I've an oldish pair of hubs that have joint DT/Hayes branding, front looks remarkably like this:
It takes a 20mm axle but I've lost the spacer & dust cap from one side, as shown on the pic - it leaves just the exposed bearing dust shield
emailled Madison, who told me it was identical to a 240s & gave me a link to a part but their link to DT site was invalid. emailed them again, saying it looked different but got no reply
I found a part (by looking at DT diagrams though these weren't all that clear)
What I have is this, which DT describe as for a 240s:
(edit; link doesn't work automatically. try a pic hotlink)
Trouble is, it's unsuitable for my hub (it has some kind of internal thread that presumably screws onto hub body, but my hub has no threaded section). When I tighten the 20mm axle the new part crushes onto the bearing shield (not the internal solid "axle" bit) and the wheel barely turns)
Does anyone know what I actually need ??
