They should make an unexpected move and set the maximum tire clearance to 35 or 38 🤯
What's the betting they ditch the wiggly fork steerer.

Well, the question is, do they actually make these frames? same was said of the X68.
Those images may well be from the factory that is in fact making the current bike that numerous sellers are currently selling, and those bikes do not have the wiggly fork but they have attempted something!

That would be both peak trolling and peak smart. Hell I'd consider buying one if it could run the gp5000 in 35c. That and positive stack cockpit.
They could advertise as "we just released the SL11. Sucka".
Edit: as per Pistonbroke early Oct26, clearance is in fact suitable for GP5000 35C. see my post from Oct 7th 2026. Reply #67

Holy shit, with that steerer tube, it's safe to expect issues...
Also @Serge_K is it a fake when it has another bottom bracket standard?
Thing that bums me out about Tantan is they have the capacity to really innovate and offer good stuff at a decent price.
I have one of their Cervelo R5 clones (FM239 I think). Mirrors old R5 geometry to the tee. Barely fits a 28c tire. They have a super interesting updated version called the FM231. The geometry is actually pretty crazy. The size closest to my current one gets 7mm more stack but like 25mm more reach. And it fits a 32c minimum. Given that I run a 130mm stem that extra reach would be appreciated. But you have to be a geometry chart dweeb like me to even notice something like this. They would rather just hawk Tarmac/Factor clones. Big missed opportunity
Looks great!
T47 BB is great!
I've got the TT65 from Tantan that's my pride n joy so trust this will be good too hopefully. I'll recommend this to a friend who's recently become China curious in terms of bikes wink
Post 2125 in the x68 thread.
They're calling it the new x68.
Obvious sl9 clone but t47.
Hopefully we'll be able to get the zero posts somewhere for our x68's-I want the new style but would never spend the crazy S brand $$

Just came here to say TanTan is just a reseller and uses the same frames as the better counterfeit sellers. Maybe I need to upgrade lol

I thought this was quite interesting.
I've been speaking to someone in China who is not connected with TanTan, but who is involved in bringing a frame to market.
According to him, his frame comes from the same factory that produces the TanTan frame. I can't independently verify that, so take it as information I've been given rather than confirmed fact.
He also explained that one of the main reasons factories are producing these popular "inspired" frames is because the market is so slow at the moment. Popular designs generate orders, the factory owner is under pressure to get orders and the frame helps keep production lines running and keeps factory workers employed.

I believe those use the old "Richey" style clamp that the original sl8 zero used. I don't want that. The sl9 zero uses the same style clamp as the 15 and has the same aero profile.
Hi
Maybe old info, but anyway. I just got reply for "New X68" :
The mold for the new version of the TT-X68 frame is still being manufactured.
We need to wait for the sample frame to pass the test before we can start producing the frame and start selling it.
It is expected to be September-October.
We only have 3D pictures and no pictures of the actual frame yet.
TT-X68 new will be in sizes: 49/52/54/56/58/61cm (it is not sure whether the mold will be opened for all frame sizes now)
Hey everyone
Some photos and a geometry chart for the updated X68
Looks like 35c clearance but I have been told this is provisional and the BB is T47
Photos is a 54cm which will be the first size for sale with the shortest lead time when it becomes available, good job as 54cm is my size ;D
No Ideas what frame sizes they will be offering as was told
"Regarding the full range of sizes, nothing has been finalized yet; we will make a decision based on market demand and sales performance"Price
"As for the price, it should be the same as that of the TT-X68" which is good to here!

