Today I have reviewed and also movement here on this axis ... I will clean and disassemble ... any solution?

Think as above...to long bolt...will check mine as soon as possible. Also had contact with Adam, said the same

Put the bolt so female is on drive side. This means the torque from the drive side doesnt cause the male to become loose. Not ideal but it works....

So ... the problem is with this axis?  is too long?  And it doesn't keep the swingarm tight enough?  The female was next to the transmission, normally I don't notice anything loosening, but still everything is tight, there is movement, it doesn't fit well.

Pull the pivot pin out of the frame and measure the length, if it's much over 80mm you'll get play.   I got that info from Adam when I had a creak (thought it was BB as well) and found a bit of play in the lower pivot.  I just filed mine down to maybe 81mm and then everything snugged up and no play.  Been solid ever since.   I did order some new lower pivot hardware, but haven't needed to touch it yet.
This is the total length ... do I have to file it?

That was what I had as well, about 83mm.  Filed mine down to almost 80mm I think and that did it for me.

Put it back together and yes the play was gone and the bolt was tightened easely! But I can feel a sharp edge at the inside of the spot where the bolt was sitting...I'm afraid it sanded through the carbon..so send Adam a question about it...would like to get a new rear because of it.

That ICAN isn't quite the same thing. Front triangle looks the same, but the rear triangle is different.

Got it! All the way from china!

But do i need to buy some seats to the bearings in the steertube?.. Or is it like i think it is, just to put the bearing against the carbon. (if you look at the pix you can se my white yt jeffsy with bearing seats) how did you guys do here?

Next question, did anyone try a deluxe ultimate 165x40? Im thinking of paring it with a sid select 120 and maybe rekon 2.4 and rekon race 2.4. Anyone running a deluxe?

Best regards

For you suspension design guys out there, how does the ICAN model compare to the Carbonda Model? I noticed that the rear triangle has a pivot point in the rear chainstay. Would that make it more of a Horst link system? I'm asking because I'm really looking for a zippy suspension platform. Right now, I ride a 2016 Diamondback Mission 2 160mm/160mm and it's a heavy tank. It's definitely the type of bike where you just sit in the saddle and spin. I'm really looking for a short travel bike that urges you to get out of the saddle and go faster, kind of like a fun hardtail. Does this frame ride like that? If not, do you guys think that the ICAN model would ride more like that?

Yes, IS (integrated) headset standard on the FM936.  Bearings just sit directly in the frame.

I can only tell you about the 936. Geo on the ICAN looks similar, but heavier with the chain stay pivot.

The 936 is a really fast fun bike, night and day from your DB. It won't be as fast through the really really rough stuff, but will fly just about everywhere else. The geo makes it really stable down hill, but you'll still be limited by the 120 mm travel. It climbs like a mountain goat, doesn't matter if it's steep and technical or a fire road.

I built it as an 11 kilo rowdy XC and have not been disappointed.

I would say small....i'm 174 and on a Medium with 35mm stem.. Medium could if you got large upper body...but standover height could be an issue then.
