ok, so i am really sad when it comes to grease. i have preferences for different jobs.
first is the obvious one, Park tool grease, dark green in colour, pretty thick, i use this on hubs, ball bearing headsets etc. generally i quite like it.
next up is Motorex, i think this is the nearest thing to genuine shimano original grease, it's thinner than the park tool grease but i do like it, again ball bearing hubs and headsets.
next up is Cyclon grease, they call it "course grease", it's very thick which i like, it's sort of tan in colour, great for ball bearings etc.
the next one i like is also from Cyclon, they call it sealing paste, it's for sealed headset bearings etc, it's not really designed to be a grease, it's barrier to put around sealed bearings, it's really thick, it's almost white, and i really like it.
then lastly, good old fashioned copper anti seize, i use this on threads, for putting BB's in frames etc, because remember, grease is for bearings, although you can use it on threads it's not really what it is designed for, so copper anti seize is better and it tends to sty where it's supposed to be, grease will dry out.
