Regardless of how crappy your suspension is, you should always have the sag set as correctly as possible. Shoot for the rider sag number, but never let that dictate zero free sag. In other words, if you want 30mm of rider sag on the shock but to get that you have to crank the preload up so much that you don't have any free sag, then back it off until you have 5mm of free sag, even if that means you have 40mm of rider sag. The reality is that if the springs are wrong for your weight, you'll only be able to go so far with it. I like to see 30mm of rider sag in the rear and 35mm in the front, but there are as many opinions of proper sag numbers as there are trees in the forest, so just get it close and tweak it to your liking based upon actual riding results. If you can swing a suspension upgrade, you'll likely be much happier with it, the difference is incredible.dafro42 said:while i was taking the snorkle off tonight i was thinking about the crappyness of the front forks and i was wondering if 1. the preload would make much of a difference for both the fron and rear and 2. what should both of them be set at.

free sag is the amount of sag the bike has under its own weight. measure it fully topped out, then just the bike with no rider. most commonly on stock springs, you may get a correct rider sag figure, but the spring is undersprung and you have no, or very little, free sag.Currently said:How do you get FREE SAG ?
Understand preload and rider sag, but free sag is a by product of what you got? i.e. spring rate?
