I just splurged on a PowerTap wheel and will be swapping it back and forth between my racing bike and time trial bike. On my old wheels, one of the hub bodies has grease on it, the other one doesn't. I looked on the Park Tool and Sheldon Brown (bless his soul) web sites but couldn't find anything.
Is there consensus on whether greasing the splines on hub body matters? For the time being, I'm not going to grease them until someone explains why it would make a difference. Once the cassette goes on the hub body, it doesn't seem like it would need grease but, then again, what the hell do I know?
