Carbonda FM909

So it took a while to get but we did and finally built up.  My 14yr old sons new fs race bike. 1x12 axs light bicycle wheels.

Getting closer. 11.23kg

Why Minions on an XC bike to start with, and especially if you're counting grams?

To shed half a kilo next summer

Got my frame today. Too bad its winter and snowy in Sweden.
The weight is with rear axle, ”dummy-shock” and ”protective” for seattube.

It is size M

My dust cap arrived today .
I had really good luck, the cap and spacers hang almost free, cause the envelope was pretty destroyed.

Brakes are not attached yet, everything else is finished.
11,4kg with 120mm front travel, with dropper post,  with remote for rear and front lockout, with platform pedals and bottle cages
My favorite OEM bike Canyon lux trail is listed with 11,8 in the most expensive version. Of course without pedals and cages.

Can't wait to see final build, pedalancer.
Weight is very competitive indeed.

First ride finished. Great and amazing.

  I wasn't much slower than yesterday on a gravel ride. (Carbonda 505)
I will change to sideloader cages , cut the handlebar down to 760mm and lower the front by 10mm.
Besides that I never felt so good on a mountainbike before.
(I started with mtb, realized then I like roadbikes, added a gravel and now finally came back to mtb  )

Today I realized that the rear wheel is shaking slightly.
I changed the rear wheel and also this wheel was shaking ( we do have some stock of stuff in the basement)
Then I tested a shorter axle, everything is fixed now. Unfortunately it’s to short to use it, but in principal it showed that the axle is the problem,

—> The original Carbondale axes is to long
 ( I removed the original text...here was something wrong, but the message stays  true.. axle work 181mm is 2mm to long)

—> The original Carbondale axes is to long - more in detail the part with maximum thickness starts to early, so the derailleur hanger contacts to early. This is really delicate, it’s just some tenth of mm. I tried to measure the axes with the axle completely screwed in without the wheel. It was 148,3 … this is enough to allow for tilting. A 350 DT Swiss hub as well as Ztto M1 hub showed the same issue.
Please check your rear axles! To me that looks like an issue with tolerances , if they are matching in a bad manner as  they do in my case, you may have the same issue. The axle can’t cover that.
I am thinking about how to solve that.. I am not havin this kind of tools available to remove a part of the axle

someone already had the same problem, so I did not buy an axle from carbonda. I order genuine DT Swiss with good size.

I wonder if the FM1002/1002 take the same axles as the 909; I’d assume all their 148 axles are the same.

If that’s correct, I should probably ask what model (thread length/pitch) of DT Swiss axle you bought. I’m looking for a bolt type but it would be good to know exactly what I need regardless of the brand and type.

Still waiting for my frame, as soon as it arrives I will check if the axle fits. I bought:

Forget what i wrote. It is not an edge within the axle that hits the hanger.
It's the overall length. It's roughly 2mm to long.
The hanger does not allow to screw through. It has an edge where the axle finds a stop.

If you aim for 179mm length it should be good

On the photo you see the outer side of the hanger. Do you see the tiny gap between it and the axle? That is after shortening the axle by 2mm
