Aero Road



Flat-out speed.

Our deepest section rim provides the perfect balance between wind-slicing aero, speed, handling, and strength. This is our road race and criterium weapon of choice. Stiffness and speed like nothing else.

Combining a generous 46mm depth with alternating spoke hole offsets and optimized drilling angles, the GRD-46 rim was thoughtfully designed with intent. It utilizes our composite spoke-and-hub system, combining our ETI hubs and G1 spokes, to provide you with our fastest and most efficient wheel system.
