Xpider Down Pressed Clamp Base

Vladimir18061953 · Jul 8, 2019

Good day stringers,
Recently I received new down pressed clamp bases from Xpider Co.,Ltd. Whole set consists
of 2 clamps, 2 bases with rails. My stringing
machine is Tourna 300-CS. I changed crank
mechanism on Wise 2086 electronic tension
head and installed new clamps set. This up-
grading works very well. New clamp bases really increase speed and comfort of stringing
process. Bases moving is easy and smooth.
Fixation of bases by palm is comfort. There are 3 ways for release of bases: clamp drop,
releasing button pressing, lever lift by fingers.
Xpider video is available on YouTube.

Product: down pressed clamp base.
Regards
Vladimir Kalmykov

Thanks for sharing, Vladimir!

I also have a 300-CS. How long did it take you to swap out the original base clamps and install these new ones and was it an easy process?

Had a look at the video and the base action is very nice...the lock/un-lock mechanism looks fast and easy. I especially like how the base lock releases when the clamp drops down. For those interested, video on YouTube is here:

Again, thanks for sharing!

Would you be willing to share how much they cost? Were the rails straight, or curved as in the video? I'm also curious about dimensions... but that might be an ask too far!

Took the words out of my mouth. I’m wondering if these would fit an Alpha Axis Pro...

Arvin_C · Jul 12, 2019

I've sent an inquiry out to Xpider to get pricing and purchasing info. Will also try Tourna support to see if they can order...AFAIK, Xpider does not have a US distributor.

Will post back if I hear anything...

Very interested in the outcome, as I'm also in the UK. You either have contacts or better googling skills than me to have found a UK supplier!

More like they told me haha! He doesn’t have the bases I. Stock as they’re super expensive. Has clamps. If you message me your email I can pass the details across.

ElMagoElGato · Jul 28, 2019

Looks cool. But looks expensive, too. I'll be much more interested if the price is around $100.

I'm thinking a set of them would probably be in the $300-$400 as the replacement lever-locking clamp bases for my machine (which Xpider makes for Tourna) would be about $200-$250 for a set. I will post what I learn once I get in touch with Xpider or the distributor.

Dags · Jul 28, 2019

With @MattCrosby 's intel, I called the UK supplier. He doesn't stock the base clamps because they'd be £350 a pair, which he thinks is crazy money. The conversation continued 'I've told them maybe £250, but even then...'. I did buy a pair of string clamps off him, and will write a review of those after dinner. Probably in another thread, because they're deserving of some attention.

I was curious about our OP's motive to create an account, make this thread and then abandon us, so did a little googling. He also posted in a badminton forum, and provided two further responses there. Apparently one of them contained a price before being edited: the claim is that he said $510 for the full set of base clamps, string clamps and rails.

Arvin_C · Jul 28, 2019

@Dags - Thanks for the info, Dags! $510 for the bases, string clamps and rails...steep, but I can see that price if you need to buy the string clamps and rails as well. Like you mentioned earlier, wonder if they have straight and curved rail sets available? I'm hoping since Xpider makes my machine, I'll be able to use these with no issues...

I’ll say. Ming!

Dags · Jul 28, 2019

Just as an afterthought - that £350 figure for the bases would include VAT @ 20%. The $510... who knows.

ElMagoElGato · Jul 28, 2019

I guess it’s a normal price for a quality cramp base. But still.

If my arithmetic is correct, a new set of Alpha gravity release bases (with new rails), and a new set of 5 tooth hybrid clamps...would run only $385.

Are you sure? That will fix all the annoyance on my machine.

Check out New tech tennis dot com. May have jumped the gun on that including new rails.

I can vouch for the clamps. Really nice. Didn’t spring for new bases, as mine appear to have some life left.

What machine do you have? Depending, not necessarily a given that the clamps and/or bases are interchangeable between brands.

Mine is Smart 909. It’s not much different from other models. The thickness of the rails could be a little unmatched for those bases. I can change rails all together of course while they are one of the concerns, too.

Hello all!

I just received an email from Ms. Wedny Chu at Xpider who confirmed that Tourna/Unique Sports should be able to order these clamp bases for us in the US. I have emailed Tourna and will update with pricing and ordering info once I hear back from them.

According to Ms. Chu, Xpider has a lot of demand for these clamp bases, with many owners of the Tourna 300-CS/Xpider Pro 690 having already purchased the base clamp kits.

Arvin C

Arvin_C · Jul 30, 2019

Just heard back from Mike from Tourna: They can order these base clamps from Xpider and that they are priced at $400 for the pair. They do not have them in yet as a stock product, but are ordering some sets to test on 300-CS and 600-ES machines. He also confirmed that these bases and their clamps now come as standard equipment on the Tourna 800-ES machine and that they are "quite nice".

