If we learning anything from our Suspension Setup Series last year, it’s that tinkering is good and that more tinkering can be even better. Once you move beyond the basics of air pressure and knob fiddling, there’s air volume adjustments.
We’ve upgraded our own shocks in both directions, using volume spacers to reduce it to help the rear end keep up with a bigger-than-stock fork, and adding an oversized can to improve overall “bouyancy” to an otherwise firm XC bike. The latter is exactly what the new Vorsprung Corset air sleeve upgrades are offering for Fox Shocks. Available for a wide range of models and sizes, they increase the air volume, which gives the shocks a bit less resistance to initial movement and a cushier mid stroke. The result should be more supple performance on the small stuff and smoother action throughout the middle of its movement…
The Corset has been in development for two years, tested throughout Whistler’s amazingly diverse bike park and surrounding trails as well as on the EWS (Enduro World Series) races. It’s made in Canada and retails for $150 CAD.
Full Specs (from Vorsprung) are:
What the Corset offers:

– No more wallowy midstroke
– Adjustable ending-stroke ramp using volume spacers (sold separately)
