No issue with the magnet, today I rode with 0.75L bottle and made its job. Way was a bumpy one, actually some water went oout due to vibration but it worked.

I wanted to ask you which handlebar and stem have you mounted. I am thinking in building a second one for my wife and it seems to be a good choice. Thanks

Thanks, stem is https://a.aliexpress.com/_EGffLj8, the handlebar is https://a.aliexpress.com/_EJgx8hG
One small issue with the stem is, that there is relatively small amount of spacers included.

Do you think you have space for clip on aerobars on these bars?

There is approx 1 cm on each side of the stem, so not whole lot of space  :-\

I am planning to improve a bit the headset kit from what it comes from manufacturer.
Can someone maybe help me with that?

Specs are:
Headtube:   1-1/2" Upper and Lower (Integrated); 52mm ID, 56mm OD
Bearing Size:   52mm OD, 40mm ID Upper And Lower; 7mm Height Upper, 7mm Height Lower

Does it mean I cam buy the following from Acros (for instance) and improve the assembly?
IS52 lower part 48.02.601R2S‑1.5
IS52 upper part ICR 48.02.610R1S
ICR compression ring (aluminium) 11.02.092‑AM
ICR headset cover 24.52.113-OD56-AM

Would that be compatible? All of them are for IS52 sstandard

Upgrades are always nice, but are you having any problems with your headset? My stock headset from Mondince has been working flawlessly with zero issues so far.

I do not like the cover they provided for the cable routing, also the compression ring is not the best. Bearing so far no issue, but I would like to change for the Acros one that is well sealed against dust and humidity.

Hi all,

I am planning to improve a bit the headset kit from what it comes from manufacturer.
Can someone maybe help me with that?

Specs are:
Headtube:   1-1/2" Upper and Lower (Integrated); 52mm ID, 56mm OD
Bearing Size:   52mm OD, 40mm ID Upper And Lower; 7mm Height Upper, 7mm Height Lower

I'm also planning to build a bike with this frame, but I'm a bit confused about the headset specification, too.

Does Mondince mean that "1-1/2" Upper and Lower" refers to the headset bearing size, while the fork steerer is still the standard tapered 1-1/8" to 1-1/2" (28.6 mm upper / 40 mm lower)?

My main question is about stem compatibility. I'd like to use a Syncros RR 2.0 stem (or possibly another integrated stem/cockpit). Does anyone know if the SYNCROS IS52/31.8 – IS52/42 headset is compatible with this frame? https://www.syncros.com/de/de/product/syncros-is52-31-8---is52-42-headset?article=2882490001222

Has anyone here used the Mondince integrated stem? If so, how is the quality? Are there any issues with cable routing or bearing preload?

Also, what are the key specifications I need to check when choosing a compatible stem or cockpit?
- Top cover with an outer diameter of 56 mm?
- Bearing dimensions (IS52)?
- Compression ring?
- Anything else?

Thanks in advance!

This is a partial answer at best (I don't have this frame) but many Chinese road and gravel frames more or less adhere to what I'll call the FSA ACR / Deda DCR headset standard.

FSA NO. 55R 1.5" ACR STD
https://www.fsaproshop.com/products/no-55r-1-5-acr-std?_pos=1&_sid=087a37289&_ss=r

Deda DCR Headset (this page has a nice 'spare parts' PDF for reference)
https://dedaelementi.com//headset-dcr

- tapered 1-1/2" (38.1mm) lower to 1-1/8" (28.6mm) upper fork
- upper and lower 1-1/2" angular contact bearings (ACB) for integrated headset, 51.8/51.9 × 40 × 8mm
- top cover for ø 56mm frame headtube

If I see it correctly, the Syncros components you mentioned don't follow this standard as they assume a 1-1/4" (31.8mm) upper fork steerer (a Syncros/Scott idiosyncrasy).

These are the provided head set bearings. I paired them with a Riro stem and it works fine.

