It works on a dyno and I thought it added a benefit to riding.  Obviously I'm super biased though.

I will say- it was a fairly large pain in the ass to get a patent pushed through the right channels at SRAM, so that effort should show we thought it was a good idea.  

Isn't this something similar to MRP's Ramp Control? An adjustable bleeder into a secondary chamber, but more restrictive in one way than the other.

Sounds similar to the Cone Valve dampers that WP and DVO use.

"The main feature here is a cone valve that acts as a blow-off on hard impacts, without affecting the regular damping circuits. That valve can be adjusted externally via the HSC damping, with independent LSC and rebound accessible externally. This isn't necessarily a radical departure from typical fork/shock technologies, but could help keep the ride height high in the travel without sacrificing small bump and large compression performance."

I believe the Wp cone valve is for impacts/compression blow off. Not rebound changes. but either way I think almost all the moto guys (KTM) were like ahh, NO. Unsure what it's gonna do on large impacts.

I think the Cone Valve forks are pretty ubiquitous and popular in the moto scene. The one that they're iffy about is the TRAX rear shock, if I'm not mistaken.

The wiffer is only in the air spring.  Cone valves are in the damper.  Maybe chasing the same performance or ride feel.


Yes very similar to ramp control, but used for fairly different reasons

As a heavier rider who also runs high air pressure and low damping I certainly hope to see the wiffer make it into production!

I feel obliged to point out that pinkbike has an article about SRAM patenting an air based high speed rebound damper.... I've always been skeptical due to how much air A) compresses and b) heats up but interested to hear more informed opinions...

Didn't Noleen have some sort of air damper back in the K2 days? About the amount of time ago a patent might expire? I may be completely wrong on that as my understanding of suspension at that time was pretty limited. 

i don't recall an air damper, but that was around the time i just started getting into mtb.  i do remember reading about their smart shock, which IIRC was some kind of electronic controlled damping.

RE: air only - Total Air Cartridges were a thing for Judy's and the like BITD.  Air spring/damper combo to replace the elastomers and failure prone oil cartridge with a failure prone all air setup.  MRP owns the IP now I believe.

Yes, this reminds me of looking at adds in the back of mountain bike action in 1999 beside a picture of a discount GT lobo.

Since we are all on the suspension side, Diaz just released a "lower runt"

https://diazsuspensiondesign.com/the-lower-runt

I don't how it works, if its similar to what others said above or what, but I'd assume it works good since every Runt upper I've added has been a nice addition to the forks I've had in past (36, Pike).

Dammit! I have a model of a similar get up ready to go once our lathe is rebuilt! Glad to see another idea I had a year plus ago makes it to market!

2nd gen Halson Inversion had pneumatic damping as well

Total Air was a brand in our portfolio – those were made here in our facility. Eko Sport / Mountain Racing Products is our legal name, and we own and produce MRP, Kreitler Rollers, and Power Grips pedals. We also had/used the White Brothers, Tamer (seatposts) and Total Air brands previously, but no longer produce products with those names. We brought all of our suspension line under the MRP brand name in 2013 (discontinued White Brothers). I'm not sure when Total Air ended, but it was before I came on board (2010). 👍

Woof.

I put a set of those in my Manitou 2 in, '95 maybe? While better than the elastomers that came stock I realized how bad they were when I put a Marzocchi Bomber Z2 on my bike!

Not sure if they have been posted here and maybe not tech rumors since the renderings are on their site since a while but does anyone has any information about them to share or refer me to another forum/site?

Well I think the idea is that we would retire the tech and innovations forum after 1000. You old guys can walk these green-ish pastures and comment how you remember when tubeless came out. Or how crazy the idea of 27.5 was when it was released. You retire, your home retires with you Smile


Us young bucks can start a new forum. So yall can sleep well. /s

One thing you won't hear me go on about is how much better things were "back in the day"... Simpler, yes.. But, better? You're gonna have a hard time selling me on that. Maybe somethings have hit a bit of overkill involving electronics.. Yes, it's cool if you want it, but there are some great mechanical drivetrains now.. Suspension designs that actually work.. I guess that even though I'm in the 50+ club, I'm still a bike geek and I've been lucky enough to see some much of the MTB time line and ride a good number of them.. Can't wait to see what's next...
