Customization. What it can do for you!
Where is my power?
Tennis players want power, control, spin, comfort, durability, and fun!
Well, so do we!
We collect data to contribute to your greater enjoyment of tennis, so we are including this video to address some questions about power!
Because we do not know how you are swinging the racquet, fast, slow, or in between, we must rely on data (numbers) to help us help you.
Pro Stock & Special Make Up (SMU) Racquets
Pro Stock & SMU racquets are a huge part of our business and Pro Stock and SMU’s continue to grow!
Soon, we are going to post the current inventory of Pro Stock and SMU racquets that are at the World Headquarters; however, in the meantime, please visit our YouTube channel to see and hear more about what we do.
We receive the racquets in the uncut, raw state, then make them yours.
The finished Pro Stock(s) are made to your specifications:
- Length: Up to 28 inches
- Weight
- Inertia (swing weight)
- Grip pallet: Head TK82 (flat) or TK82S (round)
- Perfect Pallet: Custom Printed Soft Grip System
- Grip size: Size 2 to 4
- Grip Material: Leather or Synthetic
- String
A Wilson RF 01 300 Extended
We want to share the specifications of an extended (70.0mm/27.559) Wilson RF 01 300.
The lengthening process involves removing the staples holding the butt on, which needs to be done carefully for the integrity of the foam pallet, before proceeding with the next steps.
Any time the butt cap comes off a racquet, the first step is to fill the open shaft with a stopper, preferably cotton, to the desired depth for fitting or protection. If the racquet is “foamed” some of it is removed.
Numerous small details go into the extension we design and print, so we will not go into all of those right now.
The area that will accept the extension is filled with a new two (2) part epoxy made by Starbond. This epoxy is nearly fully cured after several minutes; however, we prefer to let it cure overnight before proceeding with any other work.
After the curing cycle, the butt cap is installed. We do not use staples in most cases, only a chemical adhesive. Staples can easily damage the original foam pallet and the extension if the location is not ideal.
If you make it to the end of this data table, you will find some comparison data. This data is a glance at what has changed from the original 27-inch length. This is a specific racquet, so your specifications, if extended, may differ.
This is enough small talk, so let’s take a look at the results of the extension.