How many months till we see first BB sleeve debonding issue? ;D ;D
35 days to be exact.
BB deboning can happen on any bike I have seen it on the big brands but obviously it may get handled better but for £500 its throw away so worth a punt IMO. Geo chart saying 35c for clearance but this is still TBC
INFO:
The mold production sequence for the frames is: 54 → 56 → 52 → 49 → 58 → 61 cm.
Molds for the 54, 56, and 52 cm sizes are currently in production.
Orders are expected to open in 30 days, with shipping scheduled for October or November.
This time, I have to disagree with you 😢😁. I'm not necessarily criticizing the fact that the bottom bracket comes loose on such a cheap frame (though that shouldn't happen), but what I find unacceptable is Tantan's complete lack of respect for the consumer. They don't hesitate to ghost people, and I don't appreciate that at all.
Are there any photos of the steerer tube?
Ugh. I dont want a Tarmac clone, but this ticks so many boxes. Thankful for the LTK-266-D-SL
Aint No Ballerina!
54cm Frame 893.6g
They have chunked out fork! 440.9g no wiggle steerer so im assuming has same X68 headtube and not slimmed down like SL9.
My X68 forks were 399g and 54cm frame was 798G
I am actually relieved they kept the steerer straight, I think there is a lot of room for something to go wrong with the wonky steerer and I would prefer tantan to stay out of it.

Not keen to get something this time round, that looks the same as the SL9.
I'm eyeing up the Lightcarbon LCR20D, I asked about ordering it but was told they are a couple more months away from production and there new riser bars are still being tested.
Bike no 3 will be like the X68 I had for winter ;D. Aero winter bike won't look great with mudguards though 😂

I went ahead and ordered the LTK-266-D-SL. Im riding a clone now (Cervelo R5) but the Tarmac SLx stuff is just a bridge too far for me. 266 ticks all the same boxes w/o the stigma.
for winter riding, if one likes big tyres and stiff frames, and modern geometries (high stack), and Pinarello looks, Peter's grevil clone feels very much like a stiff AF road bike. I've done a dozen rides in the mountains with thousands in elevation w it in the past couple of weeks, i'm constantly thinking "man this is stiff" but never am i thinking "i wish i were on a road bike". As far as i can tell, if feels like a road bike that takes 50 or 55C. I miss my Tractor because of the comfort, but this faux grevil is very snappy out of the saddle, reminiscent of 25mm rim brake bikes. I have a 28C front and 32C rear, and it is stiiiiiiff. Today i rode a friend's Cervelo Caledonia, this thing is smooth and fast. The faux grevil is plenty fast, maybe faster, but not smooth :D It kind of feels like a Lambo. Some positively love it, i am very unsure myself, and absolutely not my idea of a daily driver.

I just had a crash with the old X68 and the top tube was damaged.
So I'm looking for the new X68.
TT approved the seat post will stay the same.
What I'm wondering is the weight increase of the frame.
My old one in 54 was about 770g.
I found pictures on the TT side of 837g and 984g on the Seraph side (all without paintwork).
Makes me a bit nervous.
Does someone received his frame and can state the real weight?
Thank you
I'll weigh and measure when it pitches up, but it'll be a 56.
I will be absolutely made up and pmsl if it fits my 35mm gp5k :)

The new X68 has gained quite a bit of weight 🐷 .
From what I've dug up, for a size 56, it has gained approximately:
frame: ~100g
fork: ~40g+
seatpost: ~40g... so that's not insignificant (at least in my book 🤷♂️).
Size 56 (frame, fork, seatpost, handlebar) with a glossy UD finish ends up weighing around 2000g 🤯 ...they definitely shouldn't be calling it "lightweight" anymore.
It was at the top of my list for a new bike, but unfortunately, it's dropping lower in the rankings by the day.
What is your current favourite?
anyone asked the sellers why the weight increased? Is it because they're cheaping out on fibers, and cheaper fibers weigh more, or is it them adding carbon because frames were breaking? The exploding fork(s) is something that had not been seen in years in Chinese carbon stuff. The risk of "will my frame disintegrate from under me" was no longer a fear, and then that brought it back.
I've asked Rose, will let you know :)
And my frame is on the way 8)
You can also have what Gemini surmised about the weight gain...
The updated X68 revision incorporates design cues reflecting the Tarmac SL9 frame styling. Visually, this means broader aero profiles around the head tube junction, deeper fork legs, and slightly filled-in fairings around the seat tube/bottom bracket area to improve wind-tunnel efficiency.
1. Fork & Front-End Structural Reinforcement
On early iterations of the SL8-style X68, users and testers noted that the forks were pushed to dangerous sub-340g limits with very thin carbon layups. Following safety feedback, manufacturers increased the wall thickness of the steerer tube and fork blades—bumping uncut fork weights from ~340g to ~415g+ alone. Added carbon around the deeper head tube junction contributes a significant chunk of that extra weight.
2. UDH Dropouts & Metal Hardware Inserts
Transitioning the rear triangle to accommodate a true SRAM UDH (Universal Derailleur Hanger) spec requires a much beefier, denser carbon structure around the drive-side dropout, along with heavier aluminum insert hardware to support high-torque derailleur mounting.
3. Increased Surface Area (Deeper Aero Profiles)
To mimic the SL9's refined aerodynamics, tube profiles around the top of the down tube, bottom bracket junction, and seat post collar were widened. More surface area naturally requires more carbon cloth and resin to wrap the mold.
4. Manufacturing Safety Margins (Wall Thickness)
Mass-producing ultra-light ~800g frames with cheaper T700/T800 carbon grades leaves zero room for error. Open-mold factories frequently add extra resin and structural layers after initial production runs to lower warranty claim rates, prevent frame cracking around the bottom bracket, and ensure pass marks on ISO impact tests.

