[Closed] Are rock shox air pressures waay off?

I put 10psi more in my sektor than the guide otherwise it dives on steep stuff. The lyrik usually need 10psi more per kg than a sektor I'm your weight and I run 95psi

Are yours dpa?

Mine have always been miles off. Spring rates too.

Not exactly sure what I set mine at but I'm around 74kg and think I may have it about 60-ish psi on my Lyriks (but that's Solo Air RC2 DH) for 30%. At 170mm.

But ignore what they or any guide says. Set sag yourself visually. Far more accurate. And set it to what feels right. 30% isn't always what you want, or rather you want it so it will just about get to max travel for the ride but not bottom out. So hitting big drops and soaking up that travel, less sag, but a general trail ride, more sag. If you're only going through half the travel in the ride, it's not right 😉

How much rebound

They're only a guide and actual pressure will depend on stuff like how far forward or back your centre of gravity is.

Most stated pressures are a bit out, set on the sag and then dail to taste and other damping settings is best bet.

30% sag is way too much.

My two pence -

Rear shocks, yea you want to stick to the recommended sag to reap the rewards of sitting in the correct position in the shock stroke to yield where the manufacturer intends the anti-squat to be optimised.

Forks, do what feels right, harder the better. Nothing worse than being pitched back and forth on anything steep cos you've got your forks too soft. Rather keep my front end up too to keep things slack. Also 160mm is in the xc mincecore "all mountain" "freeride" range of bikes, you want to retain some form of monoverability, that's the point in them.

Basically 30% sag on a 160mm bike is every kind of wrong. Also if you're not running into bottom out problems with that much sag on that kind of bike, you're not riding it hard enough, carrying around pointless weight that is only further hindering you riding the bike properly.

Dean sounds like bollocks that. Expand and explain, what sag should I run?

Every fork and shock is different in how the damping works so sag is only the first stage of a units setup, different riders setup (stem length, bar width, frame size etc etc etc) will have affect of how the forks and shock work and are setup, there really are no set in stone rules on setup of suspension (although full off rebound (full fast is generally a pretty bad idea 😉 ) being shock [i] absorbers [/i] not pogo sticks regardless of how 'active' you like the bike to feel 😉

30% sag is 30% sag, whatever the forks. Works fine depending what and how you are riding and your tastes. It's an All Mountain bike also, so doesn't always have to be going crazy downhill and big drops all the time. e.g. If I was to ride Whites Level at Afan, inc the so called "black", 30% would be fine and would hit the max at speed (and did on the old descent, sadly gone now). Ride Stiniog however and it's another matter. 30% would be too soft.

But then we're talking Lyriks with stuff like Mission Control, so there's another game there with the settings.

deadkenny - just putting this out there -

So when you're riding smoother stuff and you get away with running more sag, what advantages are you getting?

I can't think of any, can think of a few disadvantages though -

.worse pedalling
.worse at jumping/manualling etc
.less sensitive to shifts in load distribution (what is responsible for your grip) (think race car)
.less speed generation through pumping

Then, when you're riding rougher stuff and taking bigger hits, you're then making the suspension harder, advantages?

.better pedalling
.better at jumping manualling etc
.more sensitive to shifts in load distribution, finer control of grip
.Better at speed generation through pumping

Disadvantages

.Doesn't carry as much speed though the rough (can be counteracted with pumping)
.rider fatigue

It sort of summarises where im coming from with running stuff firmer rather than softer.

Plus the whole thing where people who are rapid generally run stuff harder.

The fastest setup is the hardest the rider can get away with whilst still being comfortable and in control.

Also, for various reasons that I view as reasonable, it's better to er on the side where the spring deals with most, the damper assists, the spring should keep everything propped up. Softer spring and more damping isn't so good.

SAG on forks, do what feels right and er on the side of firmer (think of the impact on geo too).

I agree that 30% is often way too much sag, I guess it does depend on the fork but my Sektor Solo Air and Boxxer RC both feel much better sitting around 15-20%, with this setup i maybe use at least 75% of travel most rides and full travel only if there are drops involved which i feel is right.

OP, yes, they make my bikes effectively rigid.

Given that I don't pedal like a pigeon on a forced march the compliance of soft forks gets me over chattery ground faster than a more 'pedally' setting.
