Resurfacing this thread. I'm at the end of my Rosso IIIs and looking to something with longer life as I hope to do some longer trips this summer / fall. I've pretty much only run Pirelli on this bike and have few complaints, they handle well, provide traction all through their life and recover predictably on the occasion something causes them to slip. That said, maybe I'm missing out. I've been thinking about the Metzler Roadtec and the Road 5s as well. Goal would be to maximize mileage without sacrificing traction on rough, twisty backroads. I suspect any of these three will perform pretty well, but based on this thread anyway, it sounds like the Road 5s are great.
