The Mozo air sprung suspension provides 100 mm of suspension travel to help soften the ride and provide better performance off road. The fork features a lockout lever to allow quick adjustments during a ride to stiffen or soften your fork, while more fine tuning can be performed by using the air adjustment valve with a high pressure shock pump to dial in the performance for your weight and riding style.

Featuring a wire bead, 60 TPI construction and durable treads, these tires are among the best tires available in the fat tire category.
