Tecnifibre Triax 16 -- a long-range review

If I can summarize my experience with Triax it would be -- it is like a natural gut but with a spin potential of a soft poly like Hyper-G soft.

I have been playing with Tecnifibre Triax 16 full-bed in my 360+ Radical MPs for two years now, and it has been the most gratifying experience.

I started using Triax as a "cheap" substitute in my Clash 98 for the natural gut. I played with natural gut in my primary Clash 98 at the time because it came with it, and I kept natural gut in it to heal my arm.
I discovered Triax after watching Tennis Spin review of it, and I decided to give it a try in my backup Clash 98 because it was a far more affordable option for me. Honestly, it was hard to tell the difference between the Luxilon natural gut at 60 and the Triax at 55.

In late 2021, I switched to Radical MP, and I re-strung it with Triax (16) because the polys in it (Lynx) would always aggravate my arm.
I had to experiment with the tension until I settled at 55, which was comfortable enough while helping me retain control and have enough access to spin.

After over two years of playing, here are is the summary of impressions and my pros and cons of this string:

Overall impressions:

Tecnifibre Triax is a wonderfully comfortable string, almost on par with natural gut. Its spin potential is very good, and it is on par with the soft polys (also corroborated by the TWU measurements).
The string has been very durable for me -- it lasts me four to six months (My pro stringer re-strings it when the stringbed tension drops below the recommended level and as measured by the stringbed stiffness machine. YES: we use that machine to measure how much stiffness/elasticity is left to gauge the right time to re-string).
The feel of Triax is great for me. Note that the string is not springy and crisp as poly. It feels "gummier" but also far more comfortable than a typical poly. The launch angle is lower than Lynx Tour 17 or Hyper-G 17 soft. Triax has great ball pocketing. As I said in the opening statement, it is like a natural gut but with a much higher spin potential.
The string is comfortable and medium firm, with a somewhat dampened feel. It took me some time to adjust from Hyper-G, but my arm was very happy. Never had an arm issue with it.

My current profile (1/2023):
I am an ambitious but "normal" recreational player. My technique level is around 4.0, as assessed by multiple pros, and I am progressing. I hit semi-hard, emphasizing depth and control through some form of spin. I play 4-7 times a week, hard surface and clay, every month of the year, indoors and outdoors. I play with 3.0 - 4.5 players, and I hit against the tennis ball machine regularly.

Pros:
Total arm safety and comfort
Spin for the string of this type (multi/fusion), or compared to Hyper G soft or Luxilon Element. I can generate plenty of spin with it, and never felt like I have an issue with it.
Ball pocketing feel
Control -- for the string of this type. Stays much more controllable over time than polys or other multis.

Cons:
MSRP, although I buy from my (pro) stringer, and I get a great price on it. Just a few $ above velocity or hyper-g, strung.
Rubbery feel on contact - it has a bit of a rubbery feel when compared to Velocity, although I am used to it, so I cannot tell anymore.
Less spin potential than Lynx Tour or Hyper-G, which is, for me, the magic ball-biting spin maker

Playing experience with other strings:
Hyper-G 16L/17 -- love it. A league on its own. Cannot be really compared to Triax
Hyper-G soft 17 -- not impressed and not worth it vs. Triax. Similar/lower spin potential
Velocity MLT 16/17 -- great string, but it feels stiffer than Triax. It breaks in the frame after ongoing use whereas Triax lasts.
Lynx Tour 17 -- I like it a lot. Cannot be really compared to Triax
Sonic Pro -- I like it with low tension. Hard to control when it loses tension and it loses tension quickly. It still feels great but you have to rein it in.
Luxilon Element -- I like it a lot. Feels great, but it loses tension so quickly that it becomes hard to control.
Lynx 17/Velocity 17 at 52 -- not as comfortable as Triax. Stiffer when strung. Not nearly as comfortable nor arm-safe as Triax.
Wilson Synthetic Gut 17 - not that dissimilar. It does not last nearly as long and it does not have the same string potential

And here are the pictures of full bed Triax in my two frames after 2-3 sessions of 1-1.5 hours of pretty good hitting with each.
Each of the sessions had lots of top spin shots, lots of slices, lots of serves.
The strings were strung at 55 lbs about three weeks ago and in a full bed.
Right after stringing, they measured around 60 on the room temperature on Tourna stringmeter.
Today, they measured around 58 and in the same conditions.

Notice no fraying. Strings maintain the pretty lively snap back.

great review.
somebody can compare Triax and Duramix "new" HD? they are very similar on tecnifibre website, but, no many peaple compare them..
 
