Wanted - hardtail downcountry frame
« on: April 01, 2023, 01:15:32 PM »
Hi guys, I'm desperately looking for a hardtail frame with modern geometry similar to the Spot Rocker. Something like this:

fork: 120mm
reach: 460-485mm
stack: < 630mm
head tube angle: 66-67°

Another option would be to use a 100m frame with a geo like this and turn it into a 120mm rig:
reach: > 470mm
stack: < 610mm
head tube angle: < 68°
effective seat tube angle:  >75°
bb offset: at least 62mm

The closest ones that I've seen are (but not close enough):
- Spcycle M016
- SP-M05 (https://www.aliexpress.com/item/1005004067264835.html)
- Carbonda FM-1306

Is there even a modern carbon hardtail out there?

Hi - you are reading my mind. Just wanted to post a similar thread. :)
I'm in the same boat it seems. Looking for a downcountry hardtail with 120mm travel. Looking at your reach numbers it seems we are more or less the same height - I'm 186cm, with long legs also so I would appreciate a higher stack. Pretty much all chinese frames as I have looked have a relative low stack.

Carbonda FM1306 in 21'' looks like a good solution, but might come in too long at 480mm reach I'm afraid. Maybe combine it with a super short stem ...
How come it's not on the website of Carbonda? Is it available to order?

Looking forward to some proposal from fellow chinertowners. :)

That's the one I settled on, I tried the Haideli one, but quality didn't meet my expectations... to say the least. But it is cheap.

Most builders you will find here do not have the Amazon kind of buying experience.
You can contact Carbonda by email: wing (at) carbonda com, to discuss sizing, painting, lead time and shipping with them directly.

I purchased the SP-M05 frame a year ago and built it into a sub 20 lb rocket.   To date, I love it, but I don't have many miles on it. (under 100 miles)   For my body, I kept having to put on longer and longer stems in order to get it to balance right, climbing,  and for my long arms. (90mm stem.)
I run a 100mm travel SID SL Ultimate fork

Ok, regarding your experiences the frame is not cheap at all - if you have to buy another one  :o .

I'm actually 184cm with long legs. If you put a 120mm fork into a 100mm frame the stack height will most likely be not too low anymore ;-). If you are fine with the head angle of the FM1306 I would go for it. If you are looking for a downcountry bike the reach should be just fine for you as it still shortens a fair bit when using a 120mm fork. I would also check the effective top tube length and compare it with your current bike. I suppose you will still need a stem at 60-80mm which is already on the long side for a downcountry bike. (see attached calculation)

Well is there really no light/carbon hardtail frame out there that is designed for 120mm forks? I really wonder why the chinese manufacturers still build frames with a geo from 2018.

The Carbonda one has a 67º HA, this is not what we had in 2018  ;)

Really?! I mean that would be awesome. But the specs tell a different story. https://www.flybike-asia.com/product/260.html

With a 120mm fork, that makes less than 69º but you are definitely right !
Taking my dreams for reality...  ::)

What about going FM1306 way with 120mm and installing Slack-R???
This is then ... I doubt that Carbonda can confirm this, or at least it voids warranty most likely? It's 120mm fork (designed for 100mm) + installing Slack-R. Both points result in more stress on the head tube area as far as I understand.

1306 has 52mm upper bearing, so I guess SlackR would be only possible with some kind of spacer...

I wonder if you can buy two 52mm Slack-R inserts? One for the top and one for the bottom? You would probably have to glue the top in with epoxy.

I quote Wing regarding the 120mm fork:

FM1306 should use 100 travel fork

I quote Wing regarding the 120mm fork:

It changes the handling for sure. After a couple of rides you get used to it.

They say the same for the FM936, and most of us are riding it with a 120mm anyway 8)
Although, they seem to have given up recently for the 936 as they've built a rear triangle for 120mm.

For 936 and 909 I got an email from Katie that is designed for 100mm but 120 is okay.
I didn't ask the same for the 1306..
Regarding the head tubeangle the spcycle m016 is the only one hitting that requirement. I like the shape, but I was not so confident about the quality. That's why I took the 1306 then
I couldn't find any other hardtail frame with such a head tube angle.

Sonder bikes about 5 years ago made the Transmitter in carbon...bit was a 27.5+ bike.... I still ride the alloy version with 2.6 tyres and a 120 mm fork... Which works out as 65.5 head and 74.5 seat... Still looking for a secondhand carbon version... just a shame that it won't take 29ers...of a decent width...
