What freehub do I need? 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?
I suspect the only way to get a certain answer to this is to contact your countries Merida distributor:
