When a post ride tire inspection revealed that my ancient rides were beginning to disintegrate, it was time for an upgrade.
This year's revision of the PRO3 is not a disappointment. The tire feels extremely durable and has a great "road feel." I opted for the larger size, 700x25 since I tend to ride for enjoyment and like the additional comfort of the larger tire.
I haven't had them long enough to speak to their long-term durability, but I have no reason to doubt it at this point. I will report back if that changes.