The specs say it uses full T1000 carbon 🤣 but yeah... If that were really the case, the bike wouldn't weigh as much as an elephant.

Wasn't there some Chinese brand basically saying that they're all "using T1000" but actually nobody is really using that? Most frames are layed up with T700/T800 regardless of what the spec sheet says.
Edit: Just adding to that: The manufacturer of the frames (Long Teng) states that the frames are all T800 Carbon, while Mondince claim it's T1000. TanTan at least on the GR201 claims T800 + T1000, maybe T1000 for the handlebars, not sure.
Is the headset compatible with FSA ACR? I'm considering mounting an HBR 017 on it.

No frame is 100% T1000, someone in some thread around here pointed out the frame would be too brittle.
My frame is currently clearing customs, so barring any delivery catastrophes I should have it next week....

Afaik, T700 is the backbone of almost all frames. I think you can replace that with some Mxx fiber because it sounds fancier. But T700 is the backbone. Then if you spend a bit more, you include a fair bit of T800. Then fancy more, you add super fancy fibers like T1000 / T1100, which are often called high modulus. T800 probably costs 40-100% more than T700, then T1000 is probably 100-150% more than T800, something like that. You probably get 10-20% of T1000 max in a frame, beyond that it's brittle AF. Sworks frames are known to crack when you put them in your trunk because they have a lot of such fibers, it's not really a blessing unless you weigh 60kg and are super strong.
Very few advertise the 700 aspect of things because it sounds ghetto and it's kind of implied. If you market 800, it means you use more than just 700. And so on. Kind of like a cocktail that you water down, you dont advertise the water, it's implied.
At least, that's my read of it.
For cockpits, idk. I suspect it's largely the same idea, because a full T1000 cockpit would probably be horrendous for several reasons. But maybe the core is 800, for eg, i just dont know.

Hi folks
It's all looking good and going together very easily.
Hoses and cables threaded really easily.
Faced the brake bosses but it was only a little paint really, nothing drastic.
The only thing that hasn't worked for me is the bars. They are lovely and really well finished but because I'm going to run 1x mechanical (yup, I'm a luddite!)the transition curve from headset to bars is too tight. With bars that integrate the cable internally it's fine so I'm just going to fudge the top cap for now.
Special mention to the headset compression ring, it's a great design and well executed.... Very reminiscent of an original specialized.
Popped a seat on today too. The post is nice, but the folks at the factory could shave fifteen or twenty grams off it by making the top and bottom cradles from carbon.... And I'd happily pay an uplift for that.
The other piccy is in case anyone else is daft enough to run mechanical. It's an easy bodge that cleans up the cable run from the frame to the rear mech. V brake noodle ( if you're old enough to remember them :-) ) and an online cable adjuster.
With a little luck I'll get it up and running for the weekend and report back, but it's looking really good so far!

love the idea. the way the cable exits the frame this is a really really good solution.
i got an old MTB standing around which runs a V brake noodle. if you ever need a spare one ... 8) ;D
Thanks, appreciate it!
Ok, we're ready for a spin tomorrow.
Build has been very straightforward. Thumbs up to the factory!
Excuse the cockpit, I need to work out reach then I'll get some integrated bars.

