    are these realy adjustable? (rockshox xc 28 rebound and preload)

    I think I have no luck with them.

    Top left preload knob gives me no differences and when I play with it, it seems turning won't stop. no click sound.

    Do I just turn the knob to 90 degree to left or right to adjust rebound?

    I know its entry level of rockshox but don't know why do they put adjustments on it.

    I tried to find how to do that properly but no luck.

    and one more pix before I broke the chain. too much torgue on it.

    The pre-load adjuster doesn't click on mine, but turning it does affect it. I've dialed mine up quite a bit as I'm a "hefty" boy and I can tell the difference in how the fork squishes - for lack of a better word.
    The rebound adjust is simply quick, neutral, and slow settings of return based on how you turn the lever. I noticed very little difference at first between any of the settings but after breaking the fork in a bit and paying attention to the different settings while riding trail, I've found a setting that works for me and my terrain.

    I was in the same boat as you...couldn't figure out how to adjust it properly. Finally, I just took it apart and looked it over. Do that and you'll have a better idea of what it's doing when you adjust it. I got it adjusted pretty well for the trails I ride and my weight.

    I just dont understand bottom rebound adjustment.
    Mine was off from fork when I got my Gurdian. Like you see third picture. It was off so I put it in.
    So just turning it 90 degree to left or right is adjusting rebound?
    or Do I need to take the knob out and turn it?

    I didn't know it came out. That might be a problem. Yeah, it just turns to the right or left to adjust rebound speed.

    Like someone stated above my pre-load does change stiffness but it does not click. I have played a little with the rebound adjustment and it doesn't seem to make much difference. However the knob has never come off....I would say that might be a problem.

    The knob coming off isn't a problem. It's a snap-fit knob, that fits that way because it has to be popped off when rebuilding the fork and removing the lowers. The knobs on the Rebas and SIDs are the same way.

    Just pop it back on and go.

    I weigh about 200 lbs and I have the preload cranked all the way up. It works fairly well on the type of trails I have been riding, singletrack and ATV trails with lots of roots. However, judging by the dust rings on the stanchions I am using about all they have to offer. I feel like they have been performing well enough, I'll ride 'em until they break.

    There are kits out there for $23 to replace the medium springs with firm springs. Anyone done this?

    I lost my little black knob, is there a way to adjust it with an allen key or do you need the black knob piece? What size is the allen on that piece?

    adding preload to a spring does not change spring rate, So you will not notice much a difference when adjusting it. All adding preload does is change the amount of force need for the fork to start moving. Once it starts moving, the adjustment has no effect on the fork. For example, say it takes 500lbs of force to bottom out a fork spring, there is no adjustments that can be made to the spring to change the fact it bottoms out at 500lbs, other then changing to a different spring all together. What the preload does, is compress the spring from the start. Say it takes 20lbs of force to compress a spring 5mm that has no preload on it. If you add 5mm of preload to that same spring, that same 20 lbs of force will no longer compress the spring at all because its already compressed as much as 20lbs of force will allow for. In simple terms, preload set the force needed to start fork movement. Nothing more, nothing less.

    rebound controls how fast the fork returns after a compression. It should be set based on the spring rate(Stiffer springs need more rebound damping, softer spring need less). Unless you changed from the stock coil spring, the rebound should be set pretty much in the middle of the range and forgotten about.

    hope that helps.
