The Traverse HD i9 delivers unbeatable control and pinch-flat resistance in severe terrain, unlocking progression in the bike park, on a trail ride, or on a World Cup downhill track.
This is the strongest carbon wheelset in the known universe. The strongest rim shape, combined with off-set spoke drilling and molded with optimized carbon fiber for front and rear-specific characteristics, adds up to the strongest carbon trail wheels Specialized has ever made. The front layup delivers a smooth, control-enhancing ride, while the rear optimizes stiffness and impact strength. The fusion of control and durability, where stiffness meets grip, glues you to your line and snaps you to the next with precision and speed.
The U.S. patent pending flat top bead profile requires 85% more force to pinch flat compared to a standard round bead, virtually eliminating "snake bites." The Roval Threadbed Valve, invented by Chuck Teixeira, threads directly into the rim. This ingenious design eliminates compression nuts and air loss from rim flex, makes tire set-up easier, and reduces sealant clogs.
The i9 1/1 hub optimizes control via a dual-phased-pawl drive mechanism, accomplishing 90 points of engagement and 4 engagement by way of a six-pawl driver and 45-tooth drivering. The result is immediate power transfer from the pedals to the drivetrain, propelling riders forward with minimum lag, perfect for ratcheting through techy sections.
