    Is this why it is important to set the rebound clickers before compression?
    In conventional cartridges where the bleed paths arent one way check valved yes you should absolutely adjust the rebound first and foremost as it can make a sizable difference to compression damping. With BPF forks its HUGE. Compression adjustment has almost no measurable affect on rebound damping.
    In a conventional cartridge with a base valve assembly and lower compression piston the compression only acts on shaft displacement and that is variable according to the diameter of that rod. As a percentage of total damping it is not as significant as one would think, especially when combined with a modern ''bending shim stack midvalve. Ohlins even call that midvalve the main valve as it just about becomes the main tuning component. An extension of this thinking is to completely remove the base valve and all the compression damping is then on that midvalve. Make the left fork totally a compression fork and the right fork totally a rebound fork. Absolutely no cross talking! More and more manufacturers are embracing that design concept, its nothing new.

    Great read Robert. Thankyou for sharing, its always good to learn from such a knowledgeable genuine guy.

    Regarding cross talk.. I read somewhere (dont know if it's true) that the Racetech 25mm cartridges dont suffer from this due to their design. Is this true or is it BS, If true.. Could you please explain how they work.

    Thanks

    Are there disadvantages to doing this?
    I've always wondered about flex through the front axle if you do, wouldn't it also give more tendency for the fork slider to bend/distort and bind?
    Could this be done with any fork, or only certain designs?

    I remember My old KTM from '85 had this setup on the old rwu damper rod marzocchi forks way back then...

    Weve tested the Race Tech cartridges and they do work very well, but they still cross talk a little.

    With older designs that arent clamped together so well with spindly axles yes it would be an issue. But with modern forks and large diamter well clamped axles no problem.

    They felt every bit as good as FGK cartridges!
