I've seen mixed messages across the web.
I have a wheelset with a front 240s (15mm) "Fifteen" hub. Is it possible to convert this to 9mm QR? If so what kit do I need?
Or is my only option one of the conversion axles?
Centrelock Fifteen? Looks like you need HWGXXX0002328S?
Conversion chart here:-

I've the 15 with qr, then converted it to 9mm thru dt rws. DT website has a list of adaptors for each hub.
As per that chart if its the centrelock 5/100 disc brake centrelock it's "Not available".
Mine is Centrelock, so it definitely exists, as per SOMs part no.
Madison code HBDT2328S
Any shop will be able to get them.
Spline wheelsets have 240 hubs but need a different qr9 adapter than listed for 240 classic/straight pull hubs only.
Spline 1's use a lighter hub shell and axle than the standard 240's, hence different end caps.
The converter I posted above is for the standard centre lock 240, which is, as far as I can tell, what you have.
