I’ve tried even a soft fabric between the vac chamber and the bars but still run into and have the same issue. It seems even just resting against the bars with a cloth in between is enough to ruin it. I’m guessing it has something to do with the tension on the silicone sleeve in this position since it is also pulled tight from the vacuum hold.
This method of PE is by far the most productive for me. Normal extending doesn’t work for me for about 6 different reasons, and vac extending finally solved it and beats hanging for me as well. The issue is that I either need to ensure the sleeves last longer or need a source of sleeves where the cost is as if they’re disposable.
If I’m able to use the same silicone sleeve around the vac chamber 3 times it’s an achievement.
I’ve recently started using some toe guard silicone sleeves but even these aren’t disposable enough and wear out even faster.
Is there any way to buy the silicone sleeves cheaper or to preserve them longer?
(Also going to need more bars soon, I’m at the max it came with but with the vac chamber I’m at the right tension with it exactly at max).
