PRGR introduced the SPEED TITAN TR driver, developed by focusing for the first time on the "flexion" of the club face. Its three-point convergent head, on which the face center, the center of gravity and the maximum flexion point were integrated into a single point, produced an amazing coefficient of restitution (COR)as high as 0.852. The long flight distances achieved by this driver amazed pro golfers.


PRGR introduced the DUO, a driver with a new structure consisting of a carbon crown and a titanium body, transcending high repulsion performance. This DUO structure provided three benefits at the same time: high initial speed, high trajectory and low spinning. Intensifying high-repulsion competition among golf club manufacturers was almost reaching an impasse, since it caused restrictions on high-COR golf club use due to revised tour rules, club face durability problems, and other issues. At that time, the Duo created an enormous sensation, pushing open a new frontier, and subsequently kindling the "composite head" boom.


PRGR introduced the egg IRON, heralding the subsequently launched egg series. The egg series was later recognized as a novel club series. It was created under the concept, as the name implies, of "not being hindered by conventional ideas," of "creating an idea as innovative as the way it is born as if by breaking an egg shell" and of "giving top priority to the development of performance (long flight distance and ease of hitting)."

Also in 2007, PRGR introduced the SWEEP series for women with a head speed of 30 meters/sec or lower. In addition to its fashionable design, the series offered a wealth of performance features friendly to female golfers, such as a head with a built-in flight distance display unit and a coaching grip, which are gaining popularity. The series has been renewed and continues to be available today.


The egg IRON received the 2008 Japan Good Design Award.
PRGR also introduced the egg SPOON, a spoon with a new club shape designed based on determined research on maximizing flight distance. It was the result of the exhaustive pursuit of lowering and deepening the center of gravity.
Though originally developed for amateur golfers who were not able to swing 3W clubs, its long distance performance made this model popular even with pro tour golfers.

Yokohama Rubber Co., Ltd. launched the Yokohama Tire Golf Tournament PRGR Ladies Cup, one of the tournaments for the Ladies Professional Golfers' Association (LPGA) of Japan.

PRGR introduced the TR Driver Model 500. Pro golfers using this driver have won tournaments, totaling seven wins during the year, when both men's and women's tours are combined. They included a win (by Ji-Yai Shin) in the major championship, the Ricoh Women's British Open, allowing the club to be showcased in the British Golf Museum in St. Andrews, to join the other winners' clubs.

In the same year, the directly run PRGR Ginza store launched Science Fit, a swing diagnosis service using a new concept. Its high precision compels even leading pro golfers in Japan to use this service to check their swings and to maintain their clubs.


PRGR introduced the iD series under the key concept of fusion between inspiration and data. PRGR proposed an unconventional three-balance design for the optimal location of the center of gravity, highest initial speed point, and maximum flexion point.


PRGR developed "iD nabla," which drives a ball with an inverted triangle. To achieve a sense of swing that is continuous from the driver to the irons, "iD nabla" used the "nabla center-of-gravity design," which brought continuity to the design of the center of gravity. Rather than using conventional designs, which prioritize the shape, it was designed to obtain a consistent sense of swing across the entire club set by achieving continuity, from the driver to the irons, in three center-of-gravity design values--FP (face progression), GR (value obtained by subtracting the FP value from the center-of-gravity depth), and FGL (the distance to the center of gravity on the surface of the face)--that significantly impact the performance of the club.


PRGR launched the club series "SWEEP" for female golfers. "SWEEP" is designed for female golfers with a head speed of around 30 m/sec and achieved improved performance which can easily catch a ball and lift it easily with the same swing across the entire club set by designing the entire club head, except the putter, with a shorter center-of-gravity distance and a deeper center-of-gravity depth. It has a high-class-feel finish that is suitable for adult women, with chic Bordeaux as the dominant color, which is accented with pink.

PRGR developed a new driver of the "egg" brand, "NEW eggbird DRIVER." The characteristic feature of the "egg" brand is the pursuit of flight distance. This new driver is lightweight, has a long shaft (47 inches, longest among PRGR products), and is elongated up to the GiriGiri upper limit of the R&A measurement rules so as to extend the driving distance further. The new product used a lightweight head and a "flexible" shaft that was developed jointly with Fujikura Rubber Ltd.


PRGR developed a new driver, "iD nabla RS." The "iD nabla RS" series is being developed for athlete golfers and golfers who are trying to improve. It is particular about the "level of perfection" and considers parameters such as the shape of the head, flight distance, directionality, and sound and hitting feel. Not only the specifications but also the inspiration of golfers were embodied in the club through PRGR's new technologies.


PRGR developed the "SUPER egg" series, which does not conform to the SLE rules, and the "egg" series, which prioritizes distance while conforming to the rules, from the "egg" brand for senior golfers. The "SUPER egg" series is intended for senior golfers who are less enjoyable with golf due to a drop in flight distance with age. The model consists of driver and irons with enhanced resilience and can only be used for private play. The "egg" series is intended for senior golfers who want to achieve a further flight distance, hit with greater ease, and enjoy competitive play as well. It consists of the driver, FW, UT, and irons.
