If you are racing bikes, it is not a question of if you will crash but a matter of when and how hard.
Anyone that has been in a bunch sprint knows that it is a very physical sport and although it is classified as non-contact, you know that it is anything but, especially when that contact is with the tarmac.
Hold your line, hold your position and sprint like hell and while saying a very fervent prayer that when you cross the finish line you cross it first and with rubber side down and that everyone else crosses safely too.
