So, I'm coming down this hill near the end of my 55 miler today. I'm tucked in, doing about 30 mph but starting to brake as the traffic ahead is slowing for the lights at the bottom. All of a sudden I hear a 'pop' and straight after my stem mounted Edge 705 departs for the tarmac. I feared the worst as it not only had to contend with hitting the tarmac but there was also a stream of traffic following as well. As soon as I pulled over I could see it lying forlornly in the offside tyre path of the descending vehicles. The first two drivers luckily saw it and drove round and I managed to wave the third driver to a halt so I could retrieve it. Thanks guys. The damage? Well, apart from a scuff on one corner all seems well. It carried on recording and i have been able to download the days ride without any problem. Both cable ties had failed and I can't for the life of me see why they did so at this particular point. There was no jarring, unusual vibration or sudden bumps and sabotage is highly doubtful. I'll make sure I feed the thickest two cable ties I can into the mount when I remount it tonight. A lucky escape me thinks! Anyone else had anything similar?
