The Traverse Alloy rim geometry is optimized for strength, crafted with durable alloy, and laced to DT 350 hubs with stout Sapim spokes and Sapim alloy nipples. This wheelset hits harder, holds up longer, and is designed to inspire you to go bigger and farther than any other trail wheel. The engineered rim shape emphasizes durability and strength of alloy, creating one of the most durable alloy wheels available. The new 6013 alloy material is finished with shot peening for impact strength and fatigue strength. Engineered rim offset enables balanced spoke tension for improved fatigue life to keep you rolling. Balanced spoke tension results in consistent flex when cornering. The 30mm internal rim width optimizes tire shape for the best traction, and an internally engineered bead shape ensures the bead bends inward for air pressure and tire retention under impact.
