The Cleveland CBX2 Wedge For the Cavity Back Golfer

The Cleveland CBX2 wedge is out and although it may look like the average blade “at address” it is totally new and AWESOME! (Check out Cleveland’s video below to see just how awesome it is!)

Your short game is one of the most critical elements of having any success in golf, yet so many players don’t give it the attention it deserves, both in equipment and practice.

Well, the new Cleveland CBX2 wedges were created to solve half of that equation.

Cleveland decided that rather than creating the usual blade style wedge, that they should instead create a cavity-backed wedge for “the cavity-backed golfer.” Their goal is to help the everyday golfer lower their scores and gain consistency in their short game.

To give the everyday golfer this kind of consistency, forgiveness, and control with a wedge, they have done a few things that have created a huge impact.

1.) Impossible Center of Balance

These are their words, not mine, but ultimately Cleveland has a centrally located center of gravity rather than the usual heel based COG so that the clubface can work with you to be square on impact with the ball.

They have been able to do this by reducing weight in the hosel, creating cavities in the back of the club, increase the width of the sole near the toe without changing it much near the heel and more.

All of this has come together to create a center of gravity that is right in the middle, near the bottom of the face, perfectly positioned to help you hit more consistently!

2.) Dynamic Sole technology

With this new wedge, they have created a dynamic sole that varies in width between the heel and sole of the club to allow for even more forgiveness both on chunked shots, topped shots or those that you hit on the heel or toe.

Additionally, this helps to maximize the perimeter weighting of the club giving you even more guidance to keep the clubface square and on target.

3.) Hollow Cavity Design

Next and most notably is the hollow cavity design of this wedge.

Usually, wedges tend to have a blade style for both the aesthetic and to appeal to the liking of golfers, however, this wedge has been specifically designed to have a cavity back all while looking like a blade.

Why?

Because doing this allows this club to give you more forgiveness and prevent you from chunking the ball so that you can hit more consistent shots and get even more overall forgiveness.

4.) Rotex Face Technology

Lastly, this Cleveland wedge comes equipped with Rotex technology on the face which combines grooves with more grooves and then even more grooves so… you’ll get the spin you want on the ball.

This technology creates awesome spin for almost any golfer who is looking for those one bounce stops on the green!

Overall, these new wedges are packed with features to help the cavity back golfer finally get a wedge that fits their playing style.

The Ultimate Guide to Buying Junior Golf Clubs

Picking the right junior golf clubs doesn’t have to be difficult. There are many options out on the market today for kids and it may seem a bit overwhelming, but we have compiled a handy guide to help answer the most common questions we receive and steer you in the right direction to picking the perfect set (or a couple of individual clubs) for your junior player!

FAQ Page

What are junior clubs?
Junior clubs are specially designed equipment that is more flexible, lighter in weight and more lofted to help young golfers find success out on the golf course.

What ages are junior golf clubs for?
Golf clubs are available from size zero (age 3) all the way through a golfer’s teenage years (age 17).

What are the best junior golf clubs?
We stock several manufacturers of junior golf equipment. Our best-seller of junior golf clubs is from U.S. Kids. They have clubs available for toddlers all the way through a golfer’s formative high school years and everything in between. Our second best selling brand is PING.

What sizes are junior golf clubs?
U.S. Kids Clubs offer 11 different sizes available based on the strength, age, and height of the child.

What height are junior golf clubs for?
Junior clubs are sold from size zero sets for kids 36” tall all the way up to kids 69” tall.

Can adults use junior golf clubs?
Definitely! Many petite women find that kids built traditionally for youth are a great option to help them play their best game.

How do you measure a child for golf clubs?
Start with the child’s height. For U.S. Kids clubs, measure the junior with their shoes ON. Every three inches marks a new size. The height is important because you don’t want the club to be too long. After determining the height, you should also measure the player’s swing speed (for their driver) to determine if the child should choose a U.S. Kids Ultralight or Tour Series club. Children ages 7 and under will always choose the Ultralight but the Tour Series is available for older children.

U.S. Kids Fitting Chart for Junior Golf Clubs
U.S. Kids Fitting Chart for Junior Golf Clubs

What clubs are in a junior golf set?
It varies based on how old the child is and how avid of a player they are, but most sets come with a minimum of 5 clubs and as many as 11.

How many clubs do I need to buy?
You can buy as few as a single club or as many as a full set. A putter and a 7 iron is a great way to get a child started to see if they like the game. With those two clubs, they can hit balls, chip, and putt. These two clubs are also the easiest to hit and will bring early success to a beginning player.

Should you cut down adult clubs for junior golfers?
No. When you cut an adult club down, you make the shaft much too stiff and much too heavy for a child to swing easily. Junior clubs are engineered for getting the ball airborne easily and built lightweight. This will maximize a junior’s ability to successfully reach their potential.

The Science Behind Golf Rangefinders

One of the most popular tools of golf, rangefinders have changed the way hundreds of thousands of golfers approach the game. These modern gadgets allow golfers to know precise distances to flags, greens, hazards, and more. How do these work though? We go into the specifics of how golf rangefinders work.

If you look at the end of a laser rangefinder you’ll see two black circles. One of these circles is a laser emitter. When you point the rangefinder at an object and press the button, a laser beam will be emitted from this black circle and hit the object.

Once the laser hits the object you’re trying to measure, a portion of that laser will be reflected back towards the rangefinder. That reflection will hit the second black circle. This circle is a receiver aperture.

The third and final major piece of a laser rangefinder is a highly accurate clock. This clock records when the laser beam is emitted and then when the receiver aperture detects the laser reflection.


