Just a follow up. Last weekend I pulled both my PNW and Tranz X posts out. The PNW post had breather holes while the Tranz did not in the base pieces. I drilled the PNW to 3/32 and made breathers on the Tranz. A few things happened. First, the posts don't wheeze as much as they used to. Makes sense since they now breathe easier. Second, both return a good bit quicker. I didn't do anything to the cartridges, so it seems the larger & added breathers allow the pressure to equalize in the post easier (again, makes sense). Third, both posts stopped leaking out of the dust seal. It took more than a few activations, but eventually they stopped leaving a lube ring around the stanchion. I can't confirm grime isn't getting into the posts, but it seems reasonable that since lube isn't getting pushed out that debris won't be getting sucked in. Given the similarities in architecture between these and the One Up, I wouldn't be surprised if the same mods remedied the same issues. Obviously the warranties are voided, but I feel this may be something that solves design problems that create warranty issues.
Also, the test ride for the Tranz was on a night ride in sub 0 F on my fat bike. It was a bit weird having the post pop up as quick as it does now. Nearly resulted in some discomfort in the posterior.
