Question about suspension and saddle on Trek 3900
I just bought a new Trek 3900 (2007 model) and I'm just wondering how the suspension fork is adjusted. I know that there is a little knob on top that you can rotate one way or the other, but I can't really figure out what this does or how I should set it, which way is stiffer or not as stiff. The generic Trek manual I downloaded doesn't seem to cover specifics like this.

When I bought my bike recently the fork had a manual with it...perhaps you could go back to the bike shop and get that manual. Sorry I don't have a straight up answer, but I am unfamiliar with the forks on Treks.

i think it is an InSync Grind 1, 70mm travel i don't know much about it, but i doubt you can adjust it much. does it have pictures near it? a lock? or a rabbit / turtle?

I believe the knob is a preload which squishes down the elastimer to make the shock feel stiffer. I had a similar shock on my bike and my wife has a similar shock on her (but different brands entirely). I liked mine adjusted mostly soft and my wife liked hers adjusted full soft. It's a matter of feel, but IIRC it takes a lot of turning before you can feel the difference.

It's not at all like a damping setting that feels different with every 1/8th turn "click".

Well I figured it out...had to turn it a LOT it was on full soft evidently. I did get it adjusted properly with 15% sag as recommended.
