Need information about the wood structures of the Gewo Power Series

[bwstt49]

Greetings friends
I have questions about the structures of the Gewo Power Series.
There are 3 version
1. Gewo Power Allround (https://www.megaspin.net/store/default.asp?pid=gewo-power-allround)
2. Gewo Power Offense (https://www.megaspin.net/store/default.asp?pid=gewo-power-offense)
3. Gewo Power Carbon (https://www.megaspin.net/store/default.asp?pid=gewo-power-carbon)
I can't find any information about these 3 models on Gewo's official sites, So please let me know what these blades are composed of.

I sincerely appreciate your help.
