The Chamber Pro II is a rugged six-spoke true beadlock wheel cast from A356-T6 aluminum. It features an inner bead reinforcement that substantially strengthens the wheel. Its dual valve stem setup allows the owner to monitor air pressure out on the trail while airing up or airing down.
The beadlock ring is manufactured from 3/4-inch billet 6061 T-6 aluminum and the underside features a vertical ribbing that helps keep the tire from slipping under extreme conditions.
Each of the beadlock holes has a mounting insert to provide easy thread replacement if any of the threads become damaged. The ring is attached to the wheel using Grade 8 zinc-plated 3/8 socket-head hardware that, when mounted, is flush with the ring.
The Chamber Pro II is ATX’s latest evolution of the original Chamber Pro, first made available five years ago. New features for the 2014 reintroduction of this popular wheel enhance its performance and durability.
