The balanced profile, rim width and gravel-optimized hubs ensure explosive power transfer on any surface and transform rough roads into smooth sailing.\u003c\/p\u003e\n\u003cp\u003eIntegral Design, Rides Light and Fast\u003cbr\u003eInstead of being a combination of components and sub-assemblies, EXAR carbon fiber wheelsets are quality and high-performing products featuring an integral design of appearance, weight, and performance.\u003cbr\u003eGR45 Pro applies HI-MOD carbon fiber on rim. While the rim, spoke and hub remain stiff, we optimized materials and structure to keep it as light as possible. The light design effectively reduces driving weight and improves sprinting performance.\u003c\/p\u003e\n\u003cp\u003e*The wheelset weight doesn’t include the weight of quick-release skewer and rim tape. A tolerance of ±3% applies to the weight, and the actual wheelset weight should prevail.\u003c\/p\u003e\n\u003cp\u003e45mm Aero Profile, Balanced Rigidity for All-terrain Domination\u003cbr\u003eCompared with lower-profile wheels, the 45mm rim depth reduces frontal wind resistance, delivering significant aero gains. At the same time, it achieves the perfect balance of torsional and lateral stiffness, ensuring uncompromising power transfer under high-torque efforts.\u003c\/p\u003e\n\u003cp\u003eWhere aerodynamics meets unwavering rigidity, the GR45 Pro unlocks peak performance across every terrain.\u003c\/p\u003e\n\u003cp\u003e32mm Fat Rim, Ultimate Comfort\u003cbr\u003eEngineered for gravel bikes, the 32mm external \/ 25mm internal width wide rim delivers superior aerodynamics in turbulent crosswinds while enhancing stability.\u003c\/p\u003e\n\u003cp\u003eWhen paired with 35c and above wide tires, the wider rim provides enhanced tire support, reducing deformation to improve cornering grip and steering precision. Meanwhile, it enables lower tire pressure, significantly boosting comfort on rough terrain by absorbing vibrations more effectively. This scientifically optimized combination achieves the perfect balance between tire stability, handling control, ride comfort, and aerodynamic efficiency.\u003c\/p\u003e\n\u003cp\u003eTubeless-Ready, Tape-Free\u003cbr\u003eCompatible with both tubeless and clincher tires. Without spoke holes, the rim is tubeless-ready with no need of rim tape.\u003c\/p\u003e\n\u003cp\u003eElaborate Hub Design, Engineered for Gravel\u003cbr\u003eFront Hub: Features a 24-hole, 1:1 lacing pattern with crossed spokes on both sides for enhanced durability. This design engages more spokes under braking for enhanced stability and power distribution. It effectively disperses impact forces on rough terrain and delivers smoother braking performance.\u003c\/p\u003e\n\u003cp\u003eOptimized Flange Spacing: The front hub’s wider flange spacing improves spoke bracing angles and tension distribution, maximizing lateral stiffness and support.\u003c\/p\u003e\n\u003cp\u003eRear Hub: Utilizes a 24-hole, 2:1 lacing configuration to reinforce drive-side efficiency while maintaining critical lateral rigidity.\u003c\/p\u003e\n\u003cp\u003eMore Powerful Design\u003cbr\u003e36-tooth flat ratchet offers greater engagement force, durability, and stability, with smoother, consistent sound. It supports quick swaps for different tooth counts, adding versatility.\u003c\/p\u003e\n\u003cp\u003eGR45 Pro features Pillar Wing20 steel spokes. Compared with carbon spokes, steel spokes have superior vibration absorption, impact resistance, and durability while on rugged gravel terrain.\u003c\/p\u003e\n\u003cp\u003eGR45 Pro wheelset is UCI approved, meeting the strict performance and safety standards of professional racing—so you get lab-tested reliability that thrives in real-world gravel chaos.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSpecifications\u003c\/strong\u003e\u003cbr\u003eModel    GR45 Pro\u003cbr\u003eBrake    Disc brake\u003cbr\u003eHeight    45mm\u003cbr\u003eWeight    1490g (Include ±3% tolerance on weight,Without rim tape and valve)\u003cbr\u003eExternal Rim Width    32mm\u003cbr\u003eInternal Rim Width    25mm\u003cbr\u003eRim Material    HI-MOD carbon fiber\u003cbr\u003eSpoke    Pillar Wing 20\u003cbr\u003eFront Wheel Spoke Tension    brake side 110kgf±10%\u003cbr\u003eRear Wheel Spoke Tension    drive side 130kgf±10%\u003cbr\u003eFront Wheel Spoke Lacing    24H 1:1\u003cbr\u003eRear Wheel Spoke Lacing    24H 2:1\u003cbr\u003eRatchet    36T (Replaceable ratchet with different tooth amount）\u003cbr\u003eFrame Spacing    100\/142mm thru-axle\u003cbr\u003eFreehub \u003cmeta charset=\"utf-8\"\u003e\u003cstrong\u003eSram XDR freehub \u003c\/strong\u003e(Campagnolo N3W and \u003cmeta charset=\"utf-8\"\u003eStandard Shimano 11-speed are available separately).\u003cbr\u003eCompatible Tire Type    Clincher tire, tubeless tire\u003cbr\u003eCompatible Tire Width    Compatible with 28c tire and above\u003cbr\u003eMaximum Tire Pressure    Clincher tire 120psi，Tubeless tire 110psi\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIn the box\u003c\/strong\u003e\u003cbr\u003eCarbon fiber front wheel*1\u003cbr\u003eCarbon fiber rear wheel*1\u003cbr\u003eTubeless tire valve*2\u003cbr\u003eManual*1\u003c\/p\u003e","brand":"Magene","offers":[{"title":"Wheelset - SRAM XDR","offer_id":51377456349400,"sku":"GR45-PRO","price":1499.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2348\/1571\/files\/magene-exar-gr45-pro-wheelset.png?v=1770683787","url":"https:\/\/ccache.cc\/zh\/products\/magene-exar-gr45-pro-wheelset","provider":"CCACHE","version":"1.0","type":"link"}