Front tyre is 33wam with easy 8mm either side.
So, for future reference, this frame clears 37.7m+3+3mm at the back, and 33+8+8 at the front (or 42+3.5+3.5 front)
So, one could argue, it takes an aero front wheel with a conti gp5000 35C on optimized rim (40-42 wide rim), and a non aero optimized conti gp5000 35C at the back (Pistonbroke is running a 26 internal, 33 ext rear wheel).
It's suboptimal at the rear (but the rear matters a lot less than the front aero wise), but in Oct 2026, it's far from being bad. Not too many frames that offer "real" 35C clearance.
All sounds about right :)

I dont suspect that you were able to measure how much wider the head tube is on this vs the SL9, right? the wonkey steerer on the spesh let them use a narrower headtube, afaik. This is probably worth a handful of watts at 45kmh. would be curious to know how the frame looks side by side vs a real one. The downtube looks super uninspired, it's a bit of a mystery to me how spesh manages to make fast frames while looking brick-aero.
My favourite AI thinks an SL9 is 41-43mm but you'll have to ask Stephen :)
Sounds possible.

Build has been very straightforward. Thumbs up to the factory!
Excuse the cockpit, I need to work out reach then I'll get some integrated bars.
Rear tyre is 35mm gp5k. Reiterating 3mm clearance either side at the chainstays. Will keep an eye for witness marks.
Did you weigh it by any chance?
Sure.
Frame etc weights above
Bike weighs about 7.7kgs
If I put components from my other whip on it would weigh 6.4kgs :-)
Ok folks..... Just done 35k shakedown.
At the risk of being torpedoed by Patty's far more experienced and professional review later on....I think this is a damn good bike.
Nothing went wrong.
It's fast and comfortable. The comfortable may be the 35mm tyre of course.
Handles as you would expect.
I topped out at 65kph and it was perfectly stable.
No tyre witness marks on chainstays.
My sprint isn't going to trouble anyone, low four figures, but it didn't feel like it was being wasted.
Ride was blind so RPE, computer in back pocket, pulled some surprise PB's. I know it doesn't mean anything :-)
Will add to this as things pop in my head.
Look forward to other people's thoughts!
This is worth listening to. I fully appreciate this isn't an SL9, but it's a great look at the reason they designed it the way they have.

Went out again today.
Rock solid.
Still think it's fast, comfortable and puts the power down well.
Took a 10% hill climb kom/5000
Very happy with it :-)

Between this and the Light Cycling RF10 it seems we are starting to see brands take their $500-$700 frames more seriously. More solid options in this price range means more customers who are Chinese brand curious can dabble without the huge price tag.
I'm curious though what exactly has shifted. Has both production and QC improved on behalf of the factories? More pushback from the brand owners themselves to make a better product? Either way, I'm here for it.
Well... Here's hoping you feel the same way about it buddy :o :)
Is the front brake adapter the same as SL8/old X68 or the Standard Flat Mount adapter
I put a standard Shimano flat mount on :)
Brother had a bash on it today.
He's 6'4 and 115kgs so a bit small for him, lol! He thought it felt stiff and put power down well too, so hopefully I wasn't imagining it.
Thinking of selling my specialized because this is really good :o
ETA
I'm gagging to hear someone else's thoughts :)

It annoys me that 1. i really dont like the looks of the SL8/SL9 2. the SL8/SL9 is objectively an excellent bike and 3. Tantan actually makes good clones when they dont ship lemons.
It's extremely annoying :D
Incoming... ;D
Nice-pantone colour?

Looks like the fork is more deeper than lightcycling rf10. If general consensus is good, i might just get frame instead of wait for Tagoola's frame development
i ordered mine on 6. this month, cant wait to get my hands on it ;D
i will aim for a chinese parts only build, except the tires

You mean that you will avoid buying chinese bike parts rebranded by Western companies on your build :p

So can't wait to comparison this one to RF10, is there any ETA?

