Wide, robust and proven, the Zipp 303 XPLR SW has been rolling on gravel since 2024, making it the oldest wheelset in the test field. Age hasnt blunted its appeal: extra-wide hookless rims, conventional steel spokes and a warranty that extends to riding damage give it a solid foundation. The question is whether that proven recipe can still hold its own against the best in our big gravel wheel group test.This wheelset was tested as part of our big 2026 gravel wheel group test you can find an overview of all the wheels on test here.Zipp 303 XPLR SW | 1,424 g | 1,800 | Manufacturer websiteFew wheel brands carry as much weight as Zipp, so its presence in this group test comes as no surprise. The Indiana-based SRAM subsidiary moved early on gravel with its XPLR range, adding the 303 XPLR SW and its exceptionally wide rims in August 2024. Where others have chased low weight or turned to carbon spokes, Zipp has stuck to width, durability and a comprehensive warranty. With a wave of newer competitors lining up against it, the American brand has to show that its approach still stands up two years later.The Old Hand The Zipp Carbon Gravel Wheelset in DetailZipp has clearly prioritized width over weight, and the rims leave no room for doubt. An internal width of 32 mm and an external width of 40 mm put them among the widest in the test, while a 54 mm rim depth front and rear gives them a purposeful profile. On our scales, the wheelset weighs 1,424 g, a mid-pack figure, yet it feels a touch heavier on the road than the number suggests. The extra width also changes the shape of the tire: our 45 mm Continental Competition control tire swells to 48.0 mm at the front and 47.8 mm at the rear. That sits securely on the hookless, TSS-compliant rims, but the broader profile blunts the tires responsiveness slightly. Zipp approves the rims for tires from 40 to 61 mm and pressures of up to 3.45 bar.Going wide With a 32 mm internal rim width, the 45 mm Continental Competition tyre grows to 48 mm.Straight side The TSS-standard hookless rim is approved for pressures of up to just 3.45 bar.Golf ball The familiar dimple pattern from previous Zipp wheels also makes an appearance on the 303 XPLR SW.The spokes are a deliberate nod to tradition. Each wheel runs 24 conventional J-bend steel spokes with external nipples, which means replacements can be sourced and fitted at virtually any bike shop, a real advantage if something breaks far from home. Theyre laced to ZR1 hubs offering 66 points of engagement and stainless steel bearings, with a freehub that sounds crisp and high-pitched without drawing attention to itself. The look is understated, though the combination of conventional spokes and this rim profile is beginning to show its age. At 1,800, the Zipp wheelset is among the more affordable in the test, and the lifetime warranty for the original owner, which covers even damage sustained while riding, adds considerable value.66 points of engagement The ZR1 hub engages quickly and makes a crisp, high-pitched buzz without ever getting annoying.J-Bend Conventional spokes with external nipples should be easy to find in any bike workshop.Keeping Calm The Zipp 303 XPLR SW on TestOn our test route, the Zipp wheelset proved to be composed, stable and reassuring, making you feel at home on just about any kind of gravel. Off the line, however, its in no particular hurry to get going, falling slightly below average in this highly competitive field. The wheelset is stiff enough to keep the steering predictable and stable, though it stops short of the lively, direct feel the stiffest wheels in the test deliver.Despite its wide rims, the Zipp wheelset finishes mid-pack for comfort, with the rims and overall construction offering relatively little compliance. On the trail, it performs well but feels somewhat harsh, holding its line rather than darting from corner to corner. That stable, unflustered handling inspires confidence on easier trails, although more demanding terrain and long stretches of tarmac arent its forte. The wheelset is capable of racing, but its at its best on long days in the saddle, when confidence and stability matter more than shaving off the last few seconds.Older, But Slower? The Zipp 303 XPLR SW in the Wind TunnelOut on the road, the Zipp wheelset impresses above all with its stability and reassuring handling. But can the oldest wheelset in the test still keep pace with the latest generation on aerodynamics? Based on feel alone, youd be forgiven for thinking not. The wheelset rolls well but never feels especially efficient, likely due in part to its weight and moderate stiffness. The wind tunnel tells a more encouraging story. With a rider on board at 36 km/h, the Zipp requires 1.5 W less than our reference wheelset, the DT Swiss GRC 1100, which translates into an 11.0-second advantage over 40 km. Its a modest gain, but it shows the Zipp is far from outdated aerodynamically. Its sluggish acceleration may explain the gap between perception and reality: a wheelset thats slow to get up to speed can feel less efficient even once youre cruising, whatever the numbers say.Conclusions about the Zipp 303 XPLR SWThe Zipp 303 XPLR SW is the seasoned veteran of our test field, delivering composed, predictable and confidence-inspiring handling on a wide range of gravel surfaces. The wind tunnel confirms that its aerodynamics remain fully competitive. The latest generation has the edge on acceleration, responsiveness and comfort, and the Zipps looks are starting to show their age. Even so, for long days on gravel, it offers a dependable, hassle-free package at 1,800, and a lifetime warranty that even covers riding damage makes it one of the safest investments in the test.TopsComposed and confidence-inspiring on all kinds of gravelBetter aerodynamic performance than the ride feel suggestsWide rims accommodating a broad range of tyre widthsLifetime warranty, including damage sustained while ridingFlopsSlightly sluggish accelerationHarsh ride on rough trailsMore information at zipp.com.The Test FieldThis wheelset was tested as part of our big 2026 gravel wheel group test you can find an overview of all the wheels on test here.All wheels on test: CADEX Max GXR | DT Swiss GRC 1100 DICUT 50 | ENVE G SES 6.7 Pro | Fulcrum Sharq GR | HUNT 5AM Gravel Limitless Ti_UD | Leeze CH 60 PRO GX | Light Bicycle AG48 | NEWMEN Streem G.62 CS | OQUO RP50LTD CS | Reserve 48|53 GR | Roval Terra Aero CLX | Vision SC 45 i30 | Zipp 303 XPLR SWDer Beitrag Zipp 303 XPLR SW Gravel Wheelset on Test erschien zuerst auf GRAN FONDO Cycling Magazine.
