I'm 175, 85 inseam and bought L. But I use sqlab 16 deg bar and 35mm stem. This bar makes bike about 30mm shorter so I can use longer frame.. With normal bar I would buy M.

Thanks for your answer.

I upload 3 images, one with the current measurements on my bike, on your drawing in red with a 50mm stem, and another with the factory measurements. And carbonada measurements.

I think that size L may be fine for me.

What do you think?

Not sure about the comparison of the frame, but for the build I will do, the L was 18mm less from saddle to bar.
And the drop was 18mm more.
Quite a big difference compared to your current measurement.

And for you assuming a 760mm for the saddle height.
You would have 702mm saddle/bar.
And a 78mm drop.
All this with a stem of 40mm and 3cm of spacers.
So if you move your saddle 17mm forward and add a 18mm riser bar or more spacers you should feel at home with an L

When doing my drawings I always missed a dimension to place the saddle precisely( the height from the BB when the seatube makes an angle )
I asked Wing if I could get it, and... a day later, I got all geometry files updated with the missing dimensions.
I may look a small thing, but this level of service always amaze me.

A scoop: its real name is FM 1206 !! 

Are you stating that the Carbonda FM909 is really a Flybike  FM-1206?

Not me, Wing 

Well, seeing them side by side...

It is for sure, Carbonda always sends FM1206 drawings.

What was wrong with the axles? I always use the ones coming with the frame.
Putting some copper grease on the thread as they are hard to start with.

My only bad one is on my FM936 where I got a Torx30, that no multi tool has.
But by using/forcing an hex 6mm, I converted it 

Buddy of mine is building a 909 for his kid. Frame looks great, but the axle will not thread into the RD hanger. Axle isn't bent, so I'm thinking the frame holes don't align. The axle threads into the hanger just fine when its not in the bike frame. Anybody experience this and have a possible fix? We haven't tried grease, but curious if that was the problem the copper grease fixed.

I had this problem with another frame. Take the hanger off the frame and try to put it on the hub. My problem was that the hub didn't fit in the hanger. I had to take off some material.

I can't get the axle into the hanger with or w/o the hub. We've got two extra hangers, I may try grinding away on one of them.

Ok. You can try to put off the hanger, then put the axle in the frame, screw the axle in the hanger and put the hanger back on the frame with axle in.

Just noticed, that 909 weights were updated and now M is 1880g. It was 1770, wasn't it?

My FM909 frame in size "M" weight 1874gr.
Maybe Carbonda update the weights!?
Actual weight of my xc/marathon built is
9,40 kg including pedals and dropper post.

Awesome builds Arno!

Do you have any opinion regarding the performance of your FM909 or FM936 compared to something like an epic evo frame perhaps?

Love the bikes that you built up.

Kind regards
Christoff

Hello Christoff,
thank you for the flowers!
The FM909 and FM936 are my first XC (race) bikes.
So i have no opinion regarding the performance of both compared to an epic evo frame.
But i am absolutly "happy" with both.
My FM909 built (100/100mm) is very playfull and my FM936 built (120/106mm) is more capable in dh.
Best regards
Arno

My bike mate is a recidivist S-Works victim . He paid his Epic Evo twice as my bling FM936 that is lighter, has more travel and better components.
And I can't see any advantage with Brain on climbing compared to my always open setup.

A super light size L from a recent order, is about 2kg with some removable plastic parts