Nice review! Have you found any other multi that its performance comes close to triax?
In addition to those I listed (MLT), I played with Wilson multis (NXT) in a hybrid, but I could not tell enough. It was Wilson’s hybrid control package.

I ordered TF RPX and Tourna Silver 16, to hybrid it so we’ll see how that goes. RPX is supposed to be almost identical. Just $5-7 cheaper per set.

Thanks for review. Do you compare Triax to Gut/Poly or FB Gut?

Good question -- it is more in between the two. It definitely has the pocketing and elasticity that reminds me of gut, but it is better on spin. Snaps back. It is stiffer than gut on the spin.
On the other hand, it is more elastic than a hybrid setup, at least before the poly in a hybrid loosens up significantly.

Fresh Triax vs Gut/Poly and spin for me is about the same. After some hits Triax spin decreases, but Gut/Poly stay about the same, maybe little less.
 
A quick update -- I strung one of my Radicals with a hybrid of RPX 16@55 in the mains and Tourna BH Silver 16@52 in the crosses, and the experience is great so far.
I still get an arm/shoulder comfort of Triax, but I get a crisper more precise feeling with this hybrid and a really nice spin -- both on a serve and on groundstrokes.

I expect that Triax 16 with Tourna Silver 16 would play about the same, because I cannot really tell the difference between Triax and RPX, at least not on touch.

I tried Triax 1.28 FB on yonex vcore100(2023). Compated to X-one 1.25, triax has more spin potential and control, and little bit less comfort. I really liked this string. If the coating lasts more than 16hrs and string movement will not happened, this string will be my go to string.
 
Hmm, OP, have you tried Multifeel Black? That's my go-to string, though I hybrid it instead of playing it full bed. It's got a little more spin potential, energy return, and tension maintenance looking at TWU.

I have not. Thanks for the recommendation. Will check it out.

Btw - RPX mains, Tourna Silver 16 crosses is a fantastic hybrid.

Have you tried a fullbed of Volkl Cyclone Tour 16g? Spin is A++ and comfort is also A++ for a poly, 167 stiffness rating compared to 162 for Triax 16.

@Maloya,

Duramix came out in 2011 and I think it is a second-generation mulityester. Seem HDMX, RPX and Triax are third generation multesters.

Tecnifibre has been cross-breeding multis with polys since at least 2003, 20 years and probably longer. I've termed them mulityesters and there are several companies now in this market but Technibre IMO is the one company pushing this new type of string more than the others. Wilson's NXT Control (made by Tecnibre) was launched in 2011 and saw more success than Duramix. Yonex Rexis Speed is Yonex's version of a multiester.

I was on the playtest from both Wilson and from TW of Wilson NXT Control. Two separate playtests. Then Tecnibre created HDX Tour in 2014. NXT Control and HDX Tour were both far more successful than Duramix. Duramix was a string I never found a groove with, yet both NXT Control and HDX Tour felt more like X1 Bi-Phase with a longer shelf-life. HDX Tour never came in a reel (only 20-pack boxes) and was replaced around 2019 by day-glow HDMX which started coming out in reels and packs.

Enter Triax. If you buy on sale like the one that just ended March 20 (Buy 3 get one free) in the thickest 1.38mm (15L) version or buy a reel on sale and use eight 27" frame lengths on a 16M 100 square frame you can get 36 sets of mains out of a reel if you bridge the main tie offs. I have strung a lot of 1.38mm Triax for a few 4.5C-rated USTA men in their 40s with elbow issues. I created a thread about my solution for these type of players if you get bored.


Here are some interesting links that pertain to your initial question.

If you haven't listened to this podcast, it is most informative. The discussion with Jonathon, JDub / Wolfman (TW string guru), Kristen, and Julie is a great listen for stringers like me.



"Promix had 30 percent polyester and 70 percent polyamide microfibers, and X-Code has 100 percent polyester microfibers, Duramix HD has 50 percent polyester and 50 percent polyamide microfibers."

For anyone not already aware, Technibre makes NXT. Wilson markets it in their red and white packaging, but they most certainly don't make it.

Finally settled on a hybrid of Triax and Multifeel Black (56/54) after trying various combinations of VS Touch, Triax and Multifeel Black. For me it's an effective balance of arm comfort (biggest priority), spin, minimal string movement and tension maintenance. The two fray up, but I live with it.

Thanks for the suggestion. I have not because 52% percent tension loss turned me off. It is one of the highest of all strings, that I know. The same applies to the Element which I like a lot but the tension loss is just too high for me (44%).

I get about 8 hours out of it before I notice the tension lose is too much but then I string it at 19kgs. If you string it a little higher than your usual I am sure it'll stay at a tension you'll like once it settles.

