Solinco Tour Bite is one of those tennis strings that serious players swear by. The 17 gauge (1.20mm) is that perfect balance - not so thin it breaks quickly, but thin enough to provide great feel and spin potential. As a polyester string, it offers excellent control and durability, which is why so many competitive players use it. The Tour Bite specifically has this sharp, square-shaped filament that really bites into the ball for insane spin generation. You get two full sets in the package, which is perfect if you're stringing multiple racquets or want a backup. The tension maintenance is solid for a poly string, meaning it doesn't go dead too quickly after stringing. Great for intermediate to advanced players who generate their own power and want more control and spin. The playability is crisp and responsive without being too harsh on the arm. If you're tired of strings that lose tension quickly or don't provide enough bite on the ball, Tour Bite delivers that professional-level performance at a reasonable price point. A tournament-tested string that many club players have switched to for its consistent performance.
