A Shimano cassette lockring remover tool certainly deserves Tatort/CSI ruler treatment, €20 for a piece of steel (same in UK, NL and DE) is near criminal!
one good thing is motor cable isn't on same side as cassette (as on other hub motor #ebikes), that limits the type of tool you can use as the cable must then go through the hole in the middle!
I'm not in such a great hurry to replace the cassette anyway as I don't use the 11t cog that much but at least I now have all the bits..
@gemlog although various clones of this tool exist, they seem to be made of much cheaper metal (there is nothing in the middle price range between these cheap ones and the genuine Shimano tool)
What is more annoying is the 11t cog is apparently sold separately, but is nearly unobtanium outside Japan, or priced about the same as the entire cassette! (possibly also due to EU import duties/tax régimes, as bikes and parts thereof cost just about the same in UK, DE and NL)
@vfrmedia Sorry about your frustation, but I did smile at your reference to unobtanium...
@gemlog to be fair the whole cassette isn't too bulky (surprisingly lightweight for ferrous metal) fits easily in my panniers, but I also then have to take the old one back to my workplace (there are periodic transfers of scrap metal items to the recycling centre in the next village).
these components are more usually sold to bike shops, but good ones are thin on the ground here and their mechanics overloaded with work (and not all are experienced with #ebikes either..)
@vfrmedia Inventing expensive new tools for proprietary new fasteners is a favourite of the auto industry too.
