So I thought I would report back.
I got a pair of Pro 4 Endurance tyres from
ribble, I was going to save them for some wheels I am having built but I was swapping wheels tonight for some Shimano R501's I got cheap from Ribble to make do till my wheels are finished and I noticed that the back one was worn out so I thought I might as well try the Pro 4's out.
They are a hell of a lot easier to fit than the Durano's are so here they are on my bike and I will report back when I have had a few rides on them:
