Unluckiest rider was definitely Leon van Bon. When the group Boonen, Flecha, Hincapie, Backstedt, a.o. was formed he was there but a puncture threw him back to the group Wesemann. And given work he did in that group and the simple way he sprinted to sixth place he definitely had the form to do well had he been in front until Roubaix.
BTW, what did I see: did Michaelsen realy finish in Roubaix with high profile carbon Zipp wheels???
