Crafted from welded 6061 aluminum for exceptional durability.The RACE FACE ARC 30 Offset rim is the definitive choice for riders seeking a robust, reliable, and high-performance foundation for their custom wheel build. At the heart of its design is the asymmetrical, offset nipple bed. This crucial feature allows for more even spoke tension between the drive-side and non-drive-side of the wheel, creating a significantly stronger, stiffer, and more durable wheel structure. The result is a wheel that tracks more accurately through rough terrain, responds instantly to rider input, and maintains its integrity through seasons of aggressive riding.Designed with modern mountain biking in mind, the generous 30mm internal width provides an ideal platform for today´s wider trail and enduro tires. This optimal tire profile enhances grip, improves cornering stability, and allows you to run lower tire pressures for a smoother ride and maximum traction on loose or technical climbs. The tubeless-ready design features a secure bead lock that firmly holds the tire in place, preventing burping and ensuring a dependable seal, even under the most aggressive cornering forces.Durability is paramount, and the ARC 30 delivers. Constructed from high-grade 6061 aluminum with a welded seam, it offers superior strength and impact resistance compared to pinned-joint alternatives. This construction not only bolsters the rim´s overall resilience but also creates a perfect, airtight seal for hassle-free tubeless setup. For those pushing the limits in bike parks or on downhill tracks, the available Heavy Duty (HD) version is built to withstand the most extreme forces, giving you the confidence to send it bigger and ride faster.Whether you´re upgrading your current setup or building your dream bike from the ground up, the RACE FACE ARC 30 Offset rim provides the perfect blend of modern design, strength, and trail-proven performance.Technical Specifications* Material: Welded 6061 Aluminum* Attributes: MTB Cycling, Rims* Internal Rim Width: 30mm* Spoke Hole Offset: 4.5mm* Tubeless System: Tubeless Ready with secure tire retention bead* Available Diameters: 27.5, 29* Available Spoke Counts: 28h, 32h* 27.5: 554mm * 29: 592mm* Finish: Black Anodized with high-durability Vinyl Decals. tradeinn Bikeinn
