This lighter update to the Revelation Pro features a lighter head balance, making it maneuverable and quick around the court. It's ideal for you if you're an intermediate or advanced player. Play with maximum comfort. Sonic Core made with Infinergy® is located in the 2 and 10 o’clock areas of the racket, dampening impact shock and reducing frame vibrations by up to 37%, resulting a more comfortable hitting sensation and a reduced chance of injury.
