Wish they’d offer a mullet, but they seem pretty against it. Always wanted a Raaw, but I’m fully drinking the bullet kook-aid.

Looks like that varying the angle of the cone and the cone seat could affect the damping characteristic as well, so it could be tuned in a similar manner to a spool valve, which supposedly is more suitable than a shim stack...

Yeah a spool valve was the other design I thought it was closest to, lots of variation is theoretically possible with it.

Too bad it's patented for all vehicle applications by Multimatic :/

Is the WP Cone not just a larger poppet valve? 

Spool valve would have a sliding surface across opening to seal it. Spool spool movement is not affected by the fluid flow and pressure. The cone is going to be affected by flow and pressure.

The spool valve is affected by pressure (resulting from flow...) just like a cone valve as it's a capped off cylinder with ports in the cylindrical wall with a spring pushing on the capped surface. So when the oil pushes on the capped end surface, the spring gets compressed and moves the valve and thus opens the ports.

The manner the cone valve achieves this is a bit different to what the spool valve does, but the end result is very similar. You can change the spring under the cone or the angle of the cone with a given spring, but both cases will result in different rates of the valve opening under a given pressure. And result in different damping values.

Compared to a poppet valve, once the poppet valve is opened, the damping is more or less controlled only by the size of the ports. With the conical valve as the cone is moving away from the base surface the 'port' is opening up and you get less damping. Which is the same as with spool valves if you have a constant cross section of the port along the length of the valve. Though with spool valves you can play with the shape of the port, which makes it possible to achieve basically anything you want characteristics wise.

Not sure if this is true, but in my mind, a poppet valve is either open or closed. Whereas the cone valve has open and closed positions, but everywhere in between as well based on the oil pressure, backing spring and cone shape?

Yeah a poppet is basically open or closed, but a spool has much more of a variable opening. There are several different variations of a spring-on-plate type of valve that are usually lumped together as "poppets" but in reality are very different. As soon as there is a difference between the flow area the oil can pass through and the surface area the valve, you are able to get very different characteristics than just on or off, depending on how far the plate lifts. So an old float X2 or double barrel (and current CC shocks) base valves are the most like poppets, but the current X2 is not.

Push also uses a "shim-less" design for the high speed compression valve of their HC97 damper.

Whats hiding under the tape on the gearbox bike?

think its a bit of carbon?

maybe some trellised CNC work like the swingarm?

I think it's there just to close off the truss to prevent dirt build up.

My understanding it is just covers for dirt because the bike is made from I-beams, which have large spaces for dirt to accumulate.

 

I've seen it in blue as well as gray/white

All that secrecy, and the button on the handlebar...makes me think this regular looking Öhlins shock is just a red herring for the photogs... (or there is something SUPER interesting going on with the linkage itself, like the pivot points moving with a servo motor or something like that...or Finn doesn't have the same shock that Loic does...)...

That was my initial thought, but I cant see any witness marks on the tape from any lattice structure behind it.  an open "I" beam structure wouldnt hold tape very well, as there wouldnt be much to stick to.

And youd think if they were taping it up for racing, theyd be re-thinking the idea as a (w)hole...

Yeah, looked like blue painters tape, now it looks like white hockey tape.

Hard to keep something stuck to that small space if it was an open "I" beam, wouldnt be much to stick it to, and I figure youd see imprints of an open lattice work if it was that. 

Who knows, maybe just a pop of colour

I'm glad we mold the logo into our product, makes the Sharpie shenanigans less effective.

5seconds of Dremel work would take care of that.

I hear what you're saying, but go take a look at the injection-molded backside of Richie's bashguard that you can see in the non-drive pic. If you dremeled off enough material to get rid of the MRP logo you would have dremeled away the entire bashguard in the process. I think that's what Noah is referring to.

Looks like a 38mm Marzocchi is going to be released during Rampage.

Their website seems to suggest the Shiver name could be coming back.

Judging by the caption they'll be calling it the Super T or something along those lines. 

"Rampage is here and something Super is roaming the desert. "

Ehm, those lowers are completely different? Unlike previous marzocchi forks that used older fox lowers.

That would be suitable for electrical tape treatment which would also double up as mud buildup prevention nicely.
