Hey Mike, i can lay hands on 4 to 5 mm adaptors.. (they come as a set, i don't remember the exact numbers, i thought it was a set of 4) 4-5 5-6 6-7 and 7-8 mm

Dafni- "soon" is the key word! The newer wanderers will be a little while, I am sure.

Serum - What adapters are you talking about?

Ja, "soon" is indeed a broad term. Usually it means 6 weeks, LOL, but don't be surprised to hear "soon" again, if you ask 6 weeks later.
Anyhow, I was told the Wanderers will have a screwed-on bell, and it's possible to upgrade to the new rotor later on. So I think I might try the current version, to get a comparision.

I think Serum meant some spacers for the shafts, like 0.5mm sleeves.

Yeah!

10 points for Switzerland!

I may be interested in this bore reduction set. 5mm to 4mm would be the one I need, but if it is a set, so be it!

Funny story: I posted the comment above in Serums post (must have hit edit instead of reply). I just moved it to a new post to share the story.
Daniel, you still get the points!