Edited for clarification...

Unless all drawback has been removed gravity release clamp bases are a bad idea.

These clamp bases can be released three different ways: lifting up at the bottom end of the locking-lever, pressing down on the top end of the locking-lever or allowing the string clamp to release the base clamp when it lowers into the base clamp.

Aside from the actual mechanism of how this base clamp locks and releases, how is it less secure than the rotating lock usually found? Don’t I still only release the clamp once tension is applied and the other string clamp is secure?

Asking for clarification...Thanks!

You should always clamp the string first then lock the base without preloading the base so the tension is equal on both sides of the clamp, then you should be able to release tension on one side. So now after you weave the next string tension should the equal again on both sides of the clamp before you release the clamp so the string does not slip through the clamp. The only way to know for sure the pressure has equalized is to release the base first then the clamp. Especially with a LO machine the tension on the previously tensioned string could be a lot lower depending on how the machine is used, and maintained.

Rabbit · Aug 1, 2019

@Arvin_C, this is pure speculation on @Irvin's part. He's never used gravity release clamps and doesn't have them; therefore they are not desirable. I can tell you first hand that they are a boon to stringing as far as I'm concerned. They facilitate less movement on the stringer's part, work great and are in no way detrimental to the string. I have used mine on all types of string including natural gut. If they were such a bad idea, why are they now standard on all upper level machines? @Richard Parnell uses them on his Wilson Baiardo in the video where he demonstrates an ATW pattern. They are a great option on any machine, including lock outs.

Arvin_C · Aug 1, 2019

@Rabbit - Yes, was wondering if I just didn’t understand Irvin. I, myself, do not have experience with gravity-release bases, however I do know that Baiardo’s, Yonex Precision’s, Babolat Sensor/Racquet Station’s etc. all feature them as standard equipment. Figured with my intention to customize my machine to “pro” levels, might as well go all the way and get these along with the Wise...

Thanks!

Those types of machines are not lockout machines. When clamping, clamp the string first then lock the base. When you release the clamp, release the base first then the clamp.

Your "analysis" of lock out machines is pure speculation, and reasoning with faulty logic. Lockout machines would work perfectly with gravity release clamps. I can probably cite you 10 different things you've railed against that now you think are great.

It'd be pretty dadgum difficult to lock the base and then clamp the string. Yeah, I'd release the base first if I didn't have gravity clamps. But since I have gravity clamps, I release the clamp first and it handles releasing the base. It all depends on the tool set you have available.

Resurrecting this thread to share that these bases can now be purchased directly through Tourna/Unique Sports. The cost I was quoted was $225 each (ouch!). Still, I’m thinking about it. Any reason anyone could think of that these wouldn’t work on an Alpha Axis Pro?

Dimensions of the rails are a potential sticking point. Thickness is a critical dimension that can easily be overlooked - the bases have to be able to clamp sufficiently, and I don't know how much adjustment is allowed. Ideally, you'd find someone who has these bases and ask them ever so politely whether they could take all required readings...

And if you're buying the rails with them, it's of course whether you can fit those successfully on your turntable.

There's also possibly the diameter of the posts on your string clamps if you're keeping those.

Having expressed interest in these when they were first released - and they do still look like very nice base clamps - I think I've come to conclusion that I've probably got about as much value as I will out of my upgrades. My base machine is a RAB Stringmaster 1000, which as far as I can tell is pretty similar to your Axis Pro. I've fitted a Wise, replaced the string clamps, and upgraded the side supports. Sinking this sort of money into the bases feels a touch disproportionate, particularly as everything else is ageing. Next move will likely be a premium machine. I'd better get saving... (and I appreciate you didn't ask for opinions, but I figured it may help the thought process even if it were along the lines of 'That Dags is pretty clueless. Take my $450 and give me that sweet, sweet upgrade.'. In which case, I look forward to the review and whether it will change my fickle mind.)

Irvin · Jun 1, 2021

The rails for the Xpider are curved while the bases on the Axis Pro are straight (I believe.) Not sure if the Axis Pro will mount the Xpider rails or if there is a wider enough track below the rails on the Axis Pro for it to work. I have sent a message to Mark to find out for sure, if he knows.

am1899 · Jun 1, 2021

Thanks @Dags. Indeed, your thoughts were along the lines of what had crossed my mind. And I did consider that, at $450...that’s certainly a large chunk of change and not an unsubstantial fraction of what it would cost to purchase a flagship machine - from a few mfg’s anyway. My mind is certainly not made up.

