It's not long ago that 150mm bikes were winning world cups. If you "need" more than that, you must ride some interesting terrain.
I have just got a 130mm bike (having not ridden much for 10 years) with a lock out, which helps on climbs. When I get round to it, I will increase the oil height in the forks to make them more progressive at the bottom of the travel, but tbh, they are really soft just now, and I rarely use more than 50% of the travel on a dh as my weight is over the back wheel.

Softening a long travel bike's springrates for 25 miles of bridleway riding?
Really?
so you run with the same suspension settings for sending it down a WC DH track as you would taking part in a 1000mile marathon event?
Simple fact is, the longer your fork, the lower spring rate you can run before you hit the bump stops (F=MA and V = FT) for any given deflection.

Is it bad that my answer would be yes.
I'm doing Afan in the same settings I did the SDW, the same ones I did BPW on
not at all, it's all personal choice!
for me, i'd run way higher pressures for smashing down a DH run at max chat that i would for a 25 mile pootle along a horse rutted bridleway.
And that's really my original point, the longer your fork, the more window you have for setting up differently even if you chose not too 😉
It's probably best I leave you to figure it out yourself.

so long as you enjoy the ride!
Not trolling, but i'd love you to properly explain what i'm missing?
Say you want to change the velocity (v) of an object of mass (m)
As F=MA, and V = FT, a given deltaV can be achieved with either a higher force over a shorter period, or a lower force over a longer period. So, the longer travel you have on your suspension, the softer (lower spring rate) you can run. The end result in the same deltaV but as every force has an equal and opposite fore, a lower force over a longer period is more "comfortable" especially for devices such as pedal and motorbikes where the ultimate ratio of sprung to unsprung mass is characteristically poor.

Which one of those is a WC DH track?
Forget the first year Uni mathematics/physics
Let's go back to your stupid 1000mile on a WC DH bike anology...
Would you really want your suspension cycling through all 200mm on the sort of bumps you find on a bridle way?
No.
Just because you payed £800 for 170mm of suspensionz doesn't mean it's appropriate to set it up to be using it all on every ride.
Blowing through travel too easily is not only horrible. it performs poorly, results in an unstable ride and loss of grip.

Ignoring the fact i have repeatedly said i'm not talking about letting all the air out of your fork, say just moving the sag % about 5 or 10%, ie, if you'd run 25% normally, then 35% sag brings a more comfortable secondary ride frequency without major differences in primary ride frequency (which for something of low mass like an MTB is set more via the damping components (inc. friction) for low velocity damper extensions
Why would it "cycle through it's travel" when there is no inputs from the road surface to force it to do so!
10% more sag is huge.
imputs aren't just from below the bike
No matter how retarded it is. If you genuinely enjoy riding bridleways more while being sagged 35% into a 170mm fork keep doing it.
it's your money.
By the logic in this post everyone should be rolling around on DH bikes as thats all anyone needs. Sag it your if you are on a canal towpath, reduce the sag if you are riding gnar. SICK.
The shrooms are strong in this thread
Sorry!
I thought i had missed some critical fact, as i obviously haven't got a clue what i'm talking about, but it turns out that no, i hadn't, or at least if i have, gwurk is for some reason unable to articulate the issue!
(btw, i spent 3 years as a WRC suspension engineer, during which time we won the championship so i can't be that bad at suspension eh..... 😉
I'm guesing the WRC driver didn't weigh 6x more than their car?
or constantly move from the front to rear and side to side of the car for the duration it's journey to...

I always think your better off using say 90% of your 130mm travel most of the time than lugging round 160mm of travel that you only fully utilise 10% of the time.
No you aren't, that means you have very little left in reserve for either sending it large or making a mistake.
I'd rather run a 160mm stiffer, than drop down a 130mm bike and run it softer. The former is going to be more playful and safer to ride.
Which one of those is a WC DH track?
None, but if i took my bike to the Alps i wouldn't change the settings either.
I dont get the arguemnt between Gwurk and Max, fork settings are personal choice. I have a 160mm Lyrik which I run just over 30% SAG everywhere.
Overbiked or undrbiked, did anyone ever die from being overbiked?
I wouldn't dismiss shorter travel bikes - my Scout is a little hooligan of bike despite only having 125mm of rear wheel travel and being designed to run 33% of sag.
I've had a 160mm travel bike before and it did feel like hard work on the tamer stuff (on the right stuff it was brill though). I ended up going the other way and riding hardtials but have ended up on the Scout and am so far really happy with it.
I tend to run my suspension at 30% sag (my Yari's don't have any tokens in them). Works for me.

I truly don't know how people can run 30 percent sag on forks with no tokens, especially the shorter travel forks which need more tokens. I'd constantly be running the risk of bottoming out and going OTB with a setup like that. 😕 😯

They seem to ramp up big time and don't bottom out constantly. With one token in and the Luftkappe they were just too harsh and I wasn't getting enough travel out of them.
Or I'm just not as rad as you... 🙄

I think it depends on a lot of variables - the air spring curve, the damping curves, your weight and probably most importantly your riding style on the bike. And obviously how fast you're riding and how big you're sending it.
I'll get pretty heavy on the front in the turns, especially flat ones, but as soon as I'm hitting rough stuff I'm loading the bike more through my feet. I don't ride with 30% fork sag because I prefer the firmer feel with a bit less but I've tried it (pre-Luftkappe) and it wasn't disastrous.
And Yaris are known to ramp up way more than Pikes or Lyriks due to the damper design effectively adding a parallel low volume spring to the main air spring.

Yup. Tried them with one token and 20% sag and they were unbelievably harsh. On a normal ride I was struggling to use more than 100mm of travel. Without the token and a tad more sag they’re doing a grand job but I will be getting some coil forks in the new year because they’re just nicer.
