Why don't Chinese porous sponges shrink?
Read my answer and you'll know why a chinese porous sponge is nothing more than an hybrid ESN/Jap rubber, that's why many people here uses the H8, H8-80, H3-50 or H3 37°
Exactly, the air cells deflate, less air = less catapult. That's why many people find the old shrunk ESN/Jap rubbers to be slow after 6 months.
Oh that's a bit depressing to find out. I wish I hadn't taken the Presto Speed rubber off the blade then.
Should I put booster on it to try to re-inflate the air cells?

It will not do more to let the rubber on the blade for more time to prevent from this issue: it's a physics issue, as long as there's air in ANYTHING, it will deflate with time: tires, any team sport ball, Nike Air Max sneakers (I got one old pair of those Air Max 90 sneakers that is damn hard now), and the list goes on and on...

I have a Presto Max Spin that shrunk a bit, and I added a couple of layers of the TT REvolution No.3 booster to the sponge, and it got the bounce back and added a bit of soft feeling it din't have before. And it got a bit bigger again. Perhaps it will work the same with your Presto Speed?
Yep. Also confused about what I'm reading here. Any high tension rubber will shrink if you glue it on and subsequently remove it. I always cut my rubber sheets slightly large to avoid this problem. G-1 will absolutely shrink if you peel it off (mine just did this).
Glad to hear I wasn't the only one to experience that. I just peeled and re-glued a Fastarc G1 Red sheet in the relatively new Max thickness. It shrank a little, but seems less than the previous red ones I had in 2.0 mm that shrank a lot. Really liking the Max - feels a little softer, but easier to generate more spin with (for me at least!) especially on serves. I hope it will be as legendarily durable as the super thick G1's. It should be as the sponge composition/top sheet look the same.
I like to also add, it doesn't only shrink after you peel it off.
If you do a very good cut, you an actually notice the edge of the blade getting bigger and bigger (meaning it is shrinking on the blade, and the edge is appearing).
And of course that is time that the effect of the tension is gone.
You peel it off and it looses 1cm or around the side.
Add two layers on booster, and magic. That 1 cm is back.
So where did that 1 cm go?
did not age well
Or you got an old Fastarc, don't you think ?
