Isn't it another the same as ltk266 product?
https://mondincecycle.com/product/details/id/6.html

Someone opened a topic regarding this mondincecycle site. Seems they have also Tantan fm301/LT-Rd301 mold and minimalistic frame inspired by Aethos than can be found on Alibaba or AliExpress.

Did anyone hear something more about them? Seems that website was created this year.

Chinese business model: everyone use the same factory for products, to save on R&D/manufacture cost, but compete with each other on brandings... do I get it right?

Does anyone that owns this frame can share their experience in regards to ride feels and building the bike itself?

Mine came in today. After I think it took 5 days to work out the order and 2 weeks to ship the frame, including the paint. It shipped UPS, which was fast, >1 week including customs clearance. Duties were not prepaid, but weren't too bad. Parts of the ordering process were slower or more manual than I would like, but Alisa was great, and her information so far has been accurate.

Box amusingly was one of the ones that had a rectangle on the outside to imply there was a TV inside. Packing was simple packed in foam and bubble wrap. The UDH is very skeletonized. I had asked a few others how they felt about the quality of the metal parts, and they indicated that they were typical of a Chinese factory (read: not great), but these largely seem fine.

Overall, I am pretty happy, though if I were to do it again, I might stick with a simple gloss finish rather than try a gloss and a matte, as I suspect they added the gloss on top of the matte finish, so the frame is a bit heavier than if it were gloss or matte. I will scope this later, as I have one, and I am likely to take at least a month to finish the build. Preliminary impressions are below.



Simple shapes with round tubes. Nothing fancy or aero here. Slight hourglass on the HT.



The rear caliper mounts are finished, but not well. This is not quite flat. There is enough of what looks like a flat surface that I don't anticipate any problems, but noteworthy for the picky among us,



The paint is pretty even, though the carbon does show through slightly differently in different places. I think they added a tinting agent to mask some of the rough spots. Another reason why I suspect ordering a colored tint probably would have resulted in a similar weight.



The bearing seats are darn near perfect. I dropped a couple of Cane Creek Hellbender headset bearings (52mm 36/45 ) into these, and they were a perfect fit with a Deda 36 degree C ring.





Not minty fresh, but clean enough in terms of the seat tube.


Fork seems standard fare. Its a carbon tube bonded to the fork structure. At that joint is a little less clean, but it's cleaner than an Open or 3T Fork, but messier than the Enve ones I've handled. Nothing to worry about and the carbon tube is even thickness, at least up top.




Some weights:
The frame is 789g. This includes the four bottle cage bolts + both hangers. Weighed without bolts (which I think would be the standard thing? Not sure?), it would be about 780g. This is heavier than i was hoping, but not by a lot and still within expectations. I think I goofed with the paint selection in terms of weight. I think they did the whole frame in matte and then added the gloss on top. I probably would have been just as happy selecting one or the other and saving the weight--even though this will not be a weight weenie build as it's intended to be a test mule for my 3d printed headset covers and other products.



Seatpost weights are more or less right on target too given this is a 400mm seatpost. The hardware is heavy, and the only miss I see spec-wise on this frame is here. I am not a fan of the black oxide bolt used here. That coating resists rust as long as its exposed to lubrication. Stainless is the right choice here. I will replace it with Ti anyway, given I am a light rider.





The seatpost clamp I don't love in terms of it being small and the fillet is a smaller radius than I would like, but it's there.



Other than my own choices, I have very little to complain about with this transaction. It is pretty lightweight, and just based on this initial look it seems likely to be comparable to the Elilee Blize XXE, Seka Spear, and other premium Chinese frames. Yes, it's significantly heavier than something like the Scott Addict HMX SL or even the regular HMX, but right now don't have much to complain about.

Just received the same frame in a size small, very similar paint job - I basically copied INSVNX. Inside the frame is very clean no abnormality noted but I am not an expert. All the fibers are very clean and it looks like a true monocoque frame to me. Only one spot near the bottom bracket area where ?resin was applied. I didn’t weight it yet but it’s a size small as well. Will post more pictures and feedback when bike is built. Still waiting on XM integrated handlebar and wheelset. Tire clearance appears similar to my Roadmachine 01 2020 - I wouldn’t use this frame for gravel.

Ordered different 7x9 saddle clamps from NIUJI and UDH from Wolftooth as I didn’t like those that came with the bike.

Bottom bracket area


Put on wheels just to have an idea of what it will look like and what the slopes of the top tube is really like

Your paint job looks really good! I havent verified if the Ritchey hardware works perfectly on this bike per Alisa's claims. Hopefully the Niu Ju stuff works well. I love that shop and they do seem to do a great job with machined parts.

P.S., quick tip on using Imgur embeds: if you use "h.jpg" instead of ".jpeg" in your links, the images will be resized like mine, making it easier to scroll through. You can also use "m.jpg" or "s.jpg"

This patch of resin reminds me the finish of a Winspace frame which people complained about it.

Here is a picture of a Winspace frame that shows why there is a hole in the actual mold. It seems other manufacturers use a similar technique.

So I broke out the inspection camera and took some shots of the inside of the frame.

Mostly they look like this:



Super clean walls. This is the area that leads to drive side dropout. The brake mount side is cleaner. This looks pretty nice to me.


There is a stray loose fiber by the hole for the FD cable and this one in the fork at the crown.


There is a tiny bit of stray resin where the DS chainstay meets the BB, those two loose fibers, and that's about it. I generally don't take anything away from this, but FWIW, this does suggest the frame is EPS molded and that it was made with care.

The tire clearance on this frame is good.

So far, on a spreadsheet, this frame is a winner. It's similar geo-wise to the Seka Spear RDC in their MR size.

I hope it rides well.









With a 33mm WAM tire, I can fit an 8mm hex key in between both sides of the tire and the frame. My top of tire to inside of frame measurement isn't quite right since the tires are a bit wide for my calipers; it's closer to 15mm. Regardless, a 40mm slick tire should fit with ~4mm clearance, which is probably right for a road bike. The claim that a 35mm knobby tire can fit is spot on.

The big test will come when I ride it, but so far, it seems cleanly made, is 789g w/ all hardware (or ~740g without any / ~780g with bottle cage bolts removed) in a medium despite my paint goof, has loads of tire clearance, uses UDH, and reference internal cable routing geometries. So far its living up to my expectations as the frame I was waiting for.

Have you got some time to make some rides ? The frame looks good even if it does not looks like very aero.

Love this frameset, I think I might pick one up as a project bike for the winter. Is it inspired by any existing established bikes?

No its not fully built yet. I am planning to swap some parts around including my prototype handlebar so there probably wont be pics of the build for a while or i will blur out the front end until i have the design final.

Hello, does anyone with the frame have the possibility to install gravel tires? I would be interested to know what the maximum actually is.
