@uggski the XTR M9100 has a completely different spline to the XT, but the second video is exactly the same as mine.

Either way though, the tool is the same for both models.

Ok, well seems like I’ll have to bite the bullet and send this back and wait for another tool…grrr.  Seems very odd though for Shimano to manufacture something so far out of tolerance.

Seems to be the right tool according to the part number too.  Its got Shimano TL-FC41 stamped on the side

I did one better @kelvin did a brief video..

Wow, you guys had some pretty posh bikes.

My first full size mountain bike was a Dawes Tracker (19″) which I got for Christmas when I was 12 I think.  C.1990.  My friends had similar bikes (one had an Emmelle the other I forget which brand).  I remember the Shimano group sets on them all had names.  Shimano Exage Country was mine, the others I think were Trail and Mountain.

Around 1993 I bought my first mountain bike magazine (MBI), and on the lowly budget of a paper round began modding my Dawes.  Kept it for years and changed pretty much everything in it, frame was professionally resprayed Yeti green, even had a Synchros seat post and stem…on a Dawes!

No idea what my parents paid for that bike, but I certainly sunk a whole load more cash into it over a number of years after.

@carlos email sent! 👍🏻

@brianblessed super stuff, thats just what i needed.  thank you!

@carlos i’ll take the HUB229S please, it looks like i’ll be needing it!  I couldn’t send you a message for some reason, so not sure how to arrange.  Let me know tough :)

@Carlos Yes, partly.  I read that thread last night.  What it didn’t confirm was whether converting my hub using those parts would allow the new Microspline free hub to fit properly.

My other option might be to leave the hub as it is and use an MZ90 12S Sunrace cassette instead..
