    Well with that amount of grease you could grease the top of the headset, and both wheel hubs.

  2. For cup and cone bearings like that, more is fine. The excess will get squeezed out when it’s assembled. Just wipe it down when you’re done so it doesn’t turn into a filthy mess after a few rides.

    There really isn’t “too much grease” in bicycle terms, granted you wipe away the excess and it doesn’t attract dirt or get on your clothes. I’m excluding specific cases like freehub pawls where you are likely to use oil and if you do use grease you use very little and a lighter type.

    In industrial use, the bearings should be filled about 1/3 to 1/2 because too much grease will create resistance, cause churning, make the equipment less efficient. Keep in mind that it’s not the grease that lubricates so much as the oil that the thickener in the grease carries.. think of it like a sponge. You want a sponge that stays wet and keeps the inner surface lubricated (with oil). You need just enough grease to accomplish this, no more.

    But because bicycles aren’t high speed or high temp bearings (relatively speaking) overfilling isn’t really an issue that could lead to lost efficiency or vibrating or overheating so we generally pack everything with as much grease as we can because that has the added benefit of increasing waterproofing and keeping moisture out.

    No such thing as too much, really. The excess will squish out and you just wipe it off. I always pack my bearings like that.

    The NSFW tag on this was concerning. What, exactly, are you using the grease for?!

    To answer your question, as long as the grease stays inside the bike and isn’t gumming up anything it shouldn’t be then there isn’t really such a thing as too much.

    This is about 3 times as much as I use. You really don’t need that much grease because it’s not fast rotating bearing.
