The bearings in my freehub are starting to go and I'd like to replace the part. Sadly I have no idea of the part I need to replace it with and cannot find anything specific. My bike is a Merida 140 2016 with a 10 speed shimano rear cassette. The hub specification I can find is limited to "Rear Hub: Bearing Centerlock- 12mm rear" with a slightly better model saying "Rear Hub: Shimano XT 12mm rear"

Searches for 10 speed shimano freewheel don't give me anything that looks like this.

Anyone any ideas what would work?

    Is there anything written on the freehub itself? Commented Apr 8, 2019 at 13:27
  • By the way: Could it be that you didn’t tighten the cassette nut enough? Those grooves look like they were caused by a loose cassette.

  • Freehub - hub connections are like derailleur hangers - so many different formats!

I suspect the only way to get a certain answer to this is to contact your countries Merida distributor:
