Ok my new speedo cable arrived to day and when I was fitting it I found out the mount could be swung back up to protect the cable by simply loosening a lock nut. I know hindsight is 20/20 vision, when the super singles were fitted, the fitter must have turned the angle down to fit the speedo adjustment unit (which we do not use anymore). The cable is now sitting quite close to the running gear and much safer.