++++++ REVIEW TIME  8) ++++++

USED PARTS:
- Mondince FM336 with custom Paint Job
- Ryet 3D Printed saddle
- Elitewheels SLR Gravel (god they are loud! :-D)
- TPU Tubes
- Setback Saddle by mondince
- Sunshine Cassette 12 Speed 11-46T
- Senicx T47 BB
- Senicx PR3 Gravel Crankset 170mm crankarm, 40T Chainring
- Kocevlo X01 Handlebar
- Ltwoo egr electronic groupset (Bought used)
- Shimano 160mm Discs

COSTS
Overall I paid around ~2000€ of which are only 1700€ parts for the bike (like the frame, handlebar etc.) and 235€ materials like mineral oil and tools and other stuff.
thats kind of a bargain for a bike like that. I currently weighs about 9kg which is kind of good for a gravel bike i think - what do you think?

ORDER AND DELIVERY
- Ordered on 12th May 2026 via Mail
- Delivered 19th June 2026
- They had some Issues on my order so it was delayed. When Jack told me the package is sent it took roughly 10 Days to arrive in Germany
- Package was well secured and no damage at all. I wish they had put some parts descriptions or even a manual in there as there were parts in the package which I dont know what to do with them but so far everything was right and when I built up the bike my questions about some parts answered itself.
Rating: 8/10 very well experience. Jack responded quick. Delivery was quick but with the delays in my order I cant give 10/10

UNBOXING AND BUILD
Unboxed everything and the paint job was exactly as ordered by me. Also the frame was very well manufactured: I saw no sharp ends anywhere or problems with the paintjob. As a first time builder it took me about 2-3 days to build the whole thing. I think thats fine. Only issue I ran into were the mounting brackets for the brakes. I use 160mm Discs front and rear. When I mounted the calipers with the 160 Ltwoo adapter the brakes were only slightly touching the discs. I showed it to a local bike mechanic and he also said "that looks wrong - try another adapter). I then used the 140mm adapter and thats it. So I dont know what thats about but It works now.
Rating 9/10

RIDING EXPERIENCE
Building the bike I decided to first try out road tyres and took it up a local hill. Performed pretty well. No rattling, no shaking. Just a fun bike to ride. A week later I went on a tougher Gravel route together with a friend of mine and hell yeah that was fun! Had some schwalbe tyres with only 45mm on it but the bike performed outstandingly well! Fast ascending on forest tracks, lot of stability on "single-trails" descending and a lot of speed too. I still have some Issues with my hands as I think the Ltwoo brifters are kind of small and maybe my handlebar is also a bit too short. But nothing I cant fix. New parts are already ordered and will be delivered today.
So the only 3 things I miss a little bit:
1) a slightly lighter gear for climbing (maybe trying a 48T or even 50T Cassette? Experiences?
2) a bit more top speed when descending roads (had 60 km/h max which is a bit low)
3) a bit wider brifters of the ltwoo as I think my hands are a bit too large ( any ideas how to fix it?)
Rating 10/10

Attached some pictures with road tyres and gravel tyres aswell as standard and setback seatpost.


Glad I discovered this forum. I never thougt I would be able to build up my own bike with kind of high end parts on a budget.

But the best thing: I have learnt a LOT and the next project will come soon: Road bike for my first race and triathlon ( suggestions? thought about the prebuilt seraph tt-x42 or tt-x71 or tt-r18)

Hi Spongel, verty nice build!
Go 2x and you'll have no gearing issues IMHO. Plus better chain line, less cross shifting.

I'll put my FM336 on a Balkan bikepacking tour starting end of next week. Will report back.

My build is finally done. 

Assembly went quite smooth. Brake mounts wasn't finished well and paint on the furry in this place was a bit chipped. I gave up with XG4 calipers as they barely worked on the front and didn't work at all in the rear no matter how long I bled them.

Only issue I have now that the storage cover fel off two times during a ride with a bottle and chipped the paint 🫤. I don't know what going on with it. I taped it for a now. Does anybody have same issue?

Spec:
FM 336 size L
CSC wheels 29int/34ext 45 mm deep
Panaracer Gravelking ZX 50 mm front / 45 mm rear
Shimano 105 shifters and brake calipers
Shimano GRX RX822
Shimano SLX 7100 cassette 10-51
Kocevlo bar and stem combo
Mixed saddle
Total weight 9kg

(Flat pedals are temporary. I took for a ride with my son as he was racing today)
