Head Graphene 360+ Gravity Tour
Head is adding another racquet to the very popular Gravity Series! This racquet is the Gravity Tour and in a nutshell, is a lighter version of the Gravity Pro. Both are 18 x 20 string patterns and, the Gravity Tour is a 22mm beam as opposed to a 20mm beam for the Gravity Pro.
You would think the 22mm beam would be stiffer (power?) than the Gravity Pro, but in this case the extra weight of the Gravity Pro makes it a little more power forward. Our tests show the RDC stiffnesses to be the same (60), and the FlexFour shows the Gravity Tour slightly stiffer in the shaft, 51 as opposed to 46 for the Gravity Pro.
From a numbers standpoint this racquet (14 grams lighter) will fit a player wanting a little more maneuverable racquet but not as powerful as the Gravity Pro. ← Click on this link to see the review.
This review is of a “play ready” racquet. That is an over grip, and vibration damper. These accoutrements do contribute to weight and swing weight to a minor degree.
