If the MBS Pros have inspired you to test your skills on some rails you're going to want a set of MBS Matrix III Cross Lockers. Why? Mountainboard trucks are much wider than skateboard trucks and the rubber tires are grippier than skateboard wheels. This makes balancing on rails (and sliding once you're on) a real challenge. MBS Cross Lockers allow you to diagonally lock your trucks onto rails the same way skaters do, locking you into your grind with stability and confidence. Simply slide them onto your hangers and adjust to your preferred width. Note: Only compatible with Matrix III trucks.
