Well, only RS has an adjustable negative spring as far as I know, and IMO it's critical. The fox versions use a "self adjusting" air spring, but that is always going to set to a certain value depending on the positive pressure. You simply can't do the tuning that you can with the RS "dual air" versions.Bikeeveryday said:what is the big deal?

mine got worse and worse until it was basically a platform fork, due to stiction.. and it had oil in it. its just a bad fork.graftoon said:will a dart 3 eventually break in and become less stictionless?
Do remember that the dart series is Rockshox's lowest entry level fork series, meant for bikes that are only for beginners off road, so dont expect performance thats on par with their high level forks with better spring systems and dampeningtomsmoto said:mine got worse and worse until it was basically a platform fork, due to stiction.. and it had oil in it. its just a bad fork.
There is hope, make sure there is enough oil in the lower legs, and teflon lube the stanctions. I did this to a dart 1 (even crappier) and while it's not as buttery smooth as my Pike, it does feel better than when it was new (because there was no oil!).graftoon said:will a dart 3 eventually break in and become less stictionless?
I think this is wrong. I think stiction comes from the seals and the bushings being tight.what is the big deal? Most air forks have negative air springs to reduce friction at the first bump nowadays. Get a fox or a rockshox. not much stiction there. rockshox even has a negative air chamber to tune out the stiction.
That graph is showing that preload can be eliminated with a negative spring.A negative spring allows a fork to activate at a lower force without greatly affecting the rest of the spring rate through the rest of the travel. So while it doesn't eliminate stiction, it helps feel like it did.This graph (which I blatantly stole from another thread) helps explain it quite well:
I don't think preload means what you think it means.retro83 said:That graph is showing that preload can be eliminated with a negative spring.
Stiction is constant because it is nothing to do with the pressure, only the friction from the seals and bushings.
So again it doesn't feel like it has eliminated stiction (because the stiction still can be felt), but rather eliminated the preload which used to be typical of air forks.
Let's agree to disagree :thumbsup:bad mechanic said:I don't think preload means what you think it means.
I said it only feels like you've eliminated the stiction because the negative spring allows the fork to activate at a lower force (which the chart shows), and stiction is one of the factors which keep a fork from activating.
