Just at work so I have no tools here.
I need to know the exact size of the hole a front or rear QR needs.
I'm getting some step up adapters made to convert a QR to 10mm to allow me to build some wheels in a normal QR jig but I forgot to measure the size of the hole I will need.
Eg the inner diameter of the hole on the right that the QR goes through.

Thanks
according to my verniers its 5.2mm*
*i think they're accurate. if you call hope theyll tell you the actual size. 01282 851200
Well I learned something new today.
My hope QR adapters are hex shaped internally. Near as I can measure the hole varies from 5.2 - 5.4mm.
My hope QR adapters are hex shaped internally.
Is that on a bulb or xc?
That's on a Pro III. And front BTW.
Do you want a non-Hope one checked?
i believe the pro III screws together to preload the bearing. hence the hex head.

Makes sense.
Standar QR skewer is 5mm if that helps
wouldn't a front hub conversion to a thro axle be to a 9mm? and the rear 10mm?
