I just came across this rubber from 729 that apparently is made in Germany. Is it from ESN?? Its fairly cheap for a ESN rubber. Anybody know about this?

Made in Germany = ESN. "We" only have this one factory.

As for DERWIND rubbers, Rayhe and Stolz can be bought for 19,90 at one German shop, and they have a new one called Stellar which is a faster version of Rayhe, that goes for 32,90.

At first thought, I thought the sponge looks a bit like Rakza 7. Does it have similar speed and spin as Rakza 7?

 

[Airoc]

I haven´t played either Stolz or Rayhe.

Stolz is described as soft-ish (40 to 42 European hardness) and easy to play, while Rayhe is a nominal 45 (but apparantly feels harder).

Is that a hybrid with tacky rubber and tensor sponge?

Doesn't look tacky. It looks like a pretty standard ESN rubber such as Rakza

It took 15 seconds to find.

The label says BIOS and not Tensor. What is the difference?

 

[PingBirdPong]

Nowhere on the packaging does it say “729” or “friendship”. Maybe the sellers just put 729 friendship in the description so it will show up in more searches.

Bios is a particular tensor system.

Bios is a particular tensor system.

Is it considered the 2nd tier Tensor system?? For example, I notice Gold Arc 8 says Tensor but Gold Arc 5 says Bios.

It's not 2nd tier, just one of the many ESN tensor systems.

If I remember right, the Evolution rubbers are Bios, If you look up Tibhar catalogs online, I think they explain what Bios brings to the table.

Nope. It is an environment friendly rubber material free of VOC fumes.

 

[mocker88]

It was a collaboration between the German company Derwind and 729. 729 wanted to try to make a better non-tacky rubber with German sponge and produced Stolz & Rayhe, but the project was discontinued as the cost became too high.
