We took the same competition-ready design of our full-size Crown Gem and developed smaller versions for junior mountain bike competition. Available in sizes from 12 to 24 inches, this tire offers tubeless options in 20 and 24 inches to deliver true off-road performance, no matter your size, while maintaining a highly competitive weight. Its unique tread pattern features specially designed side knobs for cornering control and an aggressive center knob for added traction and speed.
