Does anyone have any serious miles on the PR4 Service Course or the PR4 Endurance and can offer an opinion?
I don't have "serious" miles yet on them but I did break them in with a few hundred miles out in CA a few months ago, mostly on mountainous terrain.
I rode the 23mm PR4SC coupled with HED Ardennes at 90psi (145lb. rider) and they rode phenomenally.
They "feel" a lot more grippy than GP4000s in the corners and the ride quality is excellent. I like the feel or the PR4SC better than Vittoria Open Corsa CX's, which, to me, feel too plush.
The rear wheel has slight wear and I would guestimate that they would last about as long as Vittoria Open Corsa CX's.
