Having difficulty getting the second 20mm adapter off without drifting the axle out and now may have damaged the threads
Arse
Grip the end you've already taken the adapter off in some soft jaws in a vice. Then you should be able to unscrew the other end with the correct sized cone wrench.
Madison are the UK distributor for DT Swiss hubs, any LBS will have an account, so if you need spares, pop into your LBS and show them what part you need, and they should be able to order it for you.
It was in gripping it (instead of drifting it) that I ripped a good 10mm of the threaded circumference off
Thought I could just hold threads and spin it - drifting didn't seem to work
Adapter screws back on fine and I'll get back to drifting it tomorrow once I've calmed down but good to know spares are available
Cheers
As long as the adaptor still screws on, it should be fine. Wee warning, I usually clamp it in the middle, a couple of sets of mole grips have always been adequate for me but I did slightly deform the axle last time by squeezing it too hard, which was annoying. Not hard to fix but still.
I'll grip it with the old maxle inside - should help prevent any deformation
Just need to get it out now!
I think I have always had to drift out the axle first but once out I've always managed to pop the end cap by twisting an old inner tube around the axle (really tight) then spanner on end cap as normal.
Best to wear a glove on the axle/inner tube hand for the ultra mega grip without leaving your dainty hand sore.
