Could also be interesting as a 'progressive' gravel frame option.  Particularly paired with a Lauf fork.   If you have pretty gravelly but very steep trails like I do.

I've learned something!

What is a progressive gravel bike?

Performance-oriented gravel bikes with longer frame proportions that are typically paired with a shorter stem, compact drop bars, or even flat bars.

Typical attributes include: Longer reach and front-center than traditional All-Road/Gravel bikes.

I think progressive is just generally used to indicate slacker head and steeper seat angles.   I didn't realize there was an 'official' definition for progressive gravel.

Though unfortunately it seems that due to some crying on German forums the optional FD mount from the early frames has been completely eliminated as an option.  Still rather have 2x on gravel.

Looks really interesting. I didn't see it on the Carbonda website, but it is shown on the Flybike site.


Any idea what the tire clearance actually is? The drawing showed 29x2.6" but the Flybike site said both 29x2.4" and 29x2.3".


Looks like it's designed for a 130 mm fork, but the 69 deg head angle is a bit steeper than I'm looking for.

I would have purchased this frame if it had a front derailleur and used it as a 2x gravel bike.
Wing advised the max chainring is 36T, so there goes a 1x gravel option too.

I'm looking at building a budget Santa Cruz Highball and this frame is the closest I've come to finding it.

Santa Cruz Highball:

Head Tube: 69.5°
Seat Tube Angle: 73°

FM-1306A

Head Tube: 69°
Seat Tube Angle: 75°

I'm new to the whole custom scene but do people think this has similar characteristics/component options to the SC Highball? Or is there a better budge carbon hardtail frame to start from? Not seen any reviews for this yet.

I get quoted for couple fs frames from major companies mentioned in the forum and go with the most reasonable one in terms of shipping cost and frame itself.
Unfortunately its a thing to consider if you are charged over 200$ for shipping.
I can also include an example for you to think out of the box.
I have no experience with the frame but, those angles are achieved with 100mm fork.(LCM909)
Can be altered 1 degree each with 120mm fork 69-73.

For many years the cheapest shipping for a frame was around $90 by EMS, the postal service. So we talk about a $100 difference.
I advise people to go with XDB, WXY like shipping companies (to Europe) for customs "optimisations", speed, costs and hassle.
And it was and still is $150-180 for years.
y
Amazon discovered very early that shipping costs were a psychological barrier to buy and optimised about it.
For the budget of a bike and the years you will ride it, it can be relativised.

Thank you very much for sharing info about 1306A.
I ordered one size XL and it’s already shipped. I hope I will get it in January.
I wonder why there is no information about it on Carbonda web site?
Can you please share your experience with this frame?

May I ask for a photo of the finished build? :)  and how is your impression of the bike? I am thinking of the 1306 although I would like a smaller steering angle around 67°, which I can't really find for hardtail frames with 100.

Sure. If everything goes according to plans, the first one will be built this weekend.

Finally built the two this weekend !
No problem to report about the frame.
Brake mounts were aligned. Smooth inside. Headtube ends clean.
Same great build quality as usual from Carbonda.

The pink one is for my sister !
Unfortunately I did order a 31.6 seat tube.::) Waiting for the 30.9 to arrive.

With GX AXS, a ZTTO cassette as she wanted a rainbow, but didn't want to invest in an eagle cassette, we'll see how it goes.
In the picture it is a ZTTO chain, but I don't like the noise it makes, so I have an XX1 on order to replace it.
The wheels are the XC925 from lightbicycle.com with 240 EXP hubs, CX-Rays spokes.

The ZRACE Hardrock crankset looks well built.
The Onirii M4 brakes were a very nice surprise, they look awesome and were very easy to assemble, no bleed required.

The brake adapters coming with the frame F PM160->180 and R FM->PM are a bit chunky, but free  ;)
I had to file a mm or so from the rear one to let the M4 totally on it.

The fork is temporary, she's not a rock garden type of rider, and I try to convince her a rigid fork will be enough.
If it works, we'll order a pink one, if not, we'll buy another fork.

Post by: carbonazza on February 20, 2023, 03:11:15 AM
The second black one(size L, the pink is in M) is more on a budget build.
Shimano M6100 components.
DT-Swiss 1900 wheels.
Onirii M4 brakes(I had to bleed the rear, just putting the funnel, and getting some bubble out of the lever).
A Judy fork.
A Elita one seatpost and a UNO stem too.

Nice! I’ve been thinking about one of these for a flat bar build that would be mainly for road and gravel with only occasional light (but rooty and eroded) trail. Probably thinking rigid fork and gravel rims/tires. But would love to see more of what others are doing with these!

Really nice, thank you for sharing!
Your sister has a cool brother  8).
For my case... it's for my father. The goal is to be lightweight fun bike for nothing more than riding on the broad forest "highways" .

I am still on struggling with the color scheme,  was on blue with white, but then i got told that's the color of the "wrong" soccer club  ::). So maybe I will just do a matte purple-green with fading to black. And decals I will do on my own maybe glossy dark grey  or also black.

I want to finalize the colors tomorrow... then let's see.
Btw: I bought a brake set with PM front brake und FM rear, so I won't need any converting adapters.

Post by: Pedaldancer on February 21, 2023, 11:38:59 AM
From Onirii ?

No. Just quite boring Shimano XT. Some online shops offer this mixed kit.
I am not very brave to use a Chinese brake for my dad. Before that I must at least have tested it by myself.
Do you already have experience with Onirii?

They sell FM calipers, 2-piston, so I was wondering if you did make a mullet assembly.

