Last night, we saw what was probably the greatest surprise in the modern history of sport; I don't think any other winners have come close to the 5000-1 odds offered on Leicester to win before the season started. So what do people think was the biggest surprise in the history of cycling? Obviously, a lot of this is inevitably tied up with clinic stuff, but I'd still be interested to see what people consider to be the biggest surprises in cycling's long history. Hayman's Roubaix is surely the most surprising monument win of the past decade; what about previous eras and other races?
