I found these, but are there perhaps other european based sellers? I don't think DT officially makes them?

tried googling DT Swiss ConKit 350 100 9mm ?
Did not, that looks good thanks!
you get them mostly on german sites but they are bloody expensive for endcaps. cheaper to use one of the 15mm adaptors and run a standard QR.
how about 15mm end caps and a 9mm thru adapter
I have a 240OS with 9mm end caps for my kids bike. super hard to get hold of so I've pulled them for potential future needs as that bikes for sale
i use a nukeproof 15mm to 9mm qr adapter. it cost about £15
Yes they do, though most place list it a road only the part number appears on the DTSwiss MTB hub compatibility chart. I have one and it works just fine. Also cheap at Rosebikes (£8.98).
