All my own fault.

Went full enduro n had a tube strapped to my saddle and its worn the post.

Still works fine buts got abig wear mark and shading on the stantion.

It’s a SDG telis I’d replace the shaft if I could find one but cant.

Anyone got any ideas?

Does it still work? If so, run it till it doesn’t

Never go full enduro.

Maybe paint it with nail varnish like people used to say for fork stanchions? But not so it’s got any sticky-out bits that could drag crap past the seals.

Otherwise just run it til it dies like mashr says. I have one of them too, it’s a nice dropper.
