Tecnifibre ATP Razor Code 17 is a firm and durable co-polyester string that rewards full swings with pinpoint accuracy. Our TW playtesters found this one to provide remarkable precision and very easy access to spin. Unlike traditional polyester strings, ATP Razor Code is built with special additives to improve feel. In addition to being a great option for the advanced player, this one has enough all-around playability for the strong intermediate who wants to make the transition to a firmer control string.
