From 2020 Q1, (starting with the TK-F C new color repaint) all Taiwanese made rackets will be updated to a lighter weight, the new designed rear cover. Advantages: 1. Weight: 40% lighter than the old rear cover, only 2.4g in weight. It can make the racket have more space to adjust the weight parameters, and adjust the more precise physical properties: 2. Material: To strengthen the cap, we introduced ABS plastic, ABS is a kind of ternary copolymer, composed of three different characteristics of materials. It has excellent dimensional stability, more than 2 times higher than the strength of ordinary plastics, can maintain good toughness under such a floor design. (Google translated, i edited a bit.)
