In the following diagram we shall see how this works. One of the many factors that influence swingweight is the weight of the shaft along with head weight, grip weight and club length. Now customers have a slew of custom shaft options to choose from so picking and choosing another shaft other than the stock option could alter the swingweight and eventual stiffness of the club as most manufacturers only produce their heads in only one weight option. Long are the days were a shaft is available with just the stock option. This specification will be built around one shaft to create a certain swingweight with a particular weight head. Most manufacturers will establish a standard set of specifications for a driver. Need help calculating the swingweight based on the length, height weight, grip weight and shaft's weight and balance point? Try using Hireko's Golf Club Building Swingweight Calculator. So not only does the shaft you purchase becomes shorter, but it also becomes lighter. This means you are lopping off on average over 2.5" of material from the golf shaft. #Fitted stock vs perfect balance driverIn the modern 460cc driver, the shaft now rests close to 1 9/16" above that ground line meaning that the cut length of a shaft for a 45" driver is 43.19".įor clubmakers out there, you are used to purchasing graphite shafts that are for the most part 46" long. Secondly, few heads exist today where the shaft goes through the bottom of the sole but stops at an arbitrary position above the ground line. The club length is measured from the ground line up to the edge of the grip cap along the back side of the shaft, which factors in the extra material at the end of the grip (approximately a quarter inch). Instead of calling these standards, it is better to establish these as benchmarks.Īnother important consideration is the shaft installed into a 45" driver isn’t the same length but shorter for two reasons. Lastly, the average driver head will weight approximately 200g. In the next year the typical driver will start to vary greatly, but for now let’s say the average driver length is 45" long and equipped with a 65g shaft and 50g grip. No, we are not going to uncover a conspiracy, rather break down the components of how head weight, shaft weight and balance point directly affect what length and swingweight your next driver (or customer’s) should possibly be made to. #Fitted stock vs perfect balance driversHead Weights, Shaft Weights and Balance Points – Oh My! Why Drivers Vary in Length and Swingweightĭo you ever wonder why drivers are a particular length or swingweight? And why they aren’t necessarily uniform throughout the industry? The answers to these questions might be more complicated than what they appear.
