"The fastest wheels in the world"

To decrease the weight without taking away the hook, Roval explains that the Specialized Science Club – its cadre of elite engineers – rethought the rims’ layups and developed a process that, through testing varying resin systems and carbon grades, resulted in saving 40 grams per rim. According to Roval: “The team hit industry durability targets after only 10 layup iterations, but that’s not good enough for the Science Club. After 47 additional iterations, we reached our internal, industry-doubling durability standards, resulting in a wheel that helps retain the tire under extreme impact, allowing for safe stopping.” The CLX II Team, like the standard version, has a front rim depth of 51 mm and rear of 60 mm, with internal rim widths of 21 mm for both. The front rim has a wider external rim width than the rear – 35 mm compared to 30.7 mm.

For this new version, Specialized offers this wheelset in a limited edition, totaling 1500 sets worldwide, with a different construction method from the CLX II wheels. They are made in the same factory, but using the "best craftspeople" available, with different resin, smaller layup overlaps, and a redesigned hub.
