Re: Carbonda FM909 This should visualize the different progression characteristics of the FM936 and FM909.

The blue line is the overall force needed to go from 0 to full travel.
The red line is the force needed to get the next 1mm of travel at any given point.

Both shocks are the same except for a slightly bigger volume spacer in the FM936 to match the overall bottom out resistances.

As you can see, the FM909 has a more pronounced "dip" in the late mid stroke whereas the FM936 is more evenly progressive. So with the same SAG and bottom out force, the FM936 will offer a better mid stroke platform and sit higher in its travel. Maybe the soft mid stroke of the FM909 has its advantages for an XC bike, but for down country, the FM936 should be better suited - also because of the 10-15mm extra travel.

Re: Carbonda FM909 Greetings to all.
I received my frame, which I ordered in October last year.
Frame sailed from China to Ukraine for exactly 2 months by sea.
The frame looks much better than my old FM936. It is also lighter by 300g, the weight of the bare frame reaches 1960g.
The quality of the seats is high. Bearings 6901*2 and 6801*8 are installed in the frame. The frame is assembled on 12 axes, FM936 was on 10 axes.
There is no protection of the bearings from dirt. The construction is such that there is nowhere to insert even custom seals.
The headset consists of two healthy 52mm bearings. Why this was done is not clear, it is heavy.
Really liked the SRAM UDH rear derailleur holder. although for its quick replacement you need an ALLEN KEY 10mm.
I will build a bike soon, it's a pity that there is no place to ride now (

Just a heads up for those interested.  In my conversations with Wing, trying to decide between the FM1001 and FM909, for a DC type bike, he mentioned that the FM936 may be offered to end users with official provision of 115-120mm rear travel - (N.B. they already do this for brands).

I was really hoping for a 909DC rather than 936DC, as the dirt is so fine and so much of it here, that it's like riding powdery snow on some trails.  I've decided high horizontal rear shock mount is definitely the way to go.
That sounds very interesting, rear travel was more or less the only reason I didn't go for the 936 in the first place. If you put a 130mm fork on the bike together with a dedicated 120mm rear end its geometry is almost Rocky Mountain Element like and that would be a big reason to reconsider ...
