    Spinner Grind 24" forks leaking oil

    The Spinner Grind 24" forks that came on my son's brand new Vitus Nucleus have been weeping some oil. Does this indicate something wrong from the factory? Something that might have gotten borked in transport? Normal for these forks? I've not experienced this with other forks.

    Was that your boy whose picture I just saw from Shaums camp in B-ham doing the drop? My kid did one curb drop on that fork/bike and we ordered a Suntour to replace it. One issue is the seals, a seal that is tight enough to keep the oil in will also limit the suppleness of the fork. Welcome to the world of kids suspension!

    One of my kid's friends has a Grind 300 that came on a Kotori 20. It leaks oil with brand new seals. Gross and unsightly, but the fork should still work fine.

    Ahhh, that's an interesting point.

    And if that's the case, so be it. The fork seems to work just fine for him. If it leaks a little, I guess that's no big deal.

    I'd actually be less worried about the slight amount of oil coming out than the dirt getting in. You might want to do a earlier initial service to see if the oil looks very contaminated. In the meantime wipe off the stanchions regularly and keep the seals clean (spray silicone lube on stanchions, compress fork a few times, and wipe off the crud that comes up).

    The spinner forks don't really have lower oil, just grease from the ones I have seen. Grease is basically oil held in some type of binder. The seals on Spinner forks aren't great to bad.

    I'd say wipe off the grease. There will be some dirt getting pulled past the seals. It's quick and mostly painless to pull off the lowers and wipe the dirt out of the seals and add some new grease.

    Any thoughts on how often I might want to do this?

    wipe off the grease every ride.

    I just pulled the lowers off on son's bike. He's on a 20 inch. The seals were dirty. I put in some new grease and the fork felt the same. Kind of poopy. I think fresh grease and wiping the seals will mostly keep the stanchions from getting scratched. Not make the fork great.

    I don't have a great suggestion. Every 10 rides. When it's time to change a tire. If you're adventurous you can teach your kid how to do it.

    Sorry, I should have clarified, I meant for pulling the lowers.
