I've got a 2003 Trek 4300 with an In Sync Grind 323 fork. I realize that the prevailing opinion around here seems to be that the best way to service it is to replace it, but that's not an option just yet. Just looking for servicing info, like how/when/where to add oil to the shock. Is this simply a clone of another fork? I can't find info on this one on Trek's web site, and Google mostly turns up unfavorable reviews, but no technical information.

I'd even settle for a link to a website this company (In Sync). So far, no dice...
Thanks,

Ditto that. I rode mine until it bottomed out without any force. Then I decided it just might be time for a replacement and upgrade. ;)

If I recall correctly, these InSnyc forks were made by Answer. I doubt Answer will have any service info. They just aren't really worth servicing.

Can I assume from your post in another thread that you found the info you're looking for?
See PDF manual at http://www.spinner-usa.com/sf_sport.html

The instructions for the 2005 model should be very similar.

I think Justin Timberlake use the Reynolds Ouzo Pro fork. Hope this helps.

Yes, the post in the other thread finally led me in the right direction. Thanks!
