This is called the Tecnifibre Carboflex 135 S:

Head Size: Large (500 sq cm)
String Pattern: 14 x 18
Strung with: Tecnifibre 305+ 1.2
There’s never been a Carboflex 135 before, to my knowledge. I think this is probably replacing the Tecnifibre Carboflex 140, which was obviously 5 grams heavier.
So, if this racket has never existed before, why did they feel like they needed to stick an “S” on it? Perhaps you will be Superman if you play with this, but more likely, it’s because the Tecnifibre Carboflex 125 S and Tecnifibre Carboflex 130 S both have Ss, and they didn’t want this racket to feel Sad.
