TF-X1 285 Tennis Racket - Rising intermediate players who want to put on more of a show will value the power of this racquet. This racquet is slightly lighter and faster than the TF-X1 300, which will help players who are getting better achieve the stroke speed needed for effective pace and spin. One such technology is the IsoFlex System from Tecnifibre, which uses the bumper grooves of the racquet to create a more even playing string bed. The TF-X1 includes an upgraded version of Rene Lacoste's dampening system for added comfort. Called X-Damp, it filters out harsh vibrations by combining an elastomer support with a steel mass. The TF-X1 285 feels strong, responsive, and comfortable when making groundstrokes. It is very easy to spin, and its light weight makes it ideal for making fast-moving shots. The speed increases at the net, where this stick travels at breakneck speed to make targeting simple. In the end, this is just an excellent choice for the advanced intermediate player looking to increase spin and speed. We don't sell this racket strung. There is no cover included with this racket.
