I've got the 4.5 ARs. I bought them from a shop 250 miles away, had them set the wheels up for me so they were ready when I picked them up. Kind of a gamble on reliability, but it's a favorite mountain town so any excuse to go is good for me. Haven't needed to though. They came with Enve rim tape and valves. I considered getting my own valves in a color to match the frame and would have had to go too long, so I've just stuck with the ones they came with. Sounds like I need to continue, thanks for pointing that out. 🙂
