If its a normal qr it'll be 9mm not 15 or 20mm.

Pull the qr skewer out of your current wheel, should be obvious which one it is or measure it if you have to

I'm not sure what you mean. My current wheels are QR and on the Fulcrum spec is says "QR/15mm thru-axle adapter kit for the front wheel included".

Sorry, i didnt see that bit. A 20mm axle hub will work with a normal QR with adapters. If you dont need the 20mm compatibility (if you had a 2nd bike or plan on upgrading your forks soon) then it would make more sense to just get QR wheels. These will fit on your bike with adapters though.

If you're measuring it, remember that the size refers to the axle, not the skewer (the skewer will be 2-3mm). The 9mm axle on a standard QR doesnt come out of the hub. A 15mm or 20mm axle will come out, so you can measure the axle.

good point

basically if its around chop stick size its regular QR, if its more like the thickness of your thumb its 15 or 20