GolfBuddy Laser 1S Rangefinder

The rangefinder will then process the information. Utilizing the time it took the laser beam to leave the emitter and reach the receiver, the rangefinder can estimate the distance that it traveled. Hence the rangefinder can measure the distance of any object it can bounce the laser off of.

Sandpaper Attached to Wedge?

It’s common knowledge that wedges should produce spin. It is difficult to find explanations for how the grooves on a wedge produce spin. Most people say grooves increase friction. Does that mean a wedge with extreme friction would be excellent? To find the answer, we built a sandpaper wedge and tested it against a normal wedge.

Research:

Researching why wedges have grooves yields a wide assortment of differing answers. Therefore, for this section, we will stick to the cold hard facts. Nearly everyone agrees that grooves were originally introduced to deal with the grass and debris that comes between the clubface and the ball. For example, a club without grooves would perform like racing slick tires. These tires perform exceptionally well on clean dry tracks. However, in wet or dirty conditions particulates prohibit the tires from making adequate traction with the road. This is the same problem faced by golfers. Therefore, club manufacturers have carved grooves into the surface of wedges to give the debris a channel to escape. This is comparable to the patterns on normal road tires. Now, if the grooves just provide more traction then why does the USGA care about the type of edges the grooves have? This is because the grooves provide spin characteristics. Specifically, how they accomplish this is not adequately explained by manufacturers. Nonetheless, there are some solid theories. 

Hypothesis:

My theory is the spin a wedge imparts on a ball has everything to do with the friction the club creates against the ball. Hence, grooves create friction when the surface of the ball encounters the sharp edges of a groove. This contact creates friction and the ball generates spin. The grooves also channel water and residue away from the surface of the ball. However, this experiment is in dry weather so this attribute will not matter. I theorize that the more friction the face of the wedge has, the more spin it will inevitably transfer to the ball. By adhering a textured surface of sandpaper to the face of a wedge the ball will have a much lower launch angle, more backspin, and a shorter rolling distance

Procedure:

We acquired two slightly used Alister Mackenzie Limited Satin Wedge. Both wedges are 52-degree wedges with the same bounce angle. We attached a piece of 140-grit sandpaper to the face of one of the wedges. This sandpaper was attached with two-part epoxy resin. We chose this resin because normal glues would not withstand the high impact of a golf wedge. We then went to the Player Performance Studio at Haggin Oaks to use the TrackMan system. Utilizing this system, Calvin Carpenter, a teaching professional, hit 3 sets of 3 balls with each wedge. We analyzed the results of the TrackMan and made a determination on the purpose of wedge grooves. 

Results:

The results of this experiment are incredibly interesting. The sandpaper wedge had 62% more spin than the stock wedge. The sandpaper wedge averaged a spin rate over 10,000 rpm. Likewise, the launch angle for the sandpaper wedge was 21% lower than that of the unmodified wedgeThe landing angle for the sandpaper wedge was also less than that of the stock wedge. As for consistency, the sandpaper wedge again came out on top.

Conclusion:

Our conclusion is that friction has a direct relationship to spin. Increasing friction increases spin. Our high-friction and grooveless wedge performed better than its stock counterpart. This strongly supports every point in our hypothesis. While the sandpaper wedge may be inferior in very wet or high debris situations, in dry conditions it is unarguably superior. However, on our ninth swing with the wedge, the sandpaper tore. Additionally, because we used a strong two-part epoxy it would be difficult to replace the sandpaper with a new piece. It would require a more durable design for this to useable on the course. Nonetheless, this experiment hopefully shed some light on how a wedge works.

Fastest Golf Cart In The World

If you’ve ever felt that the speed of golf carts at your local course was lacking then you’re not alone. Golf cart manufacturers typically install controllers into their vehicles which limit the top speed anywhere from 14 to 19.9 miles per hour depending on the state. However, there exist golf carts that can travel over 100 miles per hour!

Rules and Regulations

The rules and regulations pertaining to golf carts vary state by state. Hence, we will discuss the rules for California as that is where we are located. Here, golf carts may not exceed 15 mph, carry more than two people, nor way more than 1,300 pounds.

These rules sound very limiting but luckily the law has a caveat. The law says” If you modify your golf cart to go faster than 15 mph or seat more than two persons, the vehicle is considered a regular motor vehicle and must comply with federal motor vehicle safety standards (FMVSS) for regular passenger vehicles. These standards include additional vehicle equipment, appropriate FMVSS labels, applicable emission standards, and a 17-digit conforming VIN. Failure to comply with all necessary regulations may result in a citation. Equipment requirements for on road use. Your golf cart must comply with certain equipment standards established by the California Highway Patrol (CHP) to be registered for on road use.

This law and other likes it in other states allow for “speed fiends” to build some truly ridiculous vehicles

World Record Holder

One group of “speed fiends” currently leading the industry in fast golf cart builds is Plum Quick Golf Cart Racing. The company currently holds two Guinness World Records and numerous other awards. One of these records is the world record for fastest golf cart. Traveling at 118.76 mph this cart can outrun most cars.

How Did They Do It?

There are a few ways to get golf carts to go faster. First, you can over-volt an electric motor. While this harms the motor itself it can make it produce much more power. Obviously, Plum Quick Motors can’t make the stock golf cart motor move the cart at almost 119 mph even by overvolting it. Therefore, Plum Quick replaces the stock motor with a larger aftermarket one. Thirdly, make sure to bypass any speed regulator in the stock controller. Fourth, regear the axles and/or add larger tires. Both of these will allow the electric motor to better use its torque. Next, be sure to upgrade the brakes. If you’re gonna make your cart go faster be sure you can make it stop. Finally, be sure to add any necessary safety equipment required by law. California and most other states require safety modifications in conjunction with any significant performance upgrades.
