Unlike typical gravel wheels, which are adapted road wheels prioritizing stiffness and weight, Zipp’s design centers exclusively on speed. Recognizing that rolling resistance, vibration from uneven terrain, and wind significantly reduce gravel speed, Zipp applied its Total System Efficiency philosophy tailored to these challenges. The 303 XPLR SW is a purpose-built gravel wheel, designed around the ideal gravel tire for maximum performance.\u003c\/p\u003e\n\u003cp\u003e To develop this first-of-its-kind wheelset, Zipp engineers learned from studying how gravel racing has changed cycling in recent years, coming to several vital conclusions:\u003c\/p\u003e\n\u003cp\u003e1. The progression of gravel speeds increases the importance of aerodynamic efficiency.\u003c\/p\u003e\n\u003cp\u003e2. Current generation gravel wheels exhibit poor aerodynamic efficiency with gravel tires.\u003c\/p\u003e\n\u003cp\u003e 3. Low tire pressures are the key for unlocking speed on gravel, but current gravel rim design provides insufficient tire stance to support lateral cornering loads at lower tire pressures.\u003c\/p\u003e\n\u003cp\u003e4. Current gravel rim designs do not help prevent pinch flats while using lower tire pressures.\u003c\/p\u003e\n\u003cp\u003eGravel racing tires typically range from 38 to 50mm in width with diverse tread patterns, while most gravel wheels feature a narrower external rim width of 28-30mm. This mismatch causes the tire to bulge outward rather than form a smooth, aerodynamic profile. Zipp’s 303 XPLR SW wheelset addresses this by pairing a wide rim with gravel tires, delivering a 5-watt aerodynamic gain over top competitors. Designed for use with Goodyear XPLR Slick and Inter tires, the wide tire bed supports lower pressures without tire collapse during cornering, enhancing control and traction. Its rim edge is 77% thicker to reduce pinch flats, and the 54mm rim depth optimizes aerodynamics at race speeds above 35kph, perfectly matching the tire’s profile for efficient performance.\u003c\/p\u003e\n\u003ch5\u003eKEY FEATURES\u003c\/h5\u003e\n\u003cul\u003e\n\u003cli\u003eFastest race wheel on gravel,features tubeless and hookless rim profile\u003c\/li\u003e\n\u003cli\u003eUltra-wide internal profile for decreased rolling resistance, ability to run pressures under30psi (2.1 bars)\u003c\/li\u003e\n\u003cli\u003eWide and deep profile integrates seamlessly with gravel tires to increase aerodynamic efficiency \u003c\/li\u003e\n\u003cli\u003eApplies Zipp’s Total System efficiency to high performance gravel \u003c\/li\u003e\n\u003cli\u003eMax tire pressure 50 psi\/3.45 bar -ZR1 DB hub is engineered in Germany with better seal design for improved durability and quicker response with 66points of engagement \u003c\/li\u003e\n\u003cli\u003eCenter locking rotor interface.
