Bearing grease: What do you use?

    I need to add some grease to the left bearing ring and dust cover on my Shimano CB-E110 coaster brake hub after making some adjustments to it that required cleaning away some of the grease.

    The stock grease that came in this new hub is black. I see many different colors of bearing grease in stores. And different formulations...lithium...synthetic...etc.

    What's typically used on such hubs? And can you mix greases? That is, I've already got most of the original grease in the hub, and I just need to add some. I don't want to tear the whole hub down and start with all new grease because this hub is showroom new.

    On a couple of "spandex biker"-type forums, I don't see any consensus on which greases are best; just lots of different opinions -- and even arguments. Some people say that they use plain old automotive axle grease from a tub. Others swear by fancy, expensive brands in little tubes from bicycle stores ("Phil Wood" grease seems to be the "ultimate" for many of these guys).

    I feel that a good axle grease, (I use STP), we use in our vehicles (and we are doing 70MPH) is good enough for our bikes doing less then half that.

    Maybe an idea is to call the major oil companies and ask to be transferred to their technical department for advise on your question.

    I am sure you would find at least one company that would give broad based technical advise.

    It's never a good idea to mix grease types or generally just add more to bearings without a thorough cleaning but if you satisfied the grease has not been contaminated, best would be to replace what the manufacturer used, Shimano Internal Hub Grease, it's black and contains graphite.

    For almost all other applications on a bicycle: hubs, headsets, BBs, fork sliders, swingarm pivots, I have come to prefer Buzzy's Slick Honey.

    Specifically, I'm using DuraBlend bearing grease but that's just because it was what was at AutoZone. Any brand name synthetic wheel bearing grease will work great.

    Good advice and I'll second the Buzzy's rec, great stuff.
