Some memories there, I sued to race my one of them. Still have my Team Jersey and the Muddy Fox wheel discs, which looked the part - just was more of a hindrance -especially in the wind! The roller cam brakes were quiet powerful at first, but prone to clogging up with Mud and never warmed to the elliptical cracks - although they seemed to be sold as 'ground breaking' at the time. From an era when Muddy Fox made decent bikes.
