|I got my speedplays originally prepped with regular bearing grease (semi-translucent), but I have teflon-based Finish line (white). Is it OK to mix the two?|

|For reasons I can never fathom, some folks warn against mixing greases. I can see this if you're using a silicone grease and a petroleum grease (perhaps), but for the greases I have seen in pedals, hubs, freehubs, bottom brackets, headsets, etc. I have never had a problem mixing greases. Perhaps those who fear such mixing can offer a technical explanation rather than "I was told not to."|

|I've heard and read the same type of thing. I can't remember the base types of greases, but that's what it came down to. Certain bases don't mix well. Kinda like oil and water. I've seen petroleum, synthetic, soap and vegetable oil bases, but I'm sure there's many others.
A quick search on google for "grease +base chemistry" turned up more than you'd ever want to know.
