Yes. The 25mm internal width of this rim comfortably accommodates gravel tires up to 45mm wide, making it well-suited for gravel endurance and mixed-surface racing. The wider internal channel improves tire casing support and reduces pinch flat risk compared to rims under 21mm internal width.

Switching from the 460g standard to the 385g extreme light grade saves 75g per rim, or approximately 150g per wheelset. At typical road build weights, this is a measurable reduction. However, the extreme light layup has a tighter structural margin; it is best suited for riders under 75 kg on road-only surfaces. What is the difference between 45mm and 50mm depth for climbing vs flat roads? The 45mm depth offers a lower aerodynamic drag penalty in crosswinds and a marginally lower rim weight, making it the preferred choice for climbing and technical courses. The 50mm depth provides greater aerodynamic advantage on flat or rolling terrain above approximately 38 km\/h. For a general-purpose disc brake build, the 45mm depth is the more versatile option. What should I look for in a wide carbon rim for a tubeless disc brake setup? Key parameters include: internal width ≥23mm for road tubeless or ≥25mm for gravel tubeless, a hooked or hookless bead seat profile, flatness tolerance ≤0.2mm for reliable tubeless seating, and a valve hole diameter compatible with your valve stem (6.5mm accommodates most standard road valves).