Just a suggestion:

Stop looking at all the TW numbers and hit with a string before judging it.

I string a 1000+ frames a year and wrritten extensively about VCT 1.30 posting names, USTA records, and frames & tension of 4.5 and 5,0 USTA actual C rated players who have used VCT 1.30mm for 10+ years. I have 30 plus reels of polys and string as much VCT 1.30 as I string HG 1.25mm

Been posting on this forum since 2009 and 98% of my posts are about strings that I've actually strung and hit with in my own frames. Hitting with a full bed of a string is the only way for me to fully evaluate a string before I recommend it to a client. And I stand behind my blind playtest for 100% of my clients.

Thanks for the suggestion, but it would be a bit antithetical to who I am to "stop looking into numbers".

I am a practicing scientist with long experience, so I don't just "stop" looking at the numbers. In fact, I cannot express enough how much I admire @TW Staff and @TW Professor for the effort, discipline, and rigor they put into the testing process.

I read all the TWU papers and articles, and I have to say that I am beyond impressed with their methods and experiments.

Further, I find that their experiments and numbers match my experience, so I am even more impressed and convinced.

So my view is that one should look even harder into (reliably produced) numbers.

Have you ever considered removing bias as a practicing scientist? Isn't that what science is supposed to do? :unsure:

You've got a head full of bias. Blind playtest remove that bias. Many lower-level players on this forum dismiss strings due to data yet the actual players who have the 4.5C and 5.0C rating win at a high level with lines lower-level players dismiss as unsuitable for their game. There are thousands of players who start playing tennis and think they are 4.0 or 4.5 players based on USTA rating guidelines.

Is this accurate? You've been playing tennis for slightly more than 2 years? If so, your post is much clearer now.

After over two years of playing, here are is the summary of impressions and my pros and cons of this string:

My current profile (1/2023):
I am an ambitious but "normal" recreational player. My technique level is around 4.0, as assessed by multiple pros, and I am progressing. I hit semi-hard, emphasizing depth and control through some form of spin. I play 4-7 times a week, hard surface and clay, every month of the year, indoors and outdoors. I play with 3.0 - 4.5 players, and I hit against the tennis ball machine regularly.

Playing experience with other strings:
Hyper-G 16L/17 -- love it. A league on its own. Cannot be really compared to Triax
Hyper-G soft 17 -- not impressed and not worth it vs. Triax. Similar/lower spin potential

And somehow you make the assumption that posters like me on this site don't read or comprehend the data. :unsure: That's quite an assumption.

Thanks for expressing your views and recommendations. I have some alternative suggestions, which perhaps have more to do with the style.

I would look into the style of communication and writing that could be taken as patronizing ("stop looking into numbers") and presumptuous ("you make an assumption").

I have not made any assumptions -- about you or anybody else. I share my experiences, viewpoints, and observations. I do not tell you or anybody else what to do or not to do, what they think or know. Note the careful use of "one" vs. "you", all to avoid any notion of ad hominem style of argument.

In fact, I speak only in my own name and express my own experiences, views, and philosophies. I don't presume anything; I am not here to tell others what they know and what they don't know, what they should do -- this is probably the basic courtesy of a good argument and the politeness is speech.

Nice thread thanks for posting the review! I'm currently trying to play through contuining elbow twinges and I got a Prince phantom 100x 305g as I love control rackets, strung it up with Velocity 16g/Cream at 24/23 grams. This feels pretty low powered and muted to me, would triax be a crisper option?
Is cream in the cross expanding snapback and spin over lifetime for triax as it would with velocity? A locked string bed is the worst, especially when your string is as expensive as triax, and then need to cut it out.

ogsm (syn gut) is a cheaper and crisper option that has decent power. if your elbow is painful, though, i would recommend avoiding poly altogether until pain subsides.

I absolutely get why poly is a problem in this case it is just very hard as a nearly lifelong poly player... My hope was velocity or V/Cream is a solution but in my opinion or for my game it is not working, not enough feel and spin potential. Hence my question on Triax (or HDMX) as alternative :).
My try with syn gut was not a big pleasure, string bed can be locked quickly I feel.

I have found notched mains to continue sliding over cream rather than locking, but ymmv. i doubt you will find a major difference in spin with fb triax vs full bed velocity, but you will prob get some more feel vs velocity. others may have had different experiences. good luck!
 
what about weight of Tecnifibre Triax 1.33 for example? How does it compare to regular 1.25 poly strings?

It's heavier or lighter than 1.25 co-poly? How many SW points does 1.33 Triax add to a regular 98" 16/19 racket?

I have not but I noticed that after Triax stretches in the frame, it just gets better at grabbing the tennis ball. It does not turn into a trampoline.
