A customer directed golf club head manufacturing system including a self-service kiosk configured to transform a club head blank into a finished club head based upon input of a user. The self-service kiosk including a plurality of club head blanks, a kiosk control system, a user input system, and a machining system. The kiosk control system configured to prompt the user to select a plurality of predefined options that influence the configuration of the finished club head. The kiosk control system receives the user selected predefined options, identifies at least one user specific club head blank from the plurality of club head blanks that meets the requirements of the user selected predefined options, creates machining instructions, and transmits the machining instructions to the machining system to machine at least a portion of the user specific club head blank in accordance with the machining instructions to create the finished club head.

A gauge for cartridges is disclosed. The gauge includes a gauge body defining an opening, a window, and receiving space. The opening and the receiving space share an axis and are in direct communication with each other. The window is in direct communication with the receiving space. The opening and the window are separated by a body portion of the gauge. Each gauge has a receiving space that is sized and shaped to correspond to a predetermined cartridge.

A system for quickly determining if a hockey skate blade is bent is disclosed. The system is a quick and effective way to determine if a Hockey Skate Blade is bent which will affect the ability for the blade to be sharpened and skating performance. The disclosed system is a simple way to quickly ensure skating performance and blade sharpness are optimized.

An object of the present invention is to provide a golf ball traveling a great flight distance. The present invention provides a golf ball comprising a spherical core and a cover covering the spherical core, wherein the golf ball has a ratio (t2/t1) of a time (t2) to a time (t1) of 1.05 or more in a hitting test using a driver (at a head speed of 40 m/sec), wherein the time (t1) is a time taken from a moment that the driver begins to contact with the golf ball to a moment that the golf ball reaches a maximum deformation amount, and the time (t2) is a time taken from the moment that the golf ball reaches the maximum deformation amount to a moment that the golf ball leaves the driver.

An ice skate blade edge measurement device includes a measurement device frame and a measurement indicator. The measurement device frame defines at least one storage location for the measurement indicator such that, when not being used to measure an alignment of a pair of sharpened skate blade edges, the measurement indicator can be stored. One storage location can be on a front side of the measurement device frame away from a measurement location and another storage location can be on a back side of the measurement device frame.

A shaft 6 includes a tip end Tp and a butt end Bt. If a shaft length is defined as Ls, a distance between the butt end Bt of the shaft and a center of gravity G of the shaft is defined as Lg, and a ratio of the distance Lg to the shaft length Ls is defined as a ratio of the center of gravity of the shaft, then the ratio of the center of gravity of the shaft is equal to or less than 47%. The shaft length Ls is equal to or less than 991 mm. If a forward flex is defined as F1 (mm) and a backward flex is defined as F2 (mm), a flex point ratio C1 of the shaft calculated by the following formula (1) is equal to or less than 39%:

C1=[F2/(F1+F2)]100](1).

Bicycle saddles come in many different shapes and sizes. Some are long, some are short, some are curved some are flat. The ultimate goal is to find the perfect saddle for the cyclist.

CLARIFICATION: those that ride bicycles are commonly referred to as cyclists, bikers, cyclists, bicycle cyclists, bicyclists, cycle cyclists, cycling, etc., but for this discussion, they will be referred to as cyclist(s)

As with the height of humans, the widths of Ischial Tuberosities (Sit Bones) are also numerous. The Ischial Tuberosities are the protruding bones of the hip/pelvis that sit underneath the muscles of the glute and is the part of the body that first contacts the saddle. Everyone has a different width and the importance for a cyclist in finding the exact width is critical for long-term health and cycling enjoyment.

Excessive weight/pressure on the soft tissue can lead to health issues such as tumors, genital numbness and even erectile dysfunction due to Pudendal nerve compression and or crushing and or blocking of the Pudendal artery.

SADDLE DESIGNThe rear area of a saddle is where the Ischial Tuberosities should rest. This area of the saddle comes in one of two shapes, either (a) flat, or (b) curved. This is where the cyclist should apply most of their weight. The most important item is for the cyclist to minimize the amount of pressure to their soft tissue, in other words, the correct saddle width and saddle shape is paramount in preventing as much of the cyclists' soft tissue from coming into contact with the saddle. Ideally, the majority of contact with the saddle will come from contact of the cyclists' Ischial Tuberosity, the Ischial Ramus and Inferior Ramus of Pubis.

This Ischial Tuberosity measuring tool can measure any/all types of cyclists and can be used to measure any/all saddles where a saddle(s) that the bicycle shop carries can be recommended to the cyclist. It is important to note that the recommended saddle(s) will be the correct fitting saddle(s) for the cyclist.

This saddle fit system is comprised of impression foam pad(s) that are attached to an organic or inorganic substrate that supports the cyclists weight. Also included are 2 ferrous, non-ferrous or non-metallic balls as well as a detached Vernier caliper measuring device.

The cyclist sits and centers themselves on the saddle fit system. The bike fitter then has the cyclist stand thereby leaving 2 indentation impressions on the impression foam. The bike fitter then takes the 2 balls and drops one onto each side of the impression foam pad. Due to the natural force of gravity, these balls will self-center into the exact center-point of each Ischial Tuberosi

A gauge for cartridges is disclosed. The gauge includes a gauge body defining an opening, a window, and receiving space. The opening and the receiving space share an axis and are in direct communication with each other. The window is in direct communication with the receiving space. The opening and the window are separated by a body portion of the gauge. Each gauge has a receiving space that is sized and shaped to correspond to a predetermined cartridge.
