For this wheelset, we started with rims made to our specifications by one of the leading manufacturers of high-quality carbon rims in the world, who also produces rims for several larger brands.

The 50mm deep full carbon rims have an outer width of 25mm, an ovalized U-shaped profile for increased rigidity and aerodynamics and simple, understated black on black branding.

Laced to low flange Gran Compe SF track hubs using Sapim Race double butted spokes and Polyax brass nipples, we built these wheels to be a perfect mix of strength, durability and light weight in order to ensure they will be just as reliable on the street as they are velodrome-worthy.

Hand built at Retrogression in Portland, OR.
