It's all thread pitch, 1.25 means there is a thread every 1.25mm and 1.5 means there is a thread every 1.5 mm. It has nothing to do with the hole. Also the 10.9 you see stamped on the stud end indicates the grade of the fastener.
I've heard that before, but I don't see a PVM 7 spoke on the market in this desgn, I see a Marchesini 7 spoke; although it is slightly different then the HP4s. I do see what looks like a germany stamp on my HP4's wheel which would probably suggest PVM. Any real proof of them being PVM?

Thing is, even the PVM sprockets use a 10mm bolt. The bolt pattern is the same as the Marchesini/BST. The center hole is a different diameter (just looking at specs) though. So we're still stuck with stock until someone creates something new, as far as I can tell.
The stock wheels on my 2010 have a rear sprocket designed for these wheels, when I switched to OZ wheels it required the use of a sprocket to use on these wheels, it came from Driven since the mounting points use a different configuration. I also switched wheels on my 03 Ducati 999R from stock Marchisini, to mag Marchisini's, these too required changing the sprocket carrier, even tho they are made by the same company. Just the way it is. Fran
