18mm OD dropout measurment

I’m looking at these QR fork dropouts. I noticed that the description says they are for an 18mm OD fork blade. But the design seems to socket into the fork blade, so it seems to me like the ID is what actually matters for compatibility. Is there something I’m misunderstanding?

Thanks.

Yes, that’s strange. Of course the ID matters. But—looking at the Allotec catalogue, there is no dropout with this OD and weight and look combination? http://www.allotec.com.tw/

Hi John, sorry that the description is vague, i will update that.

The insert portion measures 13.8mm and at step shoulder area of drop out measures 17mm.

The 18mm in that description was carryed over from the thru-axle style which is slightly bigger.

Thanks,
Carl
