    Ultegra Hubs Open Pro Grease coming out

    I have some Ultegra Open Pro's I got earlier in the week. I put a good set of tires on them and some tire liners (added about a half hour to the process) and road on them for the rest of the week. I've done about 120 miles on them this week and the grease is starting to spin out of them. It looks like a significant amount; it covers the whole outside of the hub cap. Is this something to worry about? I just bought some phil wood grease from REI and was thinking about repacking an old set of wheels.

    My question is should i repack new wheels? The grease coming out of the hubs seem very runny.
    Also, any trick to putting in the tire liners? At one point, out of frustration, i was thinking about gluing them in place. I know that is a bad idea but does anybody have any tricks for these?
    Thanks in advance!

    Grease leaking out is better than dirt getting in. Were the hubs overhauled before you bought the wheels?

    Many mechanics, me included, overpack hubs and they will "leak" grease for a few rides but the extra grease forms a fairly effective seal after that.

    Good point about better than dirt getting in.

    Wipe away the grease and see if the problem continues, if it does you might have a problem.

    I've noticed the same thing with the grease Shimano use in the Hollowtech II bottom brackets, it seems to thin out as they run in.

    Thin grease is generally good lube for the lowish speeds cycle bearings do as it coats everything

    +1. My new OPs with Ultegra hubs bled grease for weeks. It will eventually stop. Just keep wiping it off periodically in the meantime.

    +1. I often have extra grease seep after I repack. Wipe and go. Check for grittiness regularly, if you're concerned.

    Yeah, but the leakage I produce eventually stops. British cars and motorcycles leaked forever.

    Oil and grease out, water in.


    BTW, factory assembled hubs are greased by pressure-fed guns. The result is too much grease that leaks out until it reached equilibrium.

    Just clean it off until it stops.

    Had a Brit mechanic tell me they are designed that way to keep the seals moist and clean.

    Beats coming up with modern materials that don't require puddles on the garage floor.

    True.

    Years ago some motorhead friends and I wanted to market a microchip for ex-British car owners who had bought Japanese cars and couldn't get used to the reliablity. The chip would cause random failures throughout the car, the failures would correct themselves for no apparent reason and then something else would go wrong.

    The idea never got past the first stage; we probably decided to just have another beer instead.
