SMOOTHER IS FASTER: Trail riders who prize nimble handling will be blown away by the category-leading control strength-to-weight ratio and pinch-flat resistance of Traverse SL II i9. STRONGER: Front and rear-specific rims with carbon layups optimized for strength and weight boast 15% greater front wheel strength and 25% more rear wheel strength than the previous Traverse SL. VERTICAL COMPLIANCE: The new Traverse SL II i9 1/1 is 21% more vertically compliant than the previous model delivered through a shallow rim shape and front/rear-specific layup which enables enhanced terrain-hugging and bump-force-absorbing control. TRACTION MONSTER: Carefully engineered rim shape intentionally flexes for improved support and traction to boost confidence and control. TOUGH LIFE LONG LIFE: Engineered rim offset enables balanced spoke tension for improved fatigue life. SAYONARA PINCH FLATS: Our 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.” AIR TIME: Thank our genius engineer Chuck Teixeira for inventing the “Roval ThreadBed Valve”—a valve that threads directly into the rim. This ingenious design eliminates compression nuts air loss from rim flex makes tire set-up easier and reduces sealant clogs. HIGH ENGAGEMENT: 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.
