Previous generations of e*thirteen Plus and Race wheels prioritize exceptional strength and durability, making them legendary on the World Cup as the only wheels that perform race after race on the world’s toughest tracks. While these rims provide riders with the confidence they need to push their limits, they are also very stiff, which means a fast and precise wheel, but also one that transmits a lot of trail feedback to the rider. 

e*thirteen took our rim game to the next level by addressing the desires of our pro riders and consumers, to reach the strength and resilience benchmarks set by LG1 and Grappler rims, while increasing compliance. Compliance in wheels increases comfort, reduces rider fatigue, and improves traction and tracking by decreasing wheel deflection. 

Grappler Flux rims and wheels were engineered with Ride Dynamics as a priority. They strike a good balance between durability, the lateral stiffness needed for precise control, and the ideal level of vertical compliance required to create a more comfortable wheel that improves performance. Rebound energy was also tuned to blend the damping quality that takes the sting out of impacts, with a dynamic ride feel that keeps them lively out of compressions. 

Several competitors have also claimed compliance in rims and some have hit the sweet spot. However, no other wheels we have tested can weigh up to e*thirteen Grappler Flux rims for performance-enhancing compliance and strength.

Other common issues with compliant rim designs are excessive flexibleness or the “tire rollover” feeling when rims twist under load, such as pushing into corners. It was paramount for e*thirteen to maintain ride quality in every way with the new Grappler Flux. After multiple seasons of testing on the World Cup, we feel the Grappler Flux ticks all the boxes. The proof is in the ride!
