    A visual to suspension....ask away!

    So, many people wonder what the heck is going on inside!~~~????

    Well, a lot!

    In fact, so much, that even the top engineers are still tweaking and designing to fix some limitations to suspension.

    BUT, some things to consider!

    You only have x amount of travel! So, say you have 11 inches of travel. No matter how hard you try, no matter what you do, your stuck with 11 inches of travel. You will never be able to not feel a twelve inch bump if you catch my drift.

    Next, is that suspension is no guessing game, or witchcraft, or anything like that. It can be broken down to an exact science and evaluated accurately by the technology we have today! So thankfully with some common sense, anyone can understand it...and learn to improve it.

    Now, has anyone wondered why it's CRUCIAL to get your suspension set up for you speed....but not so much your weight?

    I will post some graphs soon...most of which I posted on thumpertalk...but I gotta run for now! If you have any questions, ask away, and if I can answer them, I will!

    how do you figure out how much a suspension will suck up

    If it does not move at first, get a bigger hammer!!

    Ok....this is just the first graph of many available...I will elaborate more as I go, but the graph is a representation of your front axle vs available travel. The line basically shows the motion of the front wheel, and 100 percent travel is bottomed out....

    So, what is all the hoopla about getting suspension tweaked for you?

    Well, take this example, one line is a novice rider, the other is a pro rider...the suspension here is identical between both setups, the bumps are identical too.
    Note, because the pro goes faster through the same bump section, he hits the bumps earlier/faster between hits.

    this is showing me that the pro suspension is stiffer/ less rebound...

    In this graph?


    No...it's the exact same suspension.

    If this shows you that the pro needs stiffer compression settings and less rebound damping, then yes, of course, and I think that's what your saying.

    As shown, he nearly bottoms in the same section the novice is not even close to bottoming in.

    So what about damping changes, and tuning....I mean, while this sounds elementary, just how much damping is required to get results you want, what does a stiffer spring result in, and what does it all mean in regards to what the rider feels?

    One thing you may already know about suspension, is that no matter who does it, there are no tricks, or secrets, or anythign like that. While many of the companies seem to make it out like that...I can't tell you how many FC set ups, or enzo set ups...or PC set ups I see....and that they all are tweaks and variations of the stock design...just set for that rider.


    While we all want to believe that when paying big bucks for suspension, you are getting somethign special, or a special valve etc... (some companies use their own valves...but most of the big ones as stated above use the stock valves) but really your just gettign a lot of their time and effort to test hundreds of set ups for each specific rider to get it just right.

    THAT's the hoopla. It DOES make a huge difference, but it's no magic!

    Anyways, anyone care to guess what percent change in damping it would take to get the pro's stuff to look like the novice's stuff through the same section?
