Vorsprung Secus air spring upgrade kit - Fox and RockShoxFor the first time, we created an air spring with a truly better spring rate, everywhere in the travel, than a coil. The Secus upgrade delivers the first and only air spring system to really come indistinguishably close to the linear spring rate of a coil fork for the entire first 2 3rds of its travel, with the advantage of a gentle end stroke progression to prevent bottoming without the wall of force harshness that excessively progressive springs
For the first time, we created an air spring with a truly better spring rate, everywhere in the travel, than a coil. The Secus upgrade delivers the first and only air spring system to really come indistinguishably close to the linear spring rate of a coil fork for the entire first 2/3rds of its travel, with the advantage of a gentle end stroke progression to prevent bottoming without the “wall of force” harshness that excessively progressive springs create.
Secus Advantages:
An enlarged negative air spring chamber delivers a soft, supple initial stroke for ultimate small bump compliance (yes, even compared to the Luftkappe)
Proprietary Midstroke Support Valve improves predictability and support beyond the sag point
Reduced lower leg pneumatic ramp means better scalability of the air spring, particularly for light riders who previously struggled to use full travel
Plush and predictable like a coil, bottomless like an air spring
Allows full use of travel in both directions - fully extends to topout without any quibbles (including on Debonair B1 air springs) and fully compresses without excessive ramp
Allows more lower leg bath oil to be used for superior lubrication
Considerably lighter than coil conversions - adds approximately 130g
Simple setup - inflate fork, bounce on it a few times, press MSV charge button, go ride
Compatible with OEM volume spacers for end-stroke progression adjustment
Compatible with other aftermarket top-cap systems such as DSD Runt and MRP Ramp Control
Lower compression ratios mean a more consistent spring rate
Transferrable between any Secus-compatible forks with only a footstud to change at most
Three Stages of Control
By independently optimising the beginning, middle and end portions of the stroke, the Secus gives you the linear-to-progressive spring rate that coil springs and traditional air springs alike wish they had.
Initial stroke - enlarged negative air spring chamber delivers a soft, supple initial stroke for ultimate small bump compliance
Midstroke - where traditional air spring rates drop off in the midstroke, our proprietary Midstroke Support Valve technology boosts the midstroke spring rate to maintain linearity, for support, predictability, ride height and compliance
End stroke - enlarged lower leg volume reduces overall progression even at higher pressures and allows for a wider range of end-stroke ramp options to be utilised with standard fork volume spacers.

Love this entire skincare line
We love this product! I have a teenage daughter who uses it and absolutely raves about it. We use the entire line, including the facial cleanser, toner, and more. Everything about these products has been great—effective, gentle, and high quality. Highly recommend!

Works great, just no different from any other pimple patch on the market
These pimple patches by Thayers are made from 100% hydrocolloid and definitely work in terms of helping speed up the pimple healing process. These pimple patches work best when your pimple is ripe enough. If you stick these pimple patches on when your pimples are not ripe enough yet, they will not do anything, and it would be a waste of a pimple sticker. You know when your pimple is ripe when it comes to a head and has that little white spot. When it's ripe, I would stick this pimple patch overnight and typically by the time I wake up, the pimple patch will have absorbed all the gunk from my pimple. You will know that it worked if you see your pimple patch turn white. Sometimes it might take an extra night for the gunk to come out. When you stick these pimple patches on, make sure your face is freshly washed without any face products or else they won't stick as well. Given what the Thayers brand is known for (natural remedies and herbal extracts), I would think that they would infuse some natural ingredients into this pimple patch to help speed up the healing process even more. But to my disappointment, they did not add any additional active ingredient to this pimple patch despite what their brand stands for so I took off a star.

Great for my teen
We love Thayers everything. They work so great and they truly are invisible. My daughter can wear them to school and not even realize they’re on her face.

A MUST Buy for your TEEN.
Helping my son so much - these work within a couple of hours to flatten ouchie whiteheads. My 14 years old son is so grateful!
There’s 2 sizes, 22 patches, and they truly are “invisible” like the box says.
These have been working so well (better than any other brand - and we’ve tried them all) and the price is the cheapest. We Love THAYERS brand now - lifetime user here for sure.
