Chinese Carbon MTB => 29er => Topic started by: Stef27 on October 25, 2017, 04:48:48 PM

Hello
I am interested recently in the Chinese framework, but what I could see for the moment, they are older generation executives.
very few have the boost format.
rear dimensions to 440mm .... what's that? a tank?
Since most major brands manufacture in China, why can not we find the OEM of orbea, ktm, canyon etc ...
I would dream to find the mondraker podium carbon frame, I love it.
so my question is:
which manufacturer will allow me to find a recent geo (in tune with the times)?
Chainstay length 425-430 mm
boost format
thank you
-
Unfortunately none. This question gets asked on a regular basis and still nothing from the known vendors. I'm hoping for something along the lines of the Transition Vanquish.
-
ok
so i think i have to buy a complete bike........... :-\
-
It's a pity. Modern geometry with more and more popular BOOST frame would be a bestseller...
Even my steel On-One Inbred has slacker head angle than popular chiners (analysing in AutoCAD :)).
Maybe in 2018 situation would change, but it may appear it is to late.

What is weird,is :
Big brand Frames are build in China or taiwan,so why could we not find them ?
It's ok for price,because we can find for 4-500$ a carbone frame,but it's old generation.
I calculate price to build my MTB.
With
gx sram groupsets
Xt brakesets
handlebar,stem,seatpost,frame....chinese carbone
Wheelset chinese carbone or aluminium brand(fullcrum, ZTR,mavic....)
Fork sid or other with good sold price
+ Some parts to finish
1800-2000€ for approximately 9.5kg (i think it's 19lbs)
But,with a "old frame"(new
-
It is odd. Especially since even their "new" models are coming with 440mm chainstays. The only options so far are the 27.5+ / 29 / 29+ frames like the CS-496 from Peter. With 29x2.4 tires and a 120 to 140mm fork, it should be pretty fun and similar to the Trek Stache.
I have the Workswell version as the 496 was not available at the time, and it's been great. But it still setup as a rigid bike. Maybe I should steal the 130mm Pike and carbon 29er rims from my wife's SC Tallboy 3 and see how they ride on the WW frame. I'm not sure how much she would like that though....
-
Deng Fu sells a 27.5 plus. You may check it out. Most plus bikes are boost. Not sure if theirs is.
-
I forgot a thing,important.....
I want 29".....
And i posted in the 29er forum
-
Just to know, what a modern geometry/boost bike has that is so much better ?
-
Chainstay lenght shorter = more réactive
The problem with 29" is a lumpish frame,if the chainstay length is big,the bike is slow in little corner.
Boost give a better rigidity and better chain line.
Difficult for me to explain,i haven't the good technical words.
But i prefer a 12-142 axle and RC 425mm than boost and 440mm.

The answer to the question is pretty simple.........Law. Most of the carbon frames are built in Asia by factories not owned by the bike companies. When they design a new frame and have this Asian company build it, they make them sign confidentiality agreements. They are not allowed to use any proprietary knowledge learned from building frames for others. If they do they are breaking the law and can face legal penalties not to mention loose a ton of work from others they might be building for who may no longer trust them. That's why what you see coming out of open mold designs is older technology. Those agreements on those designs have expired and the frame builder can use some of that technology on their own frames.
I have a DengFu M06 and that design incorporates some newer technologies like a 68.5 head tube angle, 73.8 seat tube angle and 435 chainstays. Yeah not 425-430 but for a full suspension frame that's pretty short. If you're looking for the latest and greatest technology from a Chiner builder you're pissing up a rope! They are not in the business of design, their forte is manufacturing.

27.5 plus is the same diameter as a 29 inch with tires mounted.. Many people run 29 inch rims and tires on their 27.5 plus bikes.

What about copy for road bike ?
They look like the true Frame,but it is not very good build...no confidence in them.
I'm ok about your FS geometry but i want a hardtrail.

