The Giro, le Tour, and the current Vuelta have all been marred this year by nasty crashes. Now, there have always been crashes in cycling, and always will be, but they just seem to be increasing in number from previous years and I am wondering why. Is it the bikes? The frames always look too small to me and very twitchy, or is it simply that the races are now being ridden at much higher speeds than they were. I would be interested what people think, even if there are no more crashes than normal and it is all in my imagination!
