If there's any corrosion on the shaft of that shock it's dead, and a lot to repair (has to be sent to the states). If the frame is any size but a small, it's possible to make a conical adaptor and fit an alternative shock, but it's almost as much work as just buying a risse/noleen replacement.
cheers for the heads up ive just had an adaptor made for my other. so if the shock is no good will put the fox float on for now.
was gonna have a few adaptors made but like you say not that cheap lol all in all for adaptor and shock 85gbp so spose better than buying a new noleen.anyone know if the rides better at all ?
