    I wonder about the fact that they are sealed has anything to do with the longevity ?

    The stock range is between 143 and 187lbs.

    Outside of that, it appears from the email that they can put a stiffer spring in and adjust the damping to compensate (which is excellent news!)

    Just ordered mine. I'll re-spring if needed.
    Great customer service! I gave a shout for Frank. I think they are very appreciative of you, Frank.

    BTW, these are going fast! It wasn't clear when another shipment was expected.

    Frank, with the new spring rate, have you found it more difficult to bottom the front out, or is it just feeling more compliant but still hits full travel frequently?

    Bayner,

    Beacause of work and the weather here, I have not been able really push it to the limits. I did take it to work on Sunday. Staten Island NY. The roads are probably not unlike the bombed out roads in Bagdad. :lol3
    So I noticed, short, quick hits like potholes are sucked up. The impact feeling we normally get is reduced by 80% on most and completely on others. I seeked them out and some I hit hard. The fork never bottomed on this of course. But from what I can tell, I would expect full travel when the bike is g-out. But time will have to tell.
    So far, would I buy them again and recomend them ? In a heartbeat. They are a marked improvement.

    Yep, they're out of stock now, I'm on the waitlist for some indeterminate amount of time ...

    No, wait - they just called me back a bit ago, they "found" 2 more at another shop. As of an hour ago, they still had one of those left ...

    I just pulled the trigger on the last set from their first batch.

    Ordered them from Kathy by phone. Super nice lady.

    Good thing I love ramen noodles. :lol3

    Given the design of this suspension kit, I actually don't see how fork oil weight would effect much at all. Given that no oil actually enters the nitrogen-charged cartridge unit at the bottom, and that the damping and rod action is not dependent on the oil. If you look at the picture, the only place oil resides is above the cartridge itself ( the gold part). Oil weight won't effect the movement of those springs and rods that much.

    Jeez John no pressure on me ha ? :lol3
    Hey remember fellas, I havent flogged it offroad. My early assesment is they are much,much better than stock on short chop. Im pretty certain you guys are going to be happy with these.

    Yeah, makes sense that it would be an extremely light oil though. All it's purpose is in this design is to lubricate the springs against the inner sides of the fork tube. And to keep things above the cartridges from binding overall.

    I weighed myself today.... 187 exactly.

    Looks like it's "Bacon Lite" for me from now on.

    No pressure at all. I will take the setup to my suspension guy and have the springs measured. I'm optimistic this will work as is. If not, it should be able to be re-valved if necessary or new springs made.
    I've put in some calls to Works Performance for the rear. Their engineer that would handle the job is out for some injuries right now. If I don't hear back soon, trailtrick has an Ohlins available.

    If lubrication was the goal, grease would have been used. Half of the spring isn't in the oil anyway!
