They use one or more brake stiffeners to improve the stopping power of the Vs, but the only disc brakes they use are on the front.
I only use one Rear brake on my bike, although its a very good one i have a Hope mono M4, will probably get a front brake at somepoint though...
Also, why would a disc brake snap the frame? The frame on Dirt jump rigs are Soid as a rock, and are built for hard hits, why would a dick brake, which are featured on XC bikes now and they're less strong as they're built to be lightweight, i dont understand how using a disc brake on the back will snap the frame..
the only way that i can imagine that working, is by slamming your brakes on seriously hard and quickly the put a huge stress on the frame, and usually you dont need to do that for dirt jumping, and even if you did, i still cant see the force of braking being strong enough to snap the frame...
