    Green grease or white grease?

    I have a 10 year old tube of white, Finish Line teflon grease that I use whenever I'm working on my bikes.

    Last night, when upgrading my rear Hope Pro2 EVO hub to 142x12, I accidentally pulled off the whole freehub body. OOPS! Pretty cool, though, as it's the first time I've ever seen the inside of a hub. Other than all the cool parts, one thing I noticed is that Hope used a green, translucent grease inside the hub and not the same white stuff I use.

    Are there different lubes for different parts or does it not matter?

    I use the same for all but where I live it is pretty warm. Not too much otherwise it gets to sticky and the hub starts binding,

    I have been told that using to thick of a grease in cold temps effects the hub in a negative way.

    Each mfg will spec their own lubes, and some might actually be 1/5th of a percent better than a good grease, but for all intents and purposes, I have thrown Phil Wood grease at everything but the chain for 30 years with no ill effects. All you need is a high quality water repelling grease for all your pivots, slides, bearings, sleeves and pawls.

    If you're using a water repelling grease on the pawls, you need to be thin with it, period. Pack too much and the pawls will float. This is worsened by cold weather. While I don't deal with Alaskan winters or anything, I find PW grease is fine on the pawls down to 16F, the coldest I've ever ridden. A thin surface layer is enough, and is all that is needed to protect and lubricate..

    Some racers will tell you a lighter grease will make you faster. I never felt a difference when I experimented with different lubes, but, ok, I can buy that a lower viscosity lube requires less energy to maintain spin. I'm just not sure it matters with the small torque angle of wheel hubs, pedal bushings and bottom brackets.
    I will suffer no butt-hurt fools!

    Thanks. So that green grease is probably Phil Wood? I seem to remember having a tube of that a couple of decades ago...teal blue tube?

    Also, the Hope "how to rebuild your Pro2 EVO hub video is pretty good about where to apply grease and how much to apply. I'll probably rebuild (or at least open and clean) the hub this winter and will follow those directions.

    I doubt it is Phil Wood. Phil's is not translucent and reacts a lot to temperature. Freehub pawls are the one place I would use the manufacturer's recommended grease. I know DT Swiss makes a big deal out of their hub grease.

    Phil's Tenacious Oil is wonderful freehub lubricant. As is DuMonde's freehub specific oil.

    I also use Phil's Tenacious Oil, not grease, on freehubs and freewheels, but I'd contact Hope and find out what they recommend since they use grease.

    As far as the rest of a bike I use both Finish Line teflon and Phil's Waterproof grease based on odd quirks that I have evolved over the years. Finish Line on hub bearings, Phil's on most everything else with loose bearings and also stuff like bosses, threads, seatposts, etc.

    I think it's ok to use thinner grease in Hope freehubs, you just need to check and replace it more often.

    You really don't want to use thick grease as it might stop the pawls fully engaging on the ratchet ring. If a pawl just catches the top edge of a ratchet tooth it might snap it off!

    Different designs of freehub need different lubricants. It's important to understand the design of yours and make sure you use the right stuff.

    I think a lot of the fancy bike-specific lubes are a lot of bollocks. Bicycle bearings is not a very demanding environment for a lubricant and there are plenty of commonly available lubes that work just fine. How often you change the lube and how good the seals are is usually far more important than which lube you choose.

    So I watched the Hope video on rebuilding their hubs. It's a very good video but the guy uses what looks like some pretty thick grease to me.

    If any of you wants to take a look, what are your thoughts? No where have I seen them post their recommended grease.

    Forward to about the 8 minute mark to see the reassembly and greasing.

    Not to hijack but.... what to use on the fork dust seals? I drop one drop of Phils Tenacious on them when they look dry. It spreads all the way around in a few minutes.

    Any other key points that need grease/oil on regular basis?

    That is another topic that really deserves its own post.

    Anyway Kevin the grease he use looks to have about the same viscosity as the park tool grease that I have used.

    Once I packed in too much and the freewheel didn't work all that well.

    Basically just enough to fill the teeth.

    ^^Yep. Parks polyurea is pretty thin and works well, never used it under -20F or so though. Slick honey would fit that bill as well, if you have it.

    (BTW, thread hijacker, get some slick honey. )

    The "grease" in the Hope freehub is 00 grease (zero zero)

    It's more gel than grease. Often called gear lubricant.

    This is the best price I've seen.

    I have used Phil's in my star ratchet hub for years without issue. Put a little more in than you think you need and it quiets them down nicely too. YRMV

    Just for the description alone I would like to try it.

    Super S Cotton Picker Spindle Grease 00 is a smooth textured, corrosion preventive grease manufactured with a special low viscosity, low pour point base oil with a lithium thickener, as well as rust and oxidation inhibitors. It is recommended for industrial and agricultural applications calling for a low consistency product with low operating temperature properties. Super S NLGI 00 Grease meets or exceeds the John Deere JDN-360 and JDN-380 specific cautions for cotton picker spindle lubricants. It is widely used in gearboxes on bush hog type cutters and some gear cases on riding lawn mowers.
