Very well. The sun finally came out, but every trail is currently underwater. I may have some good pictures soon. I am reshimming the fork damper to match the rear shock and remove the platform over the next few days.

Field Test: Yeti SB130
@DrPete: most bikes aren’t designed with the shortest chainstays possible. 436 felt neither stable nor playful on my first 29er frame, but 440 makes for a beast on loose climbs. Shorter isn’t always better.

5 Surprisingly Nice Catalogue Frames - Taipei Cycle Show 2018
Number 1 is 130 mm travel, 67 degree headtube, 165 x 45 trunnion, ~75.25 effective seattube angle in size medium (70 actual), 440 reach medium, 95 mm headtube, 440 chainstays, 180 mm post mount, 148 x 12 rear, threaded bb. I have one. It is roughly $550 plus shipping. It is awesome. The edge python is something promance reworked to use a larger headtube and heavier layup. I had the original, and it didn’t last long. It was nice and stiff while it lasted.

All the Adjustments: Formula Introduces the Selva R Fork
@Socket: the gamma value is the ratio of specific heats at constant pressure and volume... Which is part of the work and internal energy system. Which sums to 0. Which is not speed dependent. Regardless of whether the resistance is zero for an instant or not, the work done and resulting pressure are the same. If somehow airsprings got harder the faster they are hit at all times, then the work done would be less than the change in pressure and you would have invented a perpetual motion machine.

@Socket: that is an incorrect analogy. Neopos is foam. Foam has damping properties. The faster it is hit, the harder it is to compress. Air springs behave oppositely all the way to the speed of sound, where the air sprig has no support.

@rideformula: you have some words mixed up. Dampening, or damper curve, not progression curve. I would suggest consulting a technical writer for your adverts, because this reads like garbage. Formula products rock by the way. Any plans for an air shock to match?

Air springs are speed sensitive. The faster they are hit, the lower the spring rate. A speed sensitive damper will certainly help with the progression of the air spring. By like 2 percent most of the time.
