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.

    Where do you start? Light weight, responsive and plenty of snap when you lay down the power. These wheels have helped propel my riding to new levels! you will not be disappointed in these wheels…

    Truly love these wheels. I got my set just over a year ago and have put in about 3600 miles on them. They are so much fun to ride a completely transformed my bike right from the start. I really like the depth of the rims balanced with the weight allowing for me to really hammer it on both ups and downs. Would recommend for any riders looking for an upgrade!
