Regardless, good luck with it because it's a good frame, particularly with some lead added.
Are you sure it's not the IG Pro model which has 335 grames ?
Usually fakes have less than 300 grames . A real IG Speed has a code printed on the exterior of the grommet at 5 o'clock on one side of the racket.
