Progressive Air Can ( Meg-Neg ) Assembly for Deluxe C1/ Super Deluxe C1 (2023+) please check compatibility before buying, this does NOT fit the older Super Deluxe A / B designation Air Shocks.
Suitable for 57.5mm-65mm shocks
The Progressive air can offers a greater negative air volume, making the negative spring effective for longer throughout the travel. Similar to the MegNeg air can, the Progressive air can makes it easier to get into the travel right off the bat. The increased negative volume also makes the end of the spring curve ramp up quickly, so it's harder to bottom out. We suggest pairing a Progressive can with a linear leverage rate frame to bolster end-stroke support and prevent bottoming out.
The chart below shows the air spring curves for the Linear and Progressive air cans. You can see that with the Linear air can, it takes more force to get into the travel but offers more mid-stroke support and less effort to reach bottom out. The Progressive curve shows that it takes less force to get into the travel, but the curve ramps up increasingly as it moves through the stroke, making it much more difficult to reach bottom out.
