Just picked up the newest Dirt and its got an interview with Redraven, a company out of the UK that makes a 230mm rotor and "Alpine brake kit". In another magazine was a picture of a proto Hayes that looks a lot like the Gustav caliper on a 230mm rotor. If people are looking for bigger and better brakes...why not just bring back that dual rotor Shimano prototype they had before they put out the very first XT. I remember reading somewhere that those things had so much stopping power that you'd have to spill brake fluid on them just so that you'd get some modulation.
