Optimized Rim for Dirt Jumping
The Chaos rim has been specially developed with a 22.5mm internal and 28mm external width. Halo found this to be ideal for Dirt Jump wheels. It allows tires between 2″ to 2.5″ to seat optimally to the rim, which is the most common choice for Dirt Jumping.
Due to priority of reducing rolling resistance and lack of turning corners, dirt jumpers run higher pressures which do not require a wider rim for optimal sidewall interaction. Therefore, it made sense to keep the rim narrower and save on weight. Wider rims result in a greater weight penalty.
The Chaos found the right balance between weight and strength for Dirt Jumping
