Modern road cycling is constantly evolving and pushing standards aside in the quest for raw speed. By thinking about the wheel and tire as a system, new levels of performance are achieved. The all-new Goodyear Vector R Z30 SW and R Z35 SW are optimized around Zipp’s new 303 Firecrest allowing riders to further push the limits of what’s possible. Vector R Z30 SW and Z35 SW are developed with volume and durability in mind. A short ply construction and sturdy 120 TPI casing perfectly complement the Zipp 303 Firecrest to conquer any road surface, in any conditions. The rolling qualities of the Dynamic: UHP compound will be your ally in the conquest of those challenges.
