Hi
Was thinking.
At every hit, the tire is the first to get hit. Than the suspension.
But...
The tire have no rebound settings. Its like a spring. And every hit will couse it to rebound fast and make the suspension get a second high speed compression from it.
So every hit is 2 compressions.

What do you think?

 

[vivisectxi]

yeah, lots of complexity to the system dynamics for sure. it's interesting to watch the slowmo hucks to flat:

suspension movement is is rarely smoothly linear, and there's certainly bouncing going on with tire rebound.

not that i *really* care to try to wrap my head around such things. my bike goes squishy-squish, it's all good.

This is why its a good idea to keep tire pressures consistent, along with suspension settings. At least thats what I find.

I have some days where it feels like my suspension is acting like garbage, only to realize that I over inflated the tires or something similar.

Inflate your tires with humid air, it is damper.

I inflate my tires at altitude.























Yup. At whatever altitude I happen to be.

Tire case is a rebound adj

if high pivot bikes have a rearward axle path on compression, then on rebound...........wait a minute


















HAI GAIS!!!!!

I usually forget what I am doing by the 2nd hit...

There's a second hit, I always thought hucks to flat were all 1 big "oh $h!t" hit...
I was too busy paying attention to my spine, lol that's how I compression fractured t6 and t7..was a really really epic huck to inverted not flat..

Was epic and badass.

 

[saruti]

I really missed this forum
I know there are tires that are ST and other compounds. But still. Its full of air.
I have an idea of how to fix that... but...
I want to hear more of your input

The agricultural sector is of course wayyyyy ahead of the game:

[Redwood Mulch Chucker]

It is interesting as there are basically two springs in the system, and if you have inserts and are running 18spi like some North Shore Bro then it changes the tire spring effect again as it's then air+pool tube.

@saruti , so what's the fix?

I really want to get some data acquisition stuff just to up the suspension geek level a few magnitudes.

 

[SylentK]

From a wholistic approach. I don't think there's a solid one answer. But I know what you're talking about. Usually, I know if I pull a move and I'm gonna bounce, I prepare for that. It's not really the bikes fault.

And I know from experience, if I adjust suspension for that specific circumstance that the rest of the ride might feel wonky.

Fill your tire completely with Stan’s, two problems solved!

 

[rideit]

*scribbles 'elastomer hubs' on napkin*

I have searched and searched and searched, but I distinctly remember these existing in the late 80’s/early 90’s. IIRC, they advertised 1/4” of ‘travel’, which seems like an awful lot. (Think of your rim going up and down a 1/4“, and what that would do to brake pad setup).
I am sure I read about them in MBA. It was about the same time as the ‘Mountain Tamer Quad’.

Time for a refresh!

Bark and Pinecone have never heard of it so it's a new market in this ever evolving sport!

be sure the smash that like button!

[rideit]

LOL, Sage (Catabriga )left a backpack in my truck once while shuttling, I could smell it from the front seat. I didn’t know how to get it back to him, so I gave it to his dad, weed and all. It reeked.

Wait…is Bark some other scruffy-haired Sage?
Appears so.
Are they with their dog, Cairn?

Answer: Who cares

Bark and Pinecone is fucking gold.

LMAO. Bark and Pincone!

I haven't seen one of their vids in a looooong time. Same with a lot of the similar utubers. Vanlife bro! Naw. I'm good.

I'll just get one of these things (no knot really, but they are just down the interstate from me. Can't justify the cost):

This is why its a good idea to keep tire pressures consistent, along with suspension settings. At least thats what I find.

I have some days where it feels like my suspension is acting like garbage, only to realize that I over inflated the tires or something similar.

Overinflated as in 50 psi or 35 psi?

 

[Lelandjt]

Tire case is a rebound adj

Exactly. It's also compression damping. That's why Double Down and DH casings feel better. The damping (turning motion into heat) is also why they pedal worse, so no free lunch.

 

[SylentK]

so no free lunch.

Yes there is. Right in Grand Junction.

You know, the Lunch Loops. HA

 

[canadmos]

35psi. Come on, 50? I don't have that many preride beers.

a family member had one of these. ~$1/2M and always seemed to be in service. he had planned a round the world trip, but after it breaking in costa rica (a repair that required shipping large parts from the US, over a month lead time, etc), he decided it probably wasn't the best tool for the job & unloaded it. not to mention it physically wouldn't fit lots of places, and being conspicuously $$ isn't a great idea in some zones.

Which reminds me. Are you still on 808 time?

Man, snow here is less than you'd expect. Like Arrowhead and Bachelors Gulch are not open yet. You can use their lifts, but not open to ride. Not sure what's open at Breck. Went to the Beav, even tho we stayed near Vail. Peeps at Vail were reporting super thin conditions. Less than impressive, I'd say. Snow guns still rockin'

 

[OGRipper]

After the second hit I tend to reduce pressures all around.

Yeah, wow. They are fancy. But wow, I guess it's not the "camper" part that is the fault. Moar like the Ford chassis (or whatever engine/chassis) they decided to use?

I pass their company all the time and am like dude, sweet. And then I am like Naw.
