The Penley Performance Ring System is the latest innovation from Penley Sports. This uniform identification method will, for the first time, inform the player about the combined material and design functions for each golf shaft. Golfers of all skill levels can now evaluate the performance characteristics designed into each shaft and properly choose the correct equipment for their games.
Ring #1 Design Criteria
The ring closest to the grip identifies a shafts design and material performance characteristics. Penley uses only the highest grade (made in USA) materials throughout the production process. Each shaft possesses various material components (i.e. composite) such as premium grade high modulus, high strength fiber patterns, boron, and Penley's proprietary materials. Penley's engineering group then designs patterns that optimize shaft performance for each skill level.
5 Designed to maximize the transfer of increased loads that are associated with stronger players.
4 Designed to accommodate players who desire lighter weights to increase swing speeds.
3 Designed to increase performance characteristics of players with average swing speeds.
2 Designed to improve overall playability features for slower swing speeds.
For Optimum performance, Penley recommens the following swing weight range fo me (D-2 to D-8)
Ring # 2 Flex
The second ring from the grip identifies flex. Flex is measured by a shaft's resistance to bending. Penley measures flex by determinging a shaft's CPM (cycles per minute) from a fixed point. Typically, a slow precise swing will benefit from a greater amount of flex while a very strong (professional) swing will benefit from very little flex.
5 Extra Stiff-Developed for players with swing speeds of 110+ mph (265+ CPM)
4 Stiff-Developed for players with swing speeds of 95-109 mph (255-264 CPM)
3 Regular-Developed for players with swing speeds of 85-94 mph (245-254 CPM
2 Seniors-Developed for players with swing speeds of 75-84 mph (235-244 CPM)
1 Ladies-Developed for swing speeds up to 75 mph (up to 234 CPM)
Ring #3 Torque
The third ring from the grip indicates the amount of torque. Torque is measured by a shaft's resistance to twist. Torque is calculated in degrees typically running from 2.0 (low) to 5.5 (high). Players with slower swings usually need more torque as the twisting of the shaft will assist in squaring the club face.
5 Lowest Handicap (PRO) 1.0 to 2.5
4 Mid Handicap 2.6 to 3.9
3 Seinor Player 4.0 to 5.4
2 Ladies 5.5 to 7.0
Ring #4 Flex Point
The fourth ring from the grip indicates the flex point. The Penley Ring System identifies the physical location of the flex point for each shaft allowing a player to select matched flex points to ensure uniform fell and consistent performance.
5 High Flex Point-The choice for players who prefer lower trajectory and increased roll.
4 Mid Flex Point-Standard flex point position for players requiring a mid range launch angle.
3 Low Flex Point-This flex point allows the greatest kick point producing higher launch angles and increased carry distance.
Based on a 45" finished club (driver) length. Calibrated readings from Penley Factory equipment. 10.5 degree driver.
