And keeping in mind: OEM SL8 is around 700g, the X68 araing 840g, means 20% more material to cover up non-optimal layup pattern ... saving 4k on a frame

That's the same pretty much as the Pro Model. i think your looking at 850-900g for a 54cm
My genuine SL8 54CM IS 700g
That's acceptable and well light compared wit some of the OEM open mould generally around 1000g

On price, i heard that the factory that makes frames for Factor charges Factor less than $500 per frame...

Price ≠ Quality – Hard Facts on Building Blocks, Smartphones, Carbon Bikes & Cars
Many people assume: High price = high quality, low price = cheap junk. But that’s not necessarily true. Quality means meeting requirements – and these are set individually by each customer. Additionally, there are standards like ISO norms.

A clear example: Building Blocks. LEGO, the European Danish brand, charges high prices. But if you compare their products to Chinese competitors like Pantasy or Panlos or  Funwhole , you might be shocked.

Facts:
✔️ Chinese brands offer products at half the price – with better quality!
✔️ No scratches on the bricks
✔️ Less color variation
✔️ Printed parts instead of cheap stickers
✔️ Higher-quality prints (LEGO prints only once, causing colors to shine through)

LEGO cuts costs everywhere – and it shows. Price is not a guarantee for quality or "good" Product.

The same applies to smartphones.
What do you think an iPhone costs to produce? Just a few hundred euros – but it sells for five times that amount! Here, you’re not paying for quality but for branding, marketing, and profit margins.

And it’s no different with carbon bikes.
According to my research, a carbon frame costs around €300–600 to manufacture. Important: This refers to production costs, not the retail price or sales price! Yet, these bikes are sold for thousands in stores.

Even cars follow this pattern.
Take the Xiaomi SU7 Max: In China, it costs around €38,000, but in Germany, the price jumps to €70,000! This massive markup isn’t about quality – it’s about import taxes, branding, and extra costs.

I will be keen on hearing more ride impressions from the folks in here. Seems like specifically the X68 should be very close to the actual SL8. Only time will tell...

As far as I can tell from this thread, only you and Sander have genuine sl8's-the ride impressions from the rest of us are likely meaningless.

FWIW, I'm only 165 cm and 60 kg with an old guy's ftp to match, so my ride impressions will be skewed. Unless the bike is a complete noodle or rides like a 2x4 I'll likely think its ok. My other bikes are high end mixed materials or ti and can't really serve as data points. Closest thing to an actual sl series that I've owned was an older SS Evo.

Well, after the first 100km on the bike I can confirm that it is very rigid. Having used a Velobuild 268 about 5000km last year. This Tantan X68 shows from the outset the differences in driving.
I won't go into details of whether it's easier to maintain high speed at less watts, but I've been able to see that in strong sprints at 900 watts 268 It was more flexible than this bike

I can compare it at least to my SL7 on which I have 120.000 km :D

Btw so can someone confirm me that it is compatible with front 140 mm disc rotors?

Yeah so a local racer here just contacted me telling he ordered an X68 in the same size I ride, size 56.

He said once the frame is in his hands and built, he's happy to let me demo it. The lord giveth...

This is his order:

Sweet color, don't drop it.

Haha I stopped drinking 16 months ago. Ironically the last drink I had was tequila I think. It sucks tbh. No spirit-free cocktail can replace the taste of a good old fashion...

Will be very curious to hear your thoughts on how the 2 frames compare, given you're pushing equipment in ways that 90+% of the users on this forum dont.

Yes I ride a lot with yearsly also 400.000m elevation and rac(ed) a lot with a usually around 20h of training per week. Thus I know my Tarmac SL7 very very well. I was also a bit sceptical about the chinese frames. But recently I bought a Carbonda 505 SL as gravel/road bike and i am amazed of how well it rides also compared to my SL7. Thus for only 700 dollars I will give the Seraph a try. I will even stick the same components on it, same wheels, same groupset (found a ultegra 11 speed di2 for cheap from a local Conti riders old second bike), same saddle and most importantly i have also on my SL7 the Roval Rapide cockpit, so I can compare that. I will try to report here.

Still wondering if the 140mm front brake disc will work though.

Via e-Mail they confirmed to me, that the frame works with 140/140, and that another adapter is needed for 160. I ordered just 2 weeks ago, so it'll take some time till I can confirm first hand.

AFAIK default rotor size for SL8 is 160mm for the front fork, so you may need to buy a cheap reverse disc rotor size adapter from 160mm to a 140mm reducer.
Would look forward to your build and experience bro, good luck!

PS Saw this video over at youtube, I can see the guy simply fipped the disc rotor mount;

My good man, please make a dedicated thread here to share your thoughts when you're done. You could break the internet. Genuinely, if you transfer the components, including wheels, tyres, cockpit, given how much you ride, your FTP, the type of riding you do, you comparing a real SL7 to this frame will credibly answer questions almost every one looking at chinese frames is asking. I would even want you on the nero show podcast shooting $hit w Jesse Coyle, because again, you'd be credible.

It's exciting :D

Haha i can think of that when I have the frame. Either a thread or a good post here. I for sure will abuse the frame, while Im not pushing insane watts (threshold around 335w with 65kg) I am for sure relative competitive.

But yes I cannot wait to have the frame in my hands. Being on the nero show would be maybe a bit to much.

Have the frame built with Ultegra di2 11s and Onirii pedals, some 45mm deep heavy wheels and S-Works Power, weighs in at 7.2kg.

I'm having an issue with brake caliper mounts on the front, they aren't faced and my LBS says they can't face them because of the unusual length between the both screws.. I think with the Park Tool facing tool this should be fixable, just have to find a bike shop that will do this for me.

I'm excited about the first kilometers on the bike in the next weeks. Can only compare to my SL6 clone from Delihea/Trifox

Yep definitely interested in reading some more reviews and maybe some photos.
Was thinking of Taiwan Eisen Frame but again maybe X68. Tan Tab said the manufacture it but who knows.
If we could get some cold hard evidence they did and were not trading frames I might pull the trigger. But will read as I am i no rush to get another frame as I would use as a winter bike in UK anyway
