an XTP question.

Jannick

Rookie
I want to customize my Pure Strike (PO7) to 27.5inch and 350 swingweight.

I'm recieving an XTP buttcap extender tommorow, my question is: How much would that change the HL balance of the racquet, and how much weight would that add?

TW specs:
Strung Weight: 320.35g
Balance: 33.02cm / 4 pts HL


(afterwards I'm going to add weight at 3 and 9 and the handle untill I've reached a static weight of 340gram, swingweight of 350 with a balance of 9pts hl, 32cm)

The two L3 XTP buttcaps I have both way 17.4 grams. I've heard others say it increases the swingweight about 20 points adding them on. That's about all I've got for you.
 
i guess XTP buttcap weight is pretty similar to any otrer buttcap that it replaces, isn t?
I havent weighed it exactly which I now start to regret. But it is an inch longer then the regular buttcap that you have, and weighs about 50% more I'd say.

The balance didnt change alot.

@Jannick - how is your XTP experiment coming along? Are you still using it? Did you end up with the standard 1/2" or did you add a spacer for more extension?

Was very happy with it but because I am chronic frame switcher I changed. The extended ps97 is probably one of the best frames I'd play with though.
 
Can you take a picture of your new set up?

Will try to get a photo in the near future, right now I have my leather grip already installed over it...

It looks just like the regular PS97S, but longer :-)

The buttcap just slides right over the foam handle.

I actually am experimenting with just the 1/2" extension (without the 1/4" spacer). The 1/2" feels better at net (where I try to get as often as possible) compared to the 3/4". It also seems to be a little more stable on the buttcap (the 3/4" was occasionally coming loose, due to less surface area in contact with the foam).

I'm using the L2 for my 4 3/8. I tried the L3 and it makes the butt just a little bigger than I like it. The L2 will fit, it's just really snug and you have to heat it up first to get it to slide on...
 
I'm going to start with a Wilson Blade. I will probably try it on some Yonexes, such as the Duel G, as well. Perhaps the Ultra Tour as well eventually.
 
Hello..most uses of the XTP tennis butt cap do feel a slight build up were the cap goes over the ss ton of handel,grip ,but some users are shaving down this section befor installing the cap,Thus getti fgraz
 
Most users of the XTP tennis butt cap do feel a slight build up were the clap slides over the bottom portion on handle,and some users are slightly shaving that section befor installing the next size smaller,thus getting a 0 build up feel.
But most times not very noticable.
When installing remember the,
"HeatFit" process of heating cap to 155 degrees before installation is key,the cap expands and softens allowing it to conform to different octagonal shapes grips,and you can just pop the cap in your oven at 155 degrees or a heat gun if you have that.Then a small amount of FLEXIBLE rubber cement and can restaple if necessary.

How long in the oven !
 
DeathStrike, To utilize our patented Heatfit process it only requires aprox 5 min in any regular convection oven at 155 degrees to heat a cap up,,quickly take the cap and push firmly down on the pre glued grip of the racquet the heated cap will expand and conform to ANY mfg octagonal shape handel,,its important first to order the correct size cap for your grip. L0/1, L2,L3,L4.
Once the cap cools and contract again and with a small amount of FLEXIBLE rubber cement that was applied normally the cap is very secure, if further securing is needed you can then also Re-staple the cap with any heavy duty staple gun, like factory staples were applied.
Thx..Customizer

Thanks very much available at Racquet Depot in the UK, this is a great easy option so thanks for coming up with something innovative

Fahrenheit or Celsius?
 
CharlottsHead,,155 degrees Fahrenheit,,just pop the XTP butt cap in your oven for 5 minutes at 155 degrees Fahrenheit, this heats the cap up and it expands and softens the cap,,add a small amount of FLEXIBLE rubber cement to racquet handle prior then push the heated cap on all the way it will go on easier since it's now warm and flexible.
Once it's on all the way it cools and contacts and stiffens and locks down on the racquet handel that has a small amount of FLEXIBLE rubber cement, most times this is sufficient for secure installation, and if needed you can also RE-Staple the cap again with any heavy duty staple gun...This is our Patented Heatfit method of getting or cap securely fitted to your racquet or paddle..
We find that many users do not have a Heat Gun so just popping the cap in your regular oven at 155degrees works best.
The key is also getting the correct size cap befor installing..
Currently there are 4 sizes in production these are L0/1, L2,L3,L4.
We find tho that the L0/1 will only fit L0 size grips actually, so if your installing on L1 grips it's actually best to go with the L2 size cap,and for sure if your installing on Yonex racquets as these grips run large.
We also find the L4 cap once heated properly will go on a L5 racquet if you have that gripsize.
Our polyurathane compound plastic we use in production will optimize the HeatFit process best at 155 Fahrenheit.
Hope this helps,and you can contact the XTP people when you order with any questions about installing or correct sizes they will answer questions you have.
Also if at any point you decide you no longer want the cap on the racket or paddle, you can just heat the cap up ,running Hot water on it,then take a exacto knife or razor blade slit down the side of cap and peels the cap off in most cases without damaging the handel of racket.
Thx.Customizer.
 
