Industry Nine Deal Classic Hydra2 Wheels World Cup Tech, Serviceable Setup DH riders on older non-Boost frames finally have a wheel that gives them Hydra2 engagement without requiring a new bike. The Deal carbon rim was developed alongside We Are One using hookless construction specifically tuned for hard-charging descents - reinforced materials and a refined laminate built to absorb heavy compressions and big-speed impacts without giving up sensitivity. Pair that with the Hydra2 hub's 870-point phased-pawl engagement on a conventional flanged hubshell running j-bend steel spokes, and you get a wheel that's fast off the line, easy to service trail-side, and engineered to take a beating all season.
