Rock Shox Lyrik - huge brake dive
dnl
Posts: 5
Hi!
I recently purchased a Canyon Strive enduro bike w a 2011 Lyrik RC2DH 2-Step fork (w air spring, but as far as i know it is not the same as Solo Air - or is it?)
I've been on a couple of rides, and i think i got the air pressure nice and comfortable on the fork, and im still getting a huge brake dive. If i'm sitting in the saddle at about medium cruizing speed (say 20 km/h), and i pull hard on the brakes (rear weel does not being lifted in the air) the fork dives in about 75%of the travel. If i am slowle ascending on a steep section the front end dives so deep that i loose most of the control compared to my old non air-sprung fork.
Also :
- increasing low speed damping does not alter the experienced brake dive. Although i must say that all my previous forks have not had compression damping), and i barely feel any difference when playing with the high-speed and the low-speed dials. Could that be possibly related to oil levels?
- when i release air pressure from the fork leg, the oil that is supposed to be injected into the lower leg is seeping out through the air valve. Is that normal?
Oil levels have been checked, all is up to spec.
Is this break-dice a tweaking-setup kind of thing, or can we generally declare that bigger brake dive is a characteristic of air springs?
Anxiuosly waiting your opinions!!!

Sounds like you need more air - what sag do you have?I don't do smileys.

Tried the FAQ's?0

Yes, i've been trying adding more air.
I started with the recommended setting, and increased pressure in many steps: small bump sensitivity is decreasing as i add the pressure, but the dive is (though less) but still very significant...

Forget the recommended settings - what sag do you have?
Looks like a common problem

Set the sag then brake dive should be controlled by the damper.
How many clicks of Low Speed Compression and High Speed Compression are you currently using?
Turning the silver low speed dial clockwise should reduce dive (might not be noticeable by pushing on the bars turn it up and ride it to see the effect.)
Sram have 2 tuning guides for the Mission Control damper but ignore the flood gate, if you have the DH version you wont have it.

Is there any/enough oil in the damper. or if that's fine perhaps you'll need to tune the oil weight changing to a heavier weight shock oil (more viscous) will give more damping.Mountain: Orange Patriot FR, SubZero & Evo2LE.

The air spring is usually better at controlling brake dive than coil I find because its more progressive.
You need to set the sag, but forgetting the recomended values. Set the fork up so you have about 20 - 25% sag

Also, have you set up your rear shock? It could be rebounding too quickly and forcing the front down on descents?0
