Andrey Rublev has officially switched to Head Gravity Pro racquets. Rublev has been playing with a blackout racquet for some time. He was also apparently under a racquet contract with Wilson, which just expired.
Andrey Rublev was playing with a Wilson Six One 95 until a year ago before switching to a blacked-out Head Gravity Pro. Alexander Zverev also endorses the Head Gravity Pro.
Head Gravity Pro is arm-friendly with a flex rating of 62. The large 100 sq. in. head gives a big sweet spot for players to hit through. With an 18×20 string pattern, the racquet has excellent control and touch.
