Long Teng / Mondince aero frame FM126

[Serge_K]

Guys, I am seriously considering that frame. I do 80% road and 20% compacted gravel road. Do you think that bike on 32C can handle that? Thinking of pairing with 50-55mm wheels with titaniiun spoked to get some compliance?

20pc gravel is a lot of gravel. You'd be almost certainly better served by the light carbon 18D.

That’s what I think but I like the go fast look of mondince! The gravel part is really nicely compared, I currently run on 40C on it and maintain an easy 28-30km/h

you do you
I would not ride any type of gravel on 32C when you can get 35C that rolls just as fast, and a frame that can clear 38C and still go fast.
Canning isnt shoulding.
That said, you CAN ride light gravel on 32C tyres. It sucks, but you can. You can also still ride 25C on the road

I am 100% in agreement with you, but I like the idea of an aero looking bike and ideally I wanted that 35c clearance

PSA (kinda). You can also buy this frame on Longteng. Just e-mail Alisa and tell her you want to buy RD302

​💬 Communication & Customer Service

​An absolute flawless experience with Mondince. Perfect communication via WhatsApp: super available, highly responsive, and answers every single question. A real pleasure!

​📦 Lead Times & Shipping
​Production: Since this is a brand-new frame, there was no stock yet (which I knew beforehand). There was a slight delay with the paint job, but completely normal for this level of finish.

​Shipping: Shipped via DPD, took 1 month to arrive in France. Just to be clear, the delay was caused by DPD once the package reached Europe—Mondince is not to blame here! The package arrived in great condition, and all components were extremely well packed.

​🎨 Frame Finish & Carbon Inspection
​Aesthetics: The glossy white paint is absolutely perfect. The bottom bracket and brake caliper mounts are well-faced (just a minor residue of clear resin on the BB, easily cleaned).

​Inside the frame: Of course, I checked it with an endoscopic camera! The carbon lay-up is super clean and smooth. There are just a few minor "carbon flakes" around the bottle cage inserts, but they should be completely inconsequential.

​🔧 Build Details
​Everything went perfectly smooth thanks to the excellent quality of the parts. However, here are 3 quick points to watch out for if you're building one:
1️⃣ Di2 Battery Mount: The one provided wasn't the right size. Fortunately, the seatpost is narrow enough that the battery fits snugly inside without a mount for the short term. Please note that the seatpost is 350 mm length for the size 54. Mondince is already sending over a replacement mount.
2️⃣ Crown Race: First crown race did not fit correctly. Since now, the problem is solved. Mondince has developped a new one. All new orders will have the new one.
3️⃣ Bearings: Take note of the sizes—the upper bearing is 8 cm in height, and the lower bearing is 7 cm.

​⚖️ Scale Verification
​For this SL version in size 54 (with the white paint, which is the heaviest finish option):
​Frame only (including thru-axles, derailleur hanger, screws...): 1172 g
​Fork (uncut): 549 g

​(I have not checked the tire clearance).

​🔥 Initial Verdict
​Based purely on the build and mechanical quality: I highly recommend Mondince.
 Honestly, if you want an excellent quality aero bike at a competitive price, go for it.

What torque setting did you use for the seatpost clamp?

How is the ride feel and did anyone order the ultralight instead of the superlight?

[BeR]

What torque setting did you use for the seatpost clamp?

Max 6 N.m. I set 5 N.m with carbon paste, no slipping.

I did, size 54 - but they failed and missed that my frame was supposed to be Metallic paint, so im waiting for re-painting. Told them they need to remove old paint, otherwise there was no use to order ultralight 😊
Hopefully finished during this week or next.

I ordered the ultralight, had it painted two colors glossy. Wasn't going for a minimal weight, just figured I'd order the lightest frame offered and not worry about it beyond that. Frame weight in size 58cm with front and rear derailleur hangers, but no thru axles, is 1054g. Happy so far and it looks good; consistent on the carbon layup looking clean minus the bottle cage bolts which doesn't bother me. Want to get a shop to cut the fork down before I do the rest of the build and was too busy bikepacking last weekend to sort this out. Honestly, I'm partially killing time until I get the new crown race sent to me.

While I got the ultralight, that's kind of where the ultralight ends. Did a budget approach for the groupset. Super excited to get it together in the next week or two.

Did anyone build up the bike in the carbon black and has some photos?
