Yesterday I was giving one of my bikes a bit of a cleaning after a rainy ride. I have noticed this in the past but finally decided to address it. There is alway grease "leaking" out of the hubs. Primarily the front. The hubs are Shimano 600 Tricolor.
When I service them I lay a bead of grease then set the bearings then another bead on top before the cones are installed.
Thoughts?
