HollowGram 64
Our R-64 wheels are the product of a singular focus: to produce the highest sustained speeds possible. Aerodynamic drag is minimized, efficiency is maximized, and the result is stable, relentless pace.
HollowGram 50
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.
HollowGram 45
For those who aspire to go higher, the HollowGram R-45 wheels are the way. Precision carbon engineering leads to one of the lightest and toughest rims on the road, and our DRAFT approach creates category-beating aerodynamics. It’s a win-win situation, all the way up.