Thanks @Irvin. Sounds like some folks with the Tourna 300-CS have gone ahead with this upgrade, so I’m at least slightly at ease that curved rails are not a requirement. But obviously don’t know if there are other dimension differences that might be an impediment. I did see a video on YT where a gentlemen installed these on a Gamma turntable...which is interesting, and perhaps hints that there may be some measure of versatility across some, but not necessarily all brands. Interested to hear Mark’s thoughts.

Irvin · Jun 1, 2021

Mark just replied. He does not think the Xpider bases will work on the AP but he did not know for sure. If you want me to make any measurements I can. I also asked if the AP clamps would work on the Xpider bases. They must not only be the same diameter they must be the right length for the gravity release to work if you’ll be using gravity release. Mark said usually their specs are different.

Got it, thanks @Irvin! I think then I’ll pass on these. But maybe they’ll work for someone else with a different machine.

Can you post a link to the Gamma vid you speak of? Interested, but not likely to pull the trigger. Thx

Irvin · Jun 2, 2021

@am1899 Those bases may fit on a Gamma turntable but the turntable is not going to be as stiff and the rails on the Xpider bases. On my machine the turntable is over 1/4" thick and the rails about 1'4" thick so the 2 together are over 1/2" thick.

Also Mark mentioned that Alpha also had gravity release bases the AP clamps would work with.

It does seem like, in the video, he’s able to make some adjustments to get them working. But how well they work on the Gamma turntable vs the turntable(s) the bases were designed for, I suppose is anybody’s guess. I’m still curious if they would work on my machine. But I don’t know that I’m curious enough to take a $450 flyer to find out. I suppose I could buy 1 to test it out. But even then, if it doesn’t work, I’d have myself a $225 paper weight.

Yes I’ve also seen the Alpha gravity release bases Mark is referring to. They seem pretty nice, but to me the Xpider units seem even nicer. To be fair, I think the differences are reflected in the difference in price between the 2 units - the Xpider units being almost double the cost of the Alphas.

Either way, my bases are now requiring a lot more frequent cleaning and adjustment to keep them operational. Which is why I’ve been looking into replacement units of late.

Irvin · Jun 2, 2021

@am1899 if you decide to try them out, I have a contact that may be able to get wholesale pricing.

the_faceless_player · Jun 2, 2021

@am1899 - I have an Axis Pro as well and the Alpha Gravity Release bases are a huge upgrade over the ones that come stock on the machine. It's not even necessarily about the gravity release feature. The locking mechanism is just faster and easier to use, allowing for one handed control of the clamps and has sped up my string jobs for sure. The Xpider ones look awesome but are definitely a gamble for that kind of money based on the questionable compatibility. I've upgraded several things on my AP and going to the other Alpha bases was probably the best upgrade. Would definitely recommend them if you're shopping for new ones.

Thanks guys.

brownbearfalling · Jul 17, 2022

Anyone have updates on successfully buying the clamp bases? Or did bought the whole Tourna machine?

the_faceless_player · Jul 17, 2022

I bought a Stringmaster Deluxe from Germany back in February. Same table and clamp setup as the Tourna 700 but it uses the Wise I already had so was significantly cheaper. The table, clamps and Xpider bases are miles better than my Axis Pro, even with all the upgrades I had done. I’d agree with others that the Tourna/Stringmaster table spins a little too freely but otherwise it’s been a fantastic setup for me

USMC-615 · Jul 18, 2022

Have a new Tourna 350-CS and might be looking into a set of these Xpider bases. Wouldn't mind getting a set for my Gamma Progression ST II as well if they'll fit the turntable track thickness and clamp correctly (thickness adjustment?).

stringtheory · Aug 15, 2022

Hi, able to share which is the exact model you bought? I am looking at purchasing one as well

Was going to get it with a new Wise so I could sell my current one with my old machine but they said it would be so expensive to ship to US that they would not do it. They shipped me the machine without the Wise and adjusted the price. After I sold my crank LO, it ended up being like a $300 upgrade for me which was well worth it

I’m looking to get the same machine as well but I’m based in Asia so shipping will be a problem

What was the process u went through with them? Did you email them to quote a shipping fee for u? Or did you just input yr shipping address in the website and just checked out from there

i placed the order and they flagged my shipping address and reached out. We discussed options and they adjusted the order to reflect the removal of the Wise and updated the price. One note, they did not include the required mounting plate after removing the Wise even though I still needed it for my existing Wise. They didnt tell me it wouldn’t be included and I ended up having to buy one from TW. They never responded to my request to be credited for the cost of the plate.