Just recently learned of this xtp buttcap.

Some questions:

Is there a way to install it without tools (hot glue gun, stapler, etc)

If I have a 3/8 and I don't want it to increase the grip size should I get a 3/8 xtp or 1/4 xtp?

Where can it be purchased in the US?

What length extension is offered? 0.5 inch? 1 inch?

I just got one to test on my prestige. I ordered it from a UK website W&D. At this point I liked the feel so I’m not changing my setup. I ordered the L3 and I had to put down some strips of tape of make up for the extra thickness of the plastic. I’m trying to figure out how to contact the designer to see if there’s a way to make it a bit thinner. My suggestion would be go L2. I’m about to order 4 more L3 butt caps so I have all racquets ready for when I jump back into tournaments.

Thanks, so your racquet is L3, you installed a L3 size XTP?

But you think a L2 size XTP would be better for your L3 racquet?

Yea if you don’t want to basically have to even out the rest if the handle then yes. Fortunately I have a one handed backhand so I did it just enough so that it doesn’t bother me.
 
I have an XTP buttcap and I don't see how you can fit one that is smaller than the size of the pallet, unless you also sand down the pallet so the XTP can slip on.

There is about an inch long section where the XTP buttcap surrounds the existing grip, and this section is about one grip size larger. If you just use the XTP, you fill feel a very noticeable step up in size right in the middle of your palm. The way I found to "fix" that was to add a full thickness heat shrink sleeve to the portion of the grip not covered by the XTP buttcap. This will increase your entire grip by one size, and add probably 35 grams of weight. My L3 size XTP buttcap weighs 22 grams by itself.

The owner/designer lurks around the forum too... I can’t remember the forum name, but if you do a general XRP search, you should be able to figure out.

Your fix is exactly how @Geoff and I discussed doing it. On my Prestige MP L3 the XTP Buttcap slid right in without any force. It did make it a bit bigger which is why I suggested in the previous post to go L2. For me it wasn’t that big of an increase so I’ll just keep the set up and match my other racquets.
 
Hello,,the XTP Xtended Tennis Product is my Patented design and product.
I currently have 4 different sizes in production using our patented Heatfit technology, Heatfit is our specific blend of polyurathane plastic once heated up to 155 degrees can fit ANY MFG.RACQUET that has octagonal, 8 sided racquets or paddles handel.
Most users are Tennis players but we are finding more and more Pickleball players using this also.
Our 4 sizes offered now are L0-4.0 grip,L1/2-4 1/8 & 4 1/4 grip,L3-4 3/8 grip and L4-4 1/2 grip,,we also have found that our largest L4-4 1/2 cap will most time also fit a 4 5/8 grip also once the cap is heated up and expands.
The best way to install the the XTP cap is first remove the factory butt cap from your racquet or paddle, normally there are 4 staples holding this on.
Once you remove the factory butt cap and clean any dirt or residue from handel your ready to install.
Heating the XTP butt cap can be done with a heat gun or even a high watt hairdryer, but we find Simply to put the cap in your oven at 155 degrees for 5 minutes,no hotter than 155,this way the cap is heated a completely and evenly, .You should have some form of FLEXIBLE rubber cement handy,we find that Gorilla glue Clear Grip or Barge shoe glue to work very well as these glues are slightly FLEXIBLE, Do not use super glue. The racquet or paddle needs to slightly flex.
Put a thin coat of glue on handle of racquet approximately 1 inch up,and when taking the Heated cap put a quick thin amount inside cap,,then take the Heated cap and push firmly down onto the racquet handel,the heated expanded cap should slide and comform to the handel and as it cools it contracts and shrinks again to lock down on Any mfg racquet or paddle.
You can also RESTAPLE the cap if needed for hard to fit installations when needed.
Its important to know what size cap your needing so ordering the correct size is very important.
The XTP Xtended Tennis Product will in fact build up the size grip were it fits onto your handel by 1 size.So if your installing onto a L3 racquet the XTP butt cap will feel like a L4 were the cap fits on.
SOME users are in fact slightly shaving down their handel to accommodate the smaller next size smaller cap thus by doing this they get the NO Build Up Feel.But most users are not going to this trouble and the slighly larger feel of normal installation is not a problem,as a matter if fact many users actually enjoy the slighly larger feel many times.
NOTE:Not all racquet handels can be shaved down and are hollow so use caution,Racquets with plastic or foam pallets can be easily shaved down.
Also the edges of the XTP cap can also be rounded off with any file if a more rounded bottom feel is prefered.
Our current in production cap is designed to extend any racquet or paddle 1/2 inch,but some users are getting slightly more by attaching a thin spacer on the handel bottom befor installing the XTP cap and some users are telling us with extreme cases of Stapling and customizing they are getting 1 full inch of extension. BUT the more you extend the cap off the end of racquet the more unstable the cap becomes So Beware.
We are currently testing new technologies and designs to improve the product so stay tuned on that.
Www.xtptennisbuttcap.com is an informational site that can link you to purchase of caps.We offer a single cap or ,2 pac,3 pac,4 pac and 5 pac options with savings as you go,you can also mix and match your sizes as needed,just be sure to note this is special instructions on order form.

