    You just screw the top adjuster into the spring to get the rate you need, ingenious design:

    Ok by locking off part of the coil you change the ability of the spring to resist... interesting, but there must be downsides surely.

    yep the downside is k tech and ohlins etc etc cant charge you 80 for another set of springs,,

    No downsides as far as I'm aware. People are winning championships on them.

    That is an excellent idea.
    There prices are good too

    Surely the spring is made to a certain length for a reason, Alex is right, change the length and change the reaction, you're reducing the amount of travel therefore reducing the optimal area of use?
    Speed doesnt kill, its how fast you stop.......

    This is what I was thinking...you're reducing travel.

    Re: DDC Suspension

    I'd be surprised if the spring is compressed anywhere near its maximum, when the forks are fully compressed. This is 100% just my thoughts from an engineering point of view, I have very little knowledge of suspension.

    Springs

    If you reduce spring length you are effectively reducing travel and increasing stiffness. You would probably need to to revalve the suspension as well to take into account the decrease in travel and change in stroke.

    Agreed and I can't find any diagrams/cutaways on the interwebs, accurately depicting what happens, through the stroke of a normal spring.
