Without an exorbitant price, the "S" model of the 303 XPLR series represents an effective upgrade for all gravel athletes. These fast wheels incorporate many of the key innovations from ZIPP's premium models for gravel use, without compromising durability. To meet high-performance demands, the design philosophy known as "Total System Efficiency" comes into play, which ZIPP has adapted in this case to address the challenges of gravel riding. The characteristic rim width of the series, combined with tires perfectly tailored to the 303 XPLR wheels, not only reduces air resistance but also minimizes vibrations caused by uneven terrain that act as a barrier, ultimately slowing the rider. Another advantage of the wider rim profile is the increased air volume, which makes it possible to ride with lower tire pressures without sacrificing stability. This also means that the necessary grip for cornering is maintained and that sufficient traction is available for tackling steep climbs. Another benefit of the well-designed rim profile is the seamless transition to the tires, essential for even more efficient aerodynamics. And despite the larger dimensions, the 303 XPLR S wheels remain light enough to allow the rider to recover quickly.
