Shimano RM60 rear hub problems
A friend of mine has a 2007 Trek 7.2FX . He's experiencing some problems with the rear hub.
Here is how he explains it.
"On a cold day recently, I was pedaling, and the chain spun the rear gears, but did not engage the wheel. I.e. it was just free spinning. Eventually it caught, but it happened several times more. I'm told that the lubricant in the hub is gunked up and that this will keep happening in the cold, getting worse and worse so that it starts to happen even when it is 30 F. I am advised to buy a new wheel, since the hub of mine cannot be serviced. (Apparently, the higher-end ones can.)
It is indeed a 7-speed.
I am not very knowledgeable (working on it), but I'm surprised if my set up has the freewheel on the cluster itself, rather than in the hub
I got the idea that any bikes after 1980 would have the freehub. Mine is a 2007 Trex 7.2FX (great commuting bike). Trek says it has a Shimano RM60 rear hub. But I haven't been able to find out whether this RM60 is a freehub, or whether my freewheel is indeed in the cluster. Do you have any idea"
So that's it. Anyone have any ideas on how to fix this problem?
