Hi to all,
sorry that it took me such a long time to reply again. I was in contact with the maker of the tool, and asked him to modify a little the length of the shaft part (it was too short to reach to the star-like hole inside the freehub body). Well, after all, I bought 4 of those modified tools and tried one to remove the freehub from an old wheel. There is fortunately no problem with that. Just compared with the original Shimano tool, you cannot simply use a wrench/spanner to loosen the freehub but you have to fix the tool ("star" facing up) in a vise and turn the whole wheel instead.
Tomorrow, I will finally take the tool to the post office and ask about the best way of shipping abroad.
Sorry again for my delayed answer... Will keep you posted, and if anyone is still interested in the tool, I will ship it to you.
Jan