 :-X no no no no. Don't get it like this. It's just in case of maintenance I won't be able to just do it immediately. It's a 450km distance between us. That's why I only picked components where I know they won't need to much care.
It's not because I think the Chinese brakes are dangerous. In fact I am very curious about using them but in case something must be checked immediately I thought a XT is a good choice, cause a local bikeshop can handle them.

@Pedaldancer, it was a joke, no worries  ;D

Just to report, that the ZTTO chain noise was coming from a bad rear derailleur setup  ::)
The final weight is 8.3Kg. I received the seatpost yesterday, Aliexpress has a very fast delivery to Belgium since a few months.

That's really not heavy  8). Have to admit i think my gravel comes up to the same value.. the road handle bar is really heavy compared to a lightweight flatbar. And the frame of the 1306 is much lighter than the 505 :o.
I am pretty excited how it will be for a build with a 100mm rockshox SID SL. Also here i didn't take the ultimate, as the lockout cartridge is sometimes leaking (guess what happened with mine).
I am finalizing the color sketch tonight hopefully  ;D.  Hope Wing can help me..i can choose RAL but I want the best fitting YS metallic/pearlized colors instead ::). I am fine for slight deviations as long as dark blue remains dark blue and doesn't get red or something like that ;D

2 carbonazza

Do you think 38T chainring would fit?

It’s fairly likely that at least 2-4 extra teeth could be fit if a symmetric direct mount crank such as Raceface Cinch was used and the ring was flipped. This is usually only done with fat bikes (for tire clearance on 4.6-4.8”) and obviously moves the chain line outboard 8mm but it should allow a substantially bigger ring and chain line crunchiness would probably only significantly affect the granny.

Nice builds! Be careful with Hardrock Cranks: inner bolt is aluminum so it is easy to break it if you are overtightening cranks.
I already got frame and planning to build the bike soon.
Also got mine with flat mount adapter… but I thought it is FM 160 => PM 160. Are you sure it is FM to PM 180?

Yes, it is FM160-PM160 on the rear.
And the rigid fork has a PM 160 to PM 180mm adapter

Hello everybody,

 ;D I still must wait a little bit, but the frame is painted.
 8) it turned out really great. Exactly as the drawing.
Let's see when it is here.. since it's for my Dad, I definitely "must" and will do some test rides to have all screwed connections and bearings settled so he won't need to do anything, just hop on and ride.

The wheels are already finished,I built a robust combination of Duke Aluminum rims , CX Ray and DT Swiss 350 hubs.. and to give it a tiny bit of shine i took blue nipples.  8) can't upload a photo of them ... don't know why.

This should be a bright teal regarding colour composition. So it would not match the SID blue. I have seen some mountainbikes with bright area on the steering and a dark fork. It looks really nice.

Actually, this build started from fork. I bought it on local market for a good price in the beginning of winter. And on the last stage I noticed orange grips in local shop and thought:  “Hm… why not?” Now it feels good. Orange feels sunny and not so gloomily like all black)

Hi all

First post here. Have been following for a little while to get advice and inspiration for a new build, which I finished yesterday. So thought I’d contribute with info and experience in case useful/interesting for others.

Build list:

- FM1306a XL in RAL 1015 (light ivory)
- XMCarbonspeed wheelbuild KAS930C 29er T800 on DT Swiss 350 with Sapim
- Fox step cast 32
- Formula cura brakes
- SLX cranks, rear mech, XT chain, BB
- ZRACE chainring
- Sunshine cassette 10-50
- BikeYoke Divine SL dropper
- Selcof bars
- ZTTO XC stem
- Barzo tyres
- Cheap, light Ali saddle
- Risk grips and seat clamp
- Ritchey headset
- XT pedals

Weight 9.68Kg including cage and Garmin mount.

Dealing with Wing at Carbonda was great - really helpful and quick communication. The frame and paint quality seems first-rate, can’t find any faults at all. Likewise Peter at XMCarbonspeed. And the wheels arrived with me in the UK about 10 days after I paid for them - super fast!

Most of the Ali stuff looks decent, albeit yet to ride. The Sunshine cassette seemed harder to index than it should have been. The bar plugs that came with the Risk grips broke when fitting them. Otherwise all looks good.

I replaced the top section of the headset that Carbonda supplied with a Ritchey 1,1/2 to 1,1/8, based on feedback on another thread.

I’ll chop off the rest of the steerer once I’ve dialled the position - I think the -20 degree ZTTO stem might be a bit too aggressive….

Photos hopefully attached!

Thanks. The gold bits are vinyl decals - good spot! I wasn’t 100% sure what to go with and so thought I’d experiment a bit. Actually a pretty close match to the kashima gold on the forks.

Good luck with your build, will be interested to see how it goes

The build is finished.
Easy riding fun bike.. no competition and no competitive riding. The exact height will be adjusted as soon I can handle the bike over. I expect that I can take out most of the spacers. 

Unfortunately the SID has malfunction in the lockout... I must go into communication with the shop. Guess it's just a matter of time to get that fixed.

Today I took the grips and put them to my 909  ::)
I must order them again..  had some pain in the wrist, which is gone with this grips

Sorry for the extreeeemely long delay.
The unread posts on the forum, looses some after a while.

You might've heard from Wing by now.
It is boost – both front and rear.

I had the black fork in the workshop, it was a test, the rider wanted a suspension.
But I suggested a rigid would be fine for the type of riding she does.
After a few weeks, we ordered a pink one !

As Wing warned me, it is slightly different, as it was not painted together with the frame.
It's kinda hard to spot unless you're looking for it.
And nope, it's not too pink  ;)
Actually, everyone she bumps into wants to chat about her bike.