I don't want 27+,it's a new fashion tyre....
I don't think,they will be here in future.
No problem for me.
Perhaps in 5 years dengfu or the others will built boost and 430mm ........with 5 years late

I think what Steve was saying is that you can get a 27.5+ frame and just put 29er wheels on it. Most are cross compatible.

Ah ok
My poor english.....sometime difficult for me.

Good question. My take on that would be road frame geometry and technology has moved at a much faster pace in years past. Not much development going on these days except for some crazy ideas that you don't see on open mold builders. The mountain bike industry has really started to come into their own therefore right now you see so much development happening. I just think the road bike industry peaked a while ago that's why you see open mold specs virtually the same as current brand name frames.
I feel for you on the hardtail desire. I have a hardtail and love it but when i built the M06 i hadn't ridden it since and it's currently up for sale. FS bikes are so good and efficient now people are getting away from hardtails except for plus size wheel size combinations.
-
Problem with FS is the Price.
Frame are more expensive.
And we have to add 1 suspension which cost too....
It's too high for my budget and i don't want a turney to save money

I looked up the DengFu 27.5er plus bike and it does have boost. So you can build it as a 29er boost and you will have the new geometry with boost. This will probably be my next bike.

Slack head angle means better handling at higher speeds and over rough terrain. Steep head angles are for racing bikes on double track or sanitized singletrack.

Oops, my bad - Slack head angle means better handling at higher speeds and over rough terrain. Steep head angles are for racing bikes on double track or sanitized singletrack.
-
there is a big chance i buy a complete bike....perhaps in several years when chineses frames will have a moderner geo.
in a near future,i'll buy stem,handlebar,seatpost in carbone and wheelsets for my new MTB(which I do not have yet :D ).
I am looking for a gravel / CX in a few months.....I am less difficult on the geo.

ICAN AC650B PLUS http://www.icanfatbike.com/carbon-27-5-plus-frameset/ seems like have perfect geometry for me, but I wonder if the tail is stiff enough... also it could be lighter.
Does anyone here tried one? see any review?
Adventages for me are: boost (I want stiffer 29x2.3 wheels), HA 68.5, CS 425mm, long WB, PF30.

The Workswell WCB-M-145 looks pretty interesting. No Boost, but it has a 68 deg HTA. The reach on a medium is decently long at 428mm for a 100mm travel bike. The reach on my medium Workswell 062 is 414mm.

Did you ask workswell about it, any availability?
They have no real pictures and nobody else is selling so it seems to be a project in development.

Hello everybody,everybody hello,
I cammanded my bike.
Merida ninety six 6000 29".
Thanks for all yours comments and help.
My next search is wheelsets crabone from china.
I'm in contact with xmiplay,they propose:
Novatec hubs 110*15/148*12, Pillar spokes, CN nipples, HR930C rims. weight is about 1450g/pair.
and price is $485/pair.
Is it good for you ?
I don't know the ximplay quality.
I'll come here time in time to read and later i'll buy a chinese carbone cx/gravel frame.
-
This one has a 435mm chainstay. May be an option.

it seems to be good.....
for me it's too late,i sent the €€€.
it will be arrive in 2 weeks

Thanks for advice but I chose different vendor. 27.5 plus is the way I'll go considering for my XC racing and progressive geometry.
My future bike (after studying many geometry charts and checking drawings in CAD) will be built on this frameset:
http://www.icanbikes.com/html/MTB/27_5ER_frame/330.html#bk_desc_tab
It will go on 29 wheels, at first on rigid fork. Low, slack, short end, long front - that's what I need.
Rised CS maybe looks funny, but in my case it is for riding not watching:)

That's just ridiculous. But, what is "steep"?

Look at these frames, seem interesting:
almost the 041 with boost
http://www.carbonbikekits.com/frames/1367-en.html (http://www.carbonbikekits.com/frames/1367-en.html)
chainstay relatively short, low seat saty and long top tube

for me it's too late,my new bike will arrive in few days.
but someone should be interested.