Thanks for replying on here. Do you think it would be possible to make the plastic that goes over the handle a tad thinner? The product itself so far after 2 hours of play feels fantastic but we were wondering when installing them if it could be made a touch thinner. On an Instinct Pro L3 it fit much tighter than my Prestige MP L3.
 
Tried one of these on a wilson clash and it felt great, the stringer had no cement type glue so he used double sided tape and heavy duty staples, he said even the tape wasn't necessary but more of a precaution.... great company ! cheap option for extending frames
 
Longtimelurker..thank you for the feedback,and yes the FLEXIBLE rubber cement isn't always needed but many times is,it all depends on the fit,heating the cap up helps expand an softens the cap an many times if a good snug fit is accomplished the cement may not be needed,but so many different mfg,Wilson,Head,Babolat, Yonnex ,Prince are all slighly different with sizing or shape,yet this XTP cap can work if needed for most simple stretch customize jobs like this.
I'm just about done with the newest cap we are putting into production, it going to be a true L1-4 1/8 size cap..Currently we had a cap we called L0/1 but this cap in fact would only fit true L0- 4.0 grips so anyone that had a L1-4 1/8 grip had to use our L2 cap and in most cases it worked well enough,but we are seeing now more and more pickleball players using the XTP caps on paddles so we decided it was time to get a L1 cap into production to cover them also.
Yesterday I received feedback from a user that installed a L2 cap on there Babolat L1 4 1/8 tennis racquet and they said that the L2 cap actually fit their L1 grip very well,so go figure its always a bit of fluctuation on these products.
But we should have the newest L1 caps on our website www.paddles4less.com in about a month and available.
Many users are slightly shaving down the handel so once the cap is installed the-No Build Up-feel is achieved but alot of players actually like the slight build up and not bothered by that.
All in all like you say its a very simple fix fir anyone wanting to slightly stretch a racquet or paddle half an inch or slightly more in some instances.
Thanks the customizer.

Raizu..thanks for feedback, all mfg are slighly different so we understand the delima here,but in most cases the cap will fit and function,gluing or stapling can drastically help securing the cap ,but as far as thinner so less build up is felt is what we have right now,some players actually like the slight build up feel,or they are shaving the handel down slightly befor installing in some cases and then installing the next smaller cap for no build up feel.

Awesome! glad these are available worldwide too. Looking forward to some more advancements in the future. Would also love to see a 0.25 extension also. Keep up the good work.
 
@Customizer

mentions customers shaving down the handle and installing the next smaller cap for no build up feel. I would like to do this but I am anxious about permanently messing up the pallet by screwing up the shaving part. Does anybody have a good reliable method to achieve this- get the absolute right amount of shaving down consistently on each face- to know it's right *before* heating up the the cap in the oven and finding it then doesn't fit, or find you've done too much and it'll never stay on or will have a build *down* on the butt cap, or find that you have done it unevenly...? :)

Penguin..lots of variables on how much to shave down so the next smaller cap can be installed for the no build up feel.but generally its about .4 of a millimeter the cap wall is 1 millimeters thick so shave it down on all 8 sides of your handel .4 millimeter. Then the next smaller size cap can go on usally and give an very same size Xtension with the XTP butt cap. Now not all racquets or paddles have pallets some are just hollow and not a good idea to shave down a hollow handels much.but many customizer users are modifying and getting an easy way of Xtending racquets half an inch with XTP. Thx.customizer.
 
If you are worried about the weight/swingweight, you can just remove the weights from the racquet and rebalance it afterwards. Nearly all but a few 'lite' model racquets have weights in then:.
Here's a f 2.0/6.1 95 I recently did:

 
If it is held by friction, warm the plastic with a hot air gun, hair dryer or hot water. If using hot water, the water only needs to be warm enough to make the plastic pliable. 8-B
 
Used a heat gun to add l3 cap to l3 Prince response. One side would not shrink down as much as the others. Decently on. Used rubber cement. Felt secure. Pretty bulky at end. Tough to serve. Played outside in heat and it came right off. Total time on about Two hours.

You still need to staple it in. I’ve been using them for 3 years and the staples are 100% necessary with all caps.
 
Yeah thanks for the confirmation. Idk why that wouldn’t be made clear. God bless the people using it with nothing but friction keeping it locked in
Lmao agreed. I’ve had to restaple only 1 and I’ve switched them racquets a few times without a problem. Great product.
 
I don’t have the convention staples that companies use. I borrowed a staple gun used for sowing so I use 2 shallow staples on the 4 sides. 1 mid way up and one at the bottom before the “buttcap”
 
When I had my XTP butt cap on, I'd just a pathfinder awl to poke a hole in the XTP to match up with the hole from the original staple. I'd then just re-use the original staple. It was a snug but not super tight fit, but more than good enough to prevent the XTP from sliding on the handle.
