Ben it dont matter what bike you ride, its the rider that counts. Anyway carrera banshees are based on kona stinkys, they may be sold in halfords, but ive seen more broken stinkys then carreras
mate, they are ok bikes, but they do break stupidly easily. not always the frames, but the components, because they are cheaply built. being based on another bike doesnt make them better either.
but still, it shouldnt matter where a bike is sold. its still an ok bike.
