It looks like my LBS damaged the freehub body on my 105 8 speed GS when they greased the bearings.
I need to get a replacement fitted.
The Shimano FH RM30 is an 8 speed freehub body, but are there specific freehub bodies for specific groupsets?
Do Shimano fit the same 8 speed unit to all the Road and MTBs?
Would any 8 speed Shimano freehub body fit OK?
