i have a lot of miles on that tire, and it’s a great, great tire. i would not hesitate to race that tire in a 70.3 or longer because i hate flats, and that tire doesn’t flat. it’s kind of like the corso pro in that it’s unlikely to flat and pretty fast for a no-flat tire.
n=1, but I have never had more sidewall cuts than in my Pro One era. Doesn’t justify the slightly sub-par Crr for me given the poor puncture resistance.
i think this is a large part of why we get conflicting reports on puncture resistance. i’ve not use the pro one but comparing the corsa pro and gp5k its clear that the difference is in the sidewall - gp5k has tougher sidewalls so more protection there but also why it is often said to have bad “feel”. tread protection on the corsa pro is as good if not better than the gp5k so the practical experience will depend on what sort of hazards your roads contain - smaller stuff that primarily hits the tread or bigger things that stick up into the sidewall.
Yeah slowman’s experience doesn’t seem to match the general trend at all. On the WW forum, many early adopters gave up on Corsa Pro because of the number of flats they’re getting relative to equivalent tires. It’s a great overall tire but a bit behind on puncture resistance.
And pretty much no one should be recommending the Pro One for anything. It’s slow in its category and rides no smoother than the GP5k (like a garden hose). What do you get in return? Not grip or additional puncture resistance. It’s a tire that lags slightly in every way. It’s good enough to wear out before upgrading, if your new bike came with it. But not good enough to spend your own money on it as a replacement.
