You never want to be left stranded with your gear, especially not on your adventure tour. At e*thirteen, we know from our experience in mountain bike racing how to create the perfect blend of performance and reliability. We offer a lifetime, hassle-free replacement guarantee on our carbon rims, no questions asked. Sometimes things break, especially when riders push their limits. When those limits are exceeded, mistakes happen. That's why we've designed our carbon rims to still seal tubeless even when they fail. Adventure rides can take a heavy toll on equipment. Unexpected surprises like sticks in the spokes or a bent derailleur hanger sending the chain into the spokes—our aluminum hub axle allows for easy, tool-free maintenance on the trail. A unique, non-losing end cap thread ensures that the cassette and freehub body don't fall into the dirt when the rear wheel is removed. For optimal reliability, redundancy is key. 6-bolt brake rotor interfaces of superior reliability can be easily maintained with a multi-tool.
