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.

The GSW Women’s Tennis Team
The women of GSW tennis jumped off to a great start by winning the home opener!
Congratulations to Madeline, her teammates, and Coach Coach Karlie Levering for leading the team!
GSW Women’s Tennis
We have been working with Madeline’s racquets (Wilson Blade with Ashaway MonoGut ZX string) for several years and are happy to continue supporting Madeline and her team!
Wilson H-22
We have a few Wilson H-22 at the World Headquarters!
These are custom racquets, so any resemblance to retail racquets is cosmetic! These racquets are cut to a length of 27 inches (68.6mm) and have no grip, and the butt cap is not stapled to the pallet! This means it is ready for a Wilson Leather grip (or standard synthetic) and some minor length adjustment if necessary.
Wilson H-22
There is a well-deserved mysticism around this iconic racquet model! This racquet has been in the hands of many top professionals over the years and probably many right now! The relatively thin beam and box cross-section create a predictable and consistent racquet.
These racquets are customizable to achieve the perfect hitting experience for the player seeking a “companion” not just a racquet!
Wilson Shift 99L Yes it is HERE!
This could be the Shift you are waiting for!
The Wilson Shift 99 L
The same new technology in a slightly lighter package!
We will post all the specifications soon but we wanted to let you know they are here!
I believe this will be a great platform for future growth! The swing weight is a little low. However, that can be changed as necessary to achieve the growth in performance. The stiffness of this racquet does lend to the power shown in the specifications, but the lateral bending will benefit those looking for comfort.
