Seen it last week and it looks like the cervelo/focus one, but it's not even cheaper. Got one at the LBS for 25CHF, seen it even cheaper on bike24

What are the 150/102/135mm sizes?

For people who want to spin at 400 RPMs! 

Yeah, I think the seller should clarify that part.

Not familiar with the name Delihea.

I note the shop listed on AliX on Oct23 only. Their business licence says ... ELECTRONIC commerce, established Mar21. So...
There are a few YT videos of people reviewing Delihea bikes, from much before 2023. From people buying on AliX.
Can't find a website for Delihea.

the ck-two that takes 32C looks VERY interesting. But that frame ticks all the boxes for 2024, i'd say.

I dont think i've seen this frame before. The other one with 28C looks much less future proof and relevant in 2024.

Yeah now that I look at it, the CK-One might be an older model. The Delihea brand has been around for awhile. I think they have small presence in Asia. They used to sell from their website, but I believe they have shifted mainly to AliExpress for selling their framesets. Most of the frames appear to be just rebadged TFSA frames, but I can't seem to locate who makes the CK-Two.

Threaded BB68 or T47 both appeal to me in terms of maintenance and 32c tire clearance makes a huge difference in flexibility from light gravel to dedicated road bike. The only other frame that ticks the same boxes for me is the ICAN FL1 which comes in at sub-800g, 32c tire clearance and T47 threaded bottom bracket. I'd be curious to see how much cheaper the CK-Two would be during an AliEx coupon discount sale. I only wish it was a sub 900g frame.

There's also a TX-R7101-SGS derailleur mentioned there - TX is for road, but SGS is long cage. It might be that this is a wide-range 2x option.

If it's a 2x gravel electronic groupset, I'm sold. I hate 1x. I prefer riding to the trails which requires doing road miles beforehand. I find driving to a trail just to ride a bike to be incredibly lame. Probably accounts for why most of MTB'ers I see in my area are switching to e-bikes to make up for their lack of fitness!

Just a heads up with the ER9. I found if shifting maybe 3-4 gears without pedaling, you can derail the chain and jam it on the RD cage. I also ended up scruffing up the inner cage plate. I'm way too OCD, so I removed it, sanded it down and repainted the cage matte black with some paint primer.

It does make me wish there were some optional cage replacements in case of major damage.

On the plus side of LTwoo's missteps, it's allowed more Chinese groupset competition to catch up. Wheeltop and soon Magene will also be in the electronic groupset market. I haven't heard anything from Sensah, but if they do make an electronic groupset there will be four potential players. Whoever can step up quality and customer service will own the Chinese cycling market which is on the rise.

I think within the next 3-5 years one of these companies will come out on top. Also that's the number that was thrown around for a Chinese sponsored cycling team to enter the World Tour. That means one of these manufacturers will really need to step up reliability if they want to represent.

Very pretty build (with the exception of that saddle bag !
What frame is that?

It's a TFSA disc frameset (SL6 clone). I believe TFSA is the OEM for the Delihea framesets as well. I initially bought it because it was cheap, but surprisingly it's held up to quite a bit of abuse.

Though if I were to build a new bike I'd probably go with one the Aethos clones floating around. There's just too much climbing in my area!

I had the GR9 hydraulic levers paired with the Zrace XG calipers, design, weight and color choice were attractive at the time.
My experience with the calipers was less than stelar... the back brake did never work, even after several bleeds. The brake feeling was always soft and not very assuring on steep downhill rides. Installed the heavier L-Twoo calipers and breaking feel and performance is now good.

This is funny, I just did the opposite. My LTwoo calipers worked fine, but the weight gain going with the ER9 was bugging me. I had ZRace XG calipers I bought on a whim awhile back and decided to install them. In the process I also opted to switch to 140mm rear rotors and cut a few extra grams. I didn't even do a proper bleed since I did a direct swap with the calipers. Brake feel is surprisingly good with the ER9 levers. The weight savings is quite significant because I cut about 100g from the calipers.

BTW - do you have a photo of your heat shrink cables? I'm using a coat of rubber cement + dielectric grease on my cables, but now I'm realizing it's a bit of a dirt magnet. I'd prefer a much cleaner application if possible!

Do update us on how it goes with those calipers, please.

After I posted this, I ended up switching both my road bikes to a 160/140 Kactus rotor setup with these ZRace XG calipers. I had no problem with the Ltwoo calipers, but they're just heavy. The Kactus rotors have excellent bite (using them on my gravel bike), so I'm presume going to 140mm in the rear shouldn't be an issue for road. I'll be able to see how the ZRace XG/Kactus combo handles on my local mountain descents.