They are the same, I can tell you that.

what makes you think that?

Just check the geometry charts between X68, R099 and RF10, they are identical.

And here I thought they were mad at you...
Wish someone would clone the new zero offset post.

I would disagree with that. IMO, the R099 and RF10 are identical. TanTan has a different headset area. The "X68 New" fork is also very different in shape (looks sturdier and is heavier on paper).

I stand corrected. Yes, the TanTan is more of a SL8 (front) and SL9 (rear) hybrid, with slightly wider fork. However the geometry 99% identical to the other two frames.
I wonder if the frame design has improved much? If not, it's just more weight. Also I don't see T47 much of an improvement, more like a headache with those narrow lip threads. They're a PITA to tighten without slippage.
Well I didn't have the original x68 but did have the r088.
Keep in mind that I'm probably talking absolute bollox :) , and I'm not a seasoned reviewer like Patty but this is what I think so far...
It's stiffer. Could be the larger BB area perhaps, but feels(probably the most important word, lol) like it puts your power to good use.
It's comfortable even with the bigger forks (these are a very different design) Better tyre clearance too.
I reckon it's a bit faster. I'm using power pedals and often ride the same routes and think it's a touch under a kph faster. Tiny amount for sure, and again, I'm probably full of it ;)
I don't mind a t47 either, I think it's mostly down to the tool.... Which could be me lolz.
Patty's review is so going to sink me ::) :)
Park's Tool T47 bottom bracket...tool is fantastic. No issues with installing or removing T47 BBs. But there is a certain level of finesse to preventing tool slip or scratching the frame. A pro tip is I usually only torque each cup to around 30-35Nm. Rather than the recommended 40-50Nm of some threaded BBs. And I use a mechanic stand for good leverage.
These days I have basically have zero patience for seat post slippage. No matter how much or little a frameset costs. If the seat post and wedge are solid and the headset bearings seat well into the head tube cups, everything else I can deal with.
This new X68 update just need not be a noodle under load. And all the parts and components fit together nicely without creaks or rattles. If TanTan can nail this I will be satisfied. The design itself has already been proven.

I have two T47 framesets and two threaded BSA framesets. All four frames are running 165mm length cranks and 24mm titanium axles. I can't tell the difference in performance on hard sprints or uphill grinds. The biggest difference I felt was switching to lightweight carbon spoke wheels which increased my average watts and sprint speeds.
Agree-ish :)
Lightweight wheels are an absolute joy, no doubt. Would recommend them to anyone first.
I thought the frame felt stiffer than my Spec and the R088. Can't put my finger on as to why, so then I hand it to the brute squad for a second opinion.
He's 120kg and around 1400w seated :o #jealous.
He thought it felt stiffer. I've got nothing more than that. Just our humble opinion, certainly not gospel and not spoiling for a fight :)

I probably don't weigh enough and definitely don't pull that kind of wattage! lol
It does make me wonder if internally threaded T47 is superior in regards to stiffness. I'd much prefer external T47 cups for better tool placement, but many frame manufacturers are opting to go internal instead. :(
I actually spoke about this subject, and why I prefer BB86 and T47 inboard, in a thread back in February
https://chinertown.com/index.php/topic,6990.0.html
From
@toxin "From an engineering standpoint, yes BB86, 386EVO are better. If anything BB30 and BBRight directfit could even be considered superior, because the bearings are pressed directly into the frame, with no cups. The best would be dimensioned similar to 386EVO with the bearings pressed directly into the frame like BB30.
But that's in an ideal world. The reality is that the majority of the bike industry has simply proven too unreliable to consistently produce such standards to spec, so we're back to threaded. T47I is the closest compromise in that regard.
Personally I'm not a huge believer in driving stiffness. Humans are far too weak for there to be meaningful power transfer losses. I don't discount the fact that there is a subjective difference in the feeling of riding between bikes, but I do discount that it makes an objective difference."
Brother has ordered a 61.
Updates as we get 'em :)
Hello, im new in this, hope i can bring some photos and experience when a mount my second tantan, the ttx68 new, thanks to all!
hope next week i have it
