerodynamic wheelset we’ve ever engineered, the R-64s are made for endless miles of cheating the wind.

Aero Hero:
All HollowGram road wheels punch above their weight class in aerodynamic performance, but the R-64 wheelset punches the hardest. Its incredibly low drag coefficient rivals that of deeper wheels, slicing the wind and carrying speed better than the competition.

Light Speed:
Rising to speed isn’t just about blistering pace. It’s about responsiveness and agility, too. The R-64 rim is specifically engineered to balance aerodynamics with low weight and sharp handling, helping you carve up the corners as well as the flats.

Keeping Up:
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.

Key Features:

• Developed with D.R.A.F.T. our 64mm deep, 21mm internal/32mm external width carbon rims are incredibly aerodynamic and tubeless compatible
• Grand Forza double-butted spokes keep it light while staying strong and reliable
• HollowGram hubs feature a small cross-section and sealed cartridge bearings keeping it light and aerodynamic
• At 1730g a pair the R-S 64 is impressively stable and reliable
