Carbonda FM909

[Vipassana]

Yes exactly, I asked the question and they confirmed to me that it was drilled to pass the cables inside so that they could then go into the head tube.

Perfect. This is what I've wanted to try on my next build. AXS and internal routing.

So did we confirm if it's possible to set this frame up to be closer to 120mm rear travel like the FM936?  That would be my preference "down-country" XC bike with ultralight weight.

just had to replace the headset bearings on my madone slr (a lot earlier than usual) mostly from sweat getting into them from so much riding indoors during covid. considering that my MTB's generally go through headset bearings far more quickly than my road bikes, i'd either want the absolute most bomb proof bearings i could find or never run internal cables through the bars and headtube on my MTB. it's just a huge pain for an otherwise basic maintenance task.

i'm running etap on the madone so it was only brake housing i was having to mess with but just a ridiculously time consuming process for something that should have otherwise been a 20 minute job.

with that said, i know why you want to do it!

I suppose I didn't consider the hassle of bearing service.  Seems to me someone needs to invent a quick disconnect for brake lines that doesn't leak when disconnected.

I've been fortunate with my headset bearings. It's nice and dry here in AZ and I've got 7 years/7-8k miles on mine. They're a bit lose now, but still fine for use.


EDIT: The disconnects exist!  But that price...

I didn't think about it either 
It is generally the bottom one that fails.

There are stainless steel bearings.
Like this one: https://a.aliexpress.com/_mK9FYwJ
They last much longer.
Pour generously marine grease on top for even longer usage.

I read FM936 the whole thread and FM 936 used by many brands like NS bikes, Vitus, Steven.. etc.

Is this FM909 frame also used for any brand?

It is new. Time will tell.
But Carbonda seems good at selling their frames to brands.

@carbonazza
Would it be safe to assume the availability of the 909 frame ties in with the release of a manufacturer releasing a bike using this frame?
Do you reckon a 909 would have a harsher/firmer ride comparative to the 936?

No idea. Did you ask Carbonda already?

[johnnchc]

Yep, kinda. Carbonda won't disclose commercial information ie who is using their frames.
Haven't asked about the ride quality of 909 vs 936.

Who saw this on pinkbike.

[St0mpB0x]

Not even close. Trunion vs Standard Shock mount. Kinked top tube vs straight (although that might be size related). Swingarm shape near main pivot is quite different. Swingarm near rear axle is quite different. Headtube shape and cable ports are quite different. Shock link is quite different.

So basically they share the generic top tube mounted shock, single pivot with flex suspenion layout which has become very common in recent years but absolutely zero chance they come from the same moulds.

SC main pivot is fwd of the BB too.

[d3xophen]

Still, no one got the frame?
I am waiting for a review for this frame.

[Rickbe]

My posting the comparison photos  were only to show SC using a flex stay design like many of these other new bikes.  Not to say they were identical.  I have pre-ordered a 909 for my son to race on next season and I'm hoping it serves us well.  A team mate is racing the other model (936) and loving it.

The design is more look like Orbea Oiz. The geometry is not.
