Introducing Yamaha Inpres UD+2 Ladies Driver 2021.
The concept of the 2021 model of "inpres UD+2" is "Today's Ichi fires". This is the 3rd generation of the series, which was developed with the aim of achieving both "jumping" and "super straightness" that you can experience just by holding it in your hand. The driver, fairway wood, and utility are equipped with a new technology "SPEEDBOX" that increases the rigidity around the face to prevent energy loss and increase the initial velocity of the ball. In addition, the center of gravity angle and moment of inertia, which are the highest class among clubs of the same weight band, realize directional stability that "grabs" and "does not bend".
Newly equipped with "SPEED BOX" that receives impact energy around the face and realizes an increase in the initial velocity of the ball
A box-shaped dent "SPEED BOX" with a depth of 1.5 mm provided on the crown sole about 10 mm from the face surface increases the rigidity around the face and reduces vibration diffusion to the rear of the head, which causes energy loss, to the utmost limit. However, the impact energy is efficiently transmitted to the ball, and the "flying" is realized by increasing the initial speed.
Both the highest class "center of gravity angle" and "moment of inertia" in the same weight band club
The "SPEED BOX", which increases the initial speed, has a structure that minimizes the addition of weight, making it possible to utilize the excess weight in the head design for the center of gravity design. As a result, Yamaha has achieved both "grasping" due to the center of gravity angle of 34.5 °, and "difficulty in bending" due to the moment of inertia of 5,020 g · cm².
Unique "pleasant sound design" that realizes an exhilarating hitting sound
Yamaha pays attention to the fact that the internal resonance that occurs at the time of impact greatly affects the comfort of the hitting sound, and that the hitting sound has a high correlation with the comfortable hitting feeling, and the comfortable hitting sound is an important performance of the club. It is positioned as one. Therefore, by utilizing the knowledge cultivated as a musical instrument manufacturer and conducting vibration analysis in collaboration with the research and development department involved in musical instrument sound, Yamaha has realized a refreshing tapping sound. This "pleasant sound design" is also used in fairway woods and utilities.
