To sag or not to sag?
Posted December 31, 2007 - 08:35 AM
My bike now has a lower center of gravity and it seems to be easier to toss around and negotiate trails and hill climb.
My question is, is there any chance down the road I could damage anything from doing this?
I appreciate your advice. I've used many of tips from TT to fix and keep my ride going.

you're probably going to be unstable at higher speeds. your bike may swap around or handle poorly when going over bumps at speed.

Hurt the bike...don't see how the wrong sag could do that but if your sag isn't set properly your suspension isn't going to work properly.
Race sag on your bike should be around 4 inches and static sag should be 3/4 of an inch or so. 5.75 and 2 inches respectively of sag means your suspension can't operate to its fullest potential. The preload needs to be increased to get it to the right sag ranges. If the seat is too high then you need a lowering link. You shouldn't try to adjust ride height with the preload (except in very small increments while still maintaining the correct sag ranges.) Same with ride height. As tall as you are, the ride hight should be just fine with the stock springs. I'm 2" shorter than you and weigh basically the same so I know it can be done with the stock suspension. (I still have the stock springs and mine is set at 4" and 3/4". No lowering link either and I have a 30" inseam.) It is amazing what setting the sag properly can do for you- you don't know the difference until you do it.
If you are indeed a newbie to riding (not just to TT) it may not make that much of a difference. But as you get more experienced and you want the bike to behave to its fullest potential, the sag setting will become more important to you. In other words, if you plan to just putt around then disregard everything I said. If you want to go fast, then listen to me, grasshopper.

I agree with the ~4" of race sag, but I think that static should be less, about ~1/2"
Lastly, at 200 pounds both sets of springs would be light. I replaced mine with a higher rate and had them rebuilt/revalved by MCR. That makes a huge difference.
