I will bet my house on Pozzovivo wearing a helmet when we next see him race.
He would have to complete as the UCI made helmets compulsory after “Andrei Kivilev” crash/death in 2003. There's been deaths since like the high profile death of “Wouter Weylandt”.
It also helps that teams/riders are paid to wear helmets by sponsors and road cycling is a difficult to make money from (it’s free to watch by the side of the road and most cycling races are not on TV).
It’s interesting that a lot of pro stop wearing once there’re stopped paid to.
To throw some paraffin on the debate and change tack on “should you or shouldn’t your wear a helmet”.
The crash showed clearly that road cycling helmets have not face/frontal protection, hence the cut and all of the blood.
The front of your brain (or in fact the rattling about of it) is equally exposed at the front compared to the back and top (the fact you cycle face first probably, more so).
Does this mean the pro-helmet people are going to wearing a helmet with face protection , such as , DH mountain bike, BMX design, as if safety is the concern then you would choose the better design?
