Vorsprung Suspension is excited to announce the release of its new Corset air sleeves for Fox air shocks. After more than two years of development, the Vorsprung Corset air sleeves deliver coil-like feel and performance with air spring weight and tunability. This is achieved by producing far less initial resistance than a standard Fox air sleeve, coupled with vastly superior mid stroke support to eliminate that wallowy feel and initial harshness. Long story short, the Corset's spring curve is now much more linear in the first half of the stroke - and far closer to that of a coil shock.
Designed and tested in Whistler, BC, including quietly racing prototypes in the EWS, the Corset is proudly made in Canada. What the Corset offers:
- Coil spring feel, air spring weight
- Less initial resistance means better traction and small bump compliance
- More mid-stroke support
- Livelier, more predictable feel
- Better big-hit control
- No more preloaded initial feeling
- No more wallowy midstroke
- Adjustable ending-stroke ramp using volume spacers (sold separately)
- Compatible with standard Fox air sleeve seals
- Easy to install - kit includes air shaft seals
Compatibility and Models:Fox Float R, RP, RP2, RP23, RP3, Triad (all years)

- No more wallowy midstroke
sounds like solution to all my life problems...
Did somebody mention they look awsome?
Their CTD forks (namely the '13's): that's a whole other story.
I am intrigued by this and I too am going to have to try it.
Also why he had to try and sue SRAM?
Anyone dumb enough to try and call out companies worth close to billions of dollars on things that he thinks they're doing wrong, I don't consider to be too intelligent.
Steve is one of the most passionate and capable engineers I've met, with in my honest opinion, a level of attention to technical detail that would be beneficial (read: offer improvement) in the highest end companies. It just so happens that he chose to start his own business instead of working for someone so that he can do things 100% his way. If he releases a product, I can almost guarantee that it a) does what it claims, and b) isn't a marketing stunt.
Seems to be the same principle. Maybe an explanation to Steve sueing SRAM ?
We didn't see anymore pictures of float X with the same "corset" or "Debonnair" style air sleeve.
Does Vorsprung have patented their sleeve ?
Does this explain the animosity of fox and SRAM representative on Steve ?
1. The air pressure you run scales everything up or down. Units were provided on the spring rate graph simply to illustrate the difference in initial spring rate that you can see between stock & Corset sleeves on a numerical level that people can relate to.
2. There are several stroke lengths that this could apply to, so saying force is Y at X travel is a bit pointless given that it'd just be at an arbitrary pressure and could be any of several actual positions!
I get the linear discussion and all, but I don't really understand what this is supposed to do different if it's simply an empty sleeve and the damping and everything else on the shock are the same. I'd like to believe in your product but I'd like a little more info on what it does that changes thing in the operation (not just results).
Thanks
In layman terms, if you compare a coil shock and air shock on the same frame, you'll notice the air shock is much harder to move at the start (amongst a host of other issues), which is a result of the non-linearity of the air spring compared to a coil spring. It results in poorer traction and bump absorption as well as wallowing in the midstroke compared to a linear spring. What Vorsprung's product does is corrects this problem at the spring level. The damper is a different level and you can't correct this problem with damping, which is why they have redesigned the air spring (which is not actually a simple empty sleeve, and has two chambers that have varying pressures and volumes as the shock moves - thus is fairly complex in its behaviour).

not a fan of RS stuff, different strokes for different folks.
This looks like a fresh idea to help all of us with DRCV's, without spending the cash on the Debonair. Thanks @VorsprungSuspension !
edit:
my b, that is with a CCDB air, although i believe i have seen them with coil shocks.
Package shouldn't take too long to make it down to the north shore, right....
Great to see this available. Almost makes me want a Fox shock.
Almost.
"25% higher pressure is a starting point and will depend on frames. Some people only run 10% more, some people are as much as 30% higher "
Have you any 250 pound+ AM/Trail test pilots?
I am wondering about max air pressures.
I am currently trying and enjoying a coil shock
After getting terrible ride quality and mileage out
Of a few different air shocks.
I do have a DHX 5.0 air I would try strapping a Corset on if it's a go for big bros.
Saving up for a fox 34 fork revamp too I think,looks awesome!
Thanks
I have bike with a DRCV shock, and a spare shock lying around, and am interested in trying this out....Keep up the good work.
@turtlesauce2000, yes it does. We tried to make it as simple and user-friendly as possible, so it is compatible with a standard Fox seal kit for serviceability.
Plus I'm pretty sure new Float X protos have a similar can (like the Debonair).
Would this work for the spring curve of a Rocky Mtn Altitude?
Seriously, and not hating, I am curious.
Am I right in thinking that this will basically mean that the rear will track much better as the top part of the travel is more active? Bit of a suspension noob to be honest...
"Custom FOX Float CTD Factory w/ AUTOSAG and Boost Valve, Kashima coating, Climb, Trail, Descend settings and reb adj., 195x51mm"
Which if any of the cans would be the right one for me to get? 195mm is approx. 7.68 inches? which doesn't seem to match any of the cans listed.
Thanks in advance. Hope I can buy one.

Which model of the Corset is the appropriate one for my bike?
Hi! Which one should I be purchasing for my 2014 Stumpy Evo 26"? The Specialized website lists my shock as a custom Fox Float.

"Hi,
Thanks for ordering a Corset air sleeve from us! However, unfortunately (or fortunately?) we've received a MUCH greater volume of orders than we had anticipated in this time frame, and we're struggling to get them out the door fast enough. We're doing everything we can to ship them ASAP, but at the moment unless you have already received a shipment notification (you may have - obviously this is a generic email), it is most likely that your order will be shipped some time next week. If for any reason this is unacceptable, please let me know and we can cancel & refund your order immediately, otherwise please accept my apologies for the delay!
For the same reason, I am doing my best to respond to everyone's queries but if you've emailed me with follow-up questions, please be patient and I'll get to you as soon as I can!
thanks,
Steve"
It would just be nice to see markers or grid lines to better focus us on how far along in the displacement the inflection points and other interesting elements of the curve are.
so let me get this right, if i'm skipping down through a rock garden the back end will be way more inclined to get up out of the way rather than shove the rear of the bike up ?

Seems like negative spring pressure has been put into the forefront last 2 years of air spring development.
Nice work, would love to try this out.
How is the negative spring pressure set/recharged?
I hope there is a pisser port type "thing" like Fox and RS.....
Very good work. Have you tested one on a float x on a transition covert at all? and what sort of results did you get?
How did you find it on the covert? seriously considering getting one for the float x on mine

Even if it does work, is it advisable to work on a Brain shock at home? I've been told Brain shocks have to go back to the factory when work is needed.
Seriously though, gtrguy is on the money
@VorsprungSuspension Can I custom order one that says "bigger and blacker" on the side?
