The first multifilament strings were designed and produced in France, which helped establish Tecnifibre as the industry leader in stringing. These squash strings are manufactured with specificities tied to the requirements of squash and cannot be strung on tennis rackets. Thanks to the assembly of many hundreds of microfilaments, impregnated in liquid polyurethane, Tecnifibre offers players the potential to improve in power and performance. The particularity of this range is to offer a substantial flexibility, in particular in case of off-centre shots and on parallels giving a very strong return.
