I've got my hands on an old dynamo hub, with a view to building a 700C dynamo front wheel for my hybrid. It uses (I believe, and will check) an M9 solid axle, but the existing one is QR. It certainly fits without being loose, but I don't have the nuts for it and it's built up with an ETRTO 590 rim at the moment so I wouldn't have any brakes for a test ride. I already use security QRs so I'm not bothered about having to undo nuts to take the wheel off.
Is there a reason to avoid doing this, or anything I should check before ordering parts?
