Trail, Gman and Rocket -
So Vittoria had given the new Corsa TLR 2.0 to teams a few months back, and honestly, theses things are a bit like magic.. super low Crr and really beautiful ride quality. A couple of the teams put them into racing straight away and have had some great results. A couple of big races have already been won this year on this tire and there is a real sort of magic reputation that the tire has taken on with riders and some of the staff.
Problem of course being that while the overall race speeds have only gone up a few km/hr over the last 20 years, the speed over the pave sectors, particularly Arenberg have risen dramatically. It is common for teams to essentially do a leadout for their key riders onto the harder/narrower sectors, so Arenberg for instance is seeing speeds 5-10kph faster than 20 years ago. This puts way more stress on the tires and wheels and leaves way less margin for error when the tire impacts the cobble edge.
For example the extra 5mm or so or distance between the rim edge and road surface of riding a 30mm rather than a 25mm equates to a ~70% increase in the energy required to bottom the tire against the rim.. so there are some non-linearities in play here that can really bite you in the ass if you aren't accounting for them up front in the math..
So yes, his punctures were pinch-flat / tire damage type punctures caused by riding a tire that was just way too small for these speeds. They could have offset some of this with considerably higher pressures, but of course that presents it's own different problems.
Also, for Rocket_Racing, you can easily pinch flat tubulars here as well.. we saw quite a lot of that in the early days of trying to develop carbon rims for Roubaix.. we could make rims that were more or less unbreakable, but then the failure just transferred to the tire, which made it abundantly clear to everybody that the solution just had to be larger tires.
