Long Teng / Mondince aero frame FM126

Pictures of the crown an the gap

Double check the height of the bearings are not different. It should be a standard MH-P16 bearing which comes in 7mm or 8mm heights. Assuming both your bearings are 8mm, you might need to buy a 7mm to reduce the gap. Otherwise, I would say that gap is probably normal for a Chinese build given manufacturing tolerances.

Its already the 7mm bearing. Frame came with 2x8mm und 1x7mm bearings.

More Pictures. The downtube is actually crazy narrow.

Looks pretty cool, how deep are those wheels  . Will be interesting to hear how it rides in the next few days.

Frame without udh hanger an without fd mount is 920g
Fork uncut 495g
Seatpost 0 setback 190g

Wheels are 78/65mm.

100% Sure. Without the crown, so only with the bearings, the headtube touches the fork.

Mine came with the crownrace and when I asked Jack he said it was needed. I used a piece of PVC to try and set the race and I don't think it will go down any farther. Mine has about a 3mm gap, larger than my 'brand name' bikes, I never paid attention to this before. I expect even serious bikers wouldnt notice anything. I think its like AMG Mercedes owners, 99% of population would know difference between C300 and C63s AMG but there is BIG difference.

Re Bearings. Jack said, 8mm is for the upper, and 7mm is for the lower, but if you need you can use the 8mm in the bottom.

Ok but did you get it seated on the bottom of the fork? In the one close up there was a gap between the fork and the crown which looked quite big.

My frame arrived yesterday.
I’m going to weigh the parts and maybe take a few pictures. At first glance, there are two drawbacks.
The fork doesn’t have an integrated cone, so you have to use one thats onto the fork crown. This makes the gap between the head tube and the fork crown relatively large, which isn’t very nice.
The biggest problem for me is that the seatpost has a minimum insertion depth of 120mm!
That means the seatpost is too short for me. Normally, a 350mm seatpost with a 100mm insertion depth is spot on for me with the SL8 geometry. So this seatpost is too short. Actually, I should probably sell the frame now. The seat height on the 54cm frame is therefore a maximum of 473mm + 220mm + 40mm = 733mm
My seat height is approx. 750mm

Damn it.

I just measured my FM126. With the seatpost inserted to the 120mm minimum, I have a crank to top of seat of ~805mm.

My seatpost is inserted to the 170 mark on the seatpost, and the crank to top of seat is 755mm.

You will be fine.

Just checked...  its not resting on the bottom of the fork, there is prob 1mm between crownrace flange and flat part of fork. Maybe I didn't hit the PVC pipe hard enough, but I thought I was giving it a decent enough wack.  I did do some googling, and it said that for the crownrace that has the little opening (can't remember what that type is called atm), that they do not have to 'go all the way down' as thats part of the design feature, whereas, the other style that doesn't have the little opening, they do need to go all the way down.

Hey, so did you ended up building your bike ?

@shayzzz and @Leon1234

Not yet, I'm waiting for some internal cable foam housing dampener - should be here this week.

Popped on the fork, handlebar, crank and rear deraulier temporarily just to get a sense and it will look excellent!

Ok so I re=googled, I was wrong, it is saying a slotted crownrace should sit flush on the fork crown.

Ok so then the gap will become smaller and it will look quite normal just like an integrated crown, that's perfect I would say:)

[bigApple]

That's how it should be. It's not possible with the fork that came with the bike and the fork crown or headset. I don't have a solution for that yet.

There are some Tricks online for example putting the fork in the freezer and heating the crown race in boiling water. Did anyone else manage to put it on completely?

More pictures and review tomorrow or on Friday.
