Yeah, I got my pair of GP4 Seasons in about 10 days also, correct order. And they were a ***** to mount, much harder than the 2-3 year old set I ordered from Wiggle back then. Conti must be making them smaller these days, as the previous pair was pretty easy to mount, even on Ambrosio Elite rims. The new pair went on Mavic MA-2s. Thumbs were complaining 2-3 days later and though I was going to break some Pedros levers getting them on.
Also I hadn't noticed, but the new ones are all black vs. the brownish sidewalls on the older pair. Prefer the older ones, which are still the Vectran as well.
