e*thirteen rims are ETRTO compliant and feature hookless flanges which have been tuned over the past decade to deliver “set and forget” tubeless performance, excellent tire retention, and resilience to damage from impacts. 

The compliance engineered into Grappler Flux rims does not affect tire fit or retention. Quite the opposite. With the rim and tire working together, traction is increased, and tire retention is maximized. 

The 30mm inner width of Grappler Flux rims are best suited for 2.3”-2.6” tires, optimizing tire profiles for traction and speed, and allowing for a wide range of tire pressures. While they are compatible with tires slightly wider or narrower than this, there may be compromises to tire stability or profile.
