Should I consider a Corset if I already have an Evol sleeve? Posted on 4 Feb 12:25 , 12 comments
Fox's Evol sleeve is visually similar to our Corset air can, and based on the same concept. However, the Corset is still a big improvement over the Evol. Here's what the differences measure up as.
It's immediately visible there that while the Evol is an improvement over the old style Fox sleeves, the Corset's initial spring rate is way lower than that of the Evol. How much though? Quite a lot - roughly half, even with enough pressure in there to have a considerably firmer mid and end stroke.
For the substantial majority of leverage rates, including but certainly not limited to VPP, the Corset offers a marked improvement in performance over the Evol sleeves. There are a few bikes out there though that should stick with the Evol or old style cans, such as the Norco Range - these are extremely progressive and require too much sag with the Corset. The lower sag & lower progressivity of the Evol sleeve works better on these, and the old style cans work well too, though ideally a coil shock is best suited to very progressive frames. The same applies to other bikes that are extremely progressive - in these cases you can expect better results with a coil shock than any air shock.
If you're not sure whether or not a Corset is suitable for your bike, shoot us an email and we'll discuss what options will work best for you.

Hi Steve. Thank you very much for sharing this air-spring graphs with us, it is not easy to find this data among bicycle suspension manufacturers. Have you built your own measuring device? At what speeds did you test these shocks? Your graphs are pretty usefull for my front suspension project, that’s why I want to express my gratitude to you/your team for publishing this data.
I digitized your graphs back into raw data in .CSV using https://apps.automeris.io/wpd/ in order to use them as definition for custom shock absorber in Linkage software. Many thanks ;-).

To whom it may concern. I’m Fabrizio and I’m working at the center for Aerospace Research (CfAR) in collaboration with University of Victoria. I’m writing to you to ask if you have some test rig to obtain the stiffness (K) and damping © coefficients from dampers. We would like to have those data cause we are using a shock absorber for bike applications in the suspension system of a landing gear for a small aircraft. If you can do this job for us it would be fantastic!

hi there, i own a Scott Spark RC WC with fox NUDE Twinlock with the NUDE system. is mostly used for XC marathon and stage races, do you think i could get some help form the corset (comfort wise)

Would this be worthwhile for a 2016 Remedy, with Evol Re:aktiv rear shock?

I have a yeti sb45 I have a fox float x on it at the moment. Did swap it out for a DVO Topaz which was amazing however due to fitment issues have removed Dvo and gone back to fox float x
Not happy with the overall feel of the shock will volume spacers and corset change the overall feel of the shock
Please help

Hello,
I have a 2015 Pivot Mach 6 with float x and evol can. To get the plushness I want on the down hill I have to set the sag slightly beyond what is recommend by Pivot in downhill mode but also flip the lever into trail mode to firm it up to climb. I weigh 185 (riding weight) and use no spacers in the shock. When descending, I still get chatter in the upper part of the stroke. I have done plenty of testing with the rebound and compression to tune this out however it still seems harsh. Would your can possibly help?

Hey there, My name is Raa. I was interested in replacing my kashima EVOL SV air sleeve to a normal SV air sleeve. I weigh apporx 240lbs in full ride gear and have to air my shock up to about 325 psi. I’m not really happy with its stiffness, even with a 0.2 (largest allowed) volume spacer. I am wondering if going to an SV sleeve will allow me to run less PSI to achieve a 25% sag range and feel a little more plush. This shock is a 7.825×2.0 2016 fox float factory dps on a giant trance. I see you sell an aftermarket air sleeve. Would this be along the lines of what I hope to achieve? Am I in the right mindset? It seems as though your sleeve is similar to the evol sleeve that i currently have.
If I do change out the air sleeve, Will any valving need to be adjusted?
Thank you.

I was about to upgrade my 2015 Fox Float X by buying an EVOL can, but I think this article may have changed my mind. I have a 2015 Pivot Mach 6 though, which is pretty progressive. What are your thoughts on the Corset on the Mach 6? Thanks!

Hi there,
My bike is a Devinci Troy 2014. Is a corset sleeve usefull for my bike?
Best regards

hi there,
i have a 2016 norco range A7.2 running the first model of the fox float x with kashima coating. size is 8.5 × 2.5. i have been looking at getting the evol sleeve or the corset but unsure which would be best. i find the current set up is good but the intial part the shock is not the smoothest and i am still getting very close to bottoming out on every ride even with the bigget volume spacer and a bit more air than recommended in the shock. i was wondering if the corset would help with the initial stroke and with the resistence to bottom out?
also i have the yari fork. i have been looking into whether or not it is worth getting the lufkappe upgrade? a lot of people have said it wont really help the fell of the fork and to make it worth while i should get the charger damper also? i havent seen many reviews regarding the fork upgrade for a yari so is there any information on this which you could help me make a decision?
thanks Jamie

I installed a Corset Sleeve on DRCV shock thats on my 2013 Slash 9 and it made a major difference in my opinion. I have a 2014 Remedy and a Fuel EX, I’m considering the upgrade for these also. Would like recommend it for both of these, DRCV on these. If so which one would make the most difference? I’m only doing one at a time so I’m not sure which to do first.
Thanks.
