    XT threaded headset Ė dust seal?

    Was there a dust seal on threaded XT headset between crown lace and bottom headset cup? Itís the one with loose retainer bearings in it, not the cartridge one. I donít find a seal in my box but it was from years ago Iím not confident if I had it kept all in one package properly. I noticed the grease oozing out after a ride in a hot day, it made me wonder. Thanks in advance.

    I just repacked one over the weekend and there is a seal for the crown race/lower cup.

    I'm not sure about the effectiveness of the socks as it drips after riding hard.

    Hey Shayne, was it just a circular rubber seal that or was there a metal base that sits on the race/bearings interface? If so how/where does it sit?

    On a added note, do you know of any "replacement" sealed bearings that can pop into these cups? Doubt it, but these bearings are significantly oversided compared to other loose bearings that I have.

    Thanks guys.

    Its a thin plastic(Ņrubber?) ring that sits on the edge of the race. It looked the same as the seal on the top half of the headset but I wasn't paying all that much attention. I can get a photo of it later.

    That would be wonderful, thank you for that. I just need to know what to look for in my junk box :-)

    While these oversized bearings are super smooth, durable and nice, the headset weighs a ton compared to regular threaded headset.

    The seals are plastic, a good bike shop might be able to order them. I would cut out a 1 inch piece of inner tube and slip it over the bottom cup and over the crown race when the fork is installed, works great.
