Hi all,
This is my first post and I'm trying to find my way in the world of open/public mold carbon frames.
I'm interested in buying a frame and building it up with good spec. My first project will be a hardtail and if that goes well i'm definitely also getting a full sus later on.
As the topic title suggests.. for my first Chiner, I'm looking for an aggressive XC hardtail that is going to be ridden hard.
It needs to be boost and have modern geometry (i.e. longish reach, slackish headangle, steepish seatangle, short chainstay. You know the deal.. it should be able to compete with other modern bikes in this category)
I made a little comparison in key geometry numbers between some open mold models and a few big brands in the industry. See attached.
For the Chinese frames I compared the following:
LightCarbon LCM908
TanTan FM799
Trifox SDY20
Carbonda FM386
Trifox seems to have good numbers, but it's double the price compared to the others. The LightCarbon LCM908 is another contender but a slightly slacker headangle, a bit steeper seat angle and definitely a shorter chainstay would be better.
Experts of Chinertown, I kindly ask for your advice.
Is LightCarbon good quality? They gave me a price of USD 335 ex shipping which is so cheap that it worries me a bit tbh! I'm looking for a proven vendor that stands behind their products and offers good quality frames. I rather pay more if I know that the quality is good and consistent.
Is there another good contender that I'm missing in my comparison?
Thanks a lot and looking forward to the response
-
Of that lot I'd be tempted to go for the Trifox...
LightCarbon is a perfectly reputable trader but that slack seat angle and steeper h/a would put me off, particularly if you're tall and have a lot of exposed seatpost.
-
Did you check the FM916 ?
https://www.flybike-asia.com/product/175.html
Carbonda sells them in Super Light and Normal.
-
Given your list, I would also go with the Trifox. The chainstay length alone would have me looking at it. I really don't like the loss of traction during climbing that I've noticed with long chainstay frames. At least on a hardtail.

Nice one. I can't find it on the carbonda website though.
-
Given that a 34 SC has an A-C of 530mm, and the listed geometry of the LCM908 is with a 490mm A-C, it will change significantly with either a 100mm or 120mm fork. They are using the equivalent of an 80mm 29er fork for their geo; those aren’t even in production anymore.
I.e., that 69.5 degree HTA becomes a 67.5 degree HTA with a 120 up front.

Good call, I didn't realize that.

Just contact them by email.
But it is holiday time in China now, so don't expect a response before ~feb 20th
-
Bummer... Wing announced me yesterday they won't stock hardtails anymore unless for big order.
I hope it won't become a trend for single orders of other models.
They will focus on full suspension and gravel bikes.
-
Hi,
Any update on this? Trifox SDY20 looks perfect, but does not have internal port for dropper.
Looking for geo similar to new scott spark 120mm.
Thanks!
-
Just bumping this thread to see if there are any 29er Boost HT frames with geo close to 66° HA and 75° STA with a 120mm fork? I've read a bunch of posts but seems like this sort of frame is not being made in the open-mould market...
-
Another bump here. I have a spare boost 29er Wheelset and some other components that I want to throw onto a frame for racing. The Trifox looked ok but I need an XL, which they don't appear to make.
-
Did you see this thread ?
http://chinertown.com/index.php?topic=3366.0
I contacted Joy @ Haideli about it, and she said it should be in production in October.
Then asked for a 120mm fork on it, and got the usual "it is designed for 100mm".
I'm waiting for it, for two builds.
-
Did you see this thread ?
http://chinertown.com/index.php?topic=3366.0
Still pretty old-school with a 435mm reach in M, 470mm seat tube (I could only fit a 100mm dropper post) and 69° HA (120mm fork would be maybe 67.5° which is OK). Short reach and too long a seat tube are deal breakers for me.
-
Has anyone found a different source for the Trifox SDY20? The numbers and looks are identical to the Epic hardtail but they're charging a premium for gloss paint and logos that I don't want.
The new Tideace is interesting, super short chainstays at 425, but 2.35 tire limit in the rear and I'd like to run 2.4, and have to wait for production.
The new Airwolf frame is almost an Epic hardtail clone but chainstays are a little longer at 439 vs 430.
Are yall building with 100 or 120 forks? I like the idea of a lightweight xc machine but keep getting tempted by that little bit of extra travel. Need to remember that's what my 936 is for.
-
Anyone know of alternatives for the Trifox?

Anyone know of alternatives for the Trifox?
This is the closest I've found: https://www.aliexpress.com/item/4000686903353.html?spm=a2g0o.store_pc_groupList.8148356.28.68063cc60SRHWu
Geo chart is identical except for chainstay length and wheelbase being 9mm and 8mm longer. Haven't heard of the brand but there are a few other unknown sellers on Ali with it too.
-
Airwolf and Spcycle are selling this frame too:
https://www.aliexpress.com/item/1005002848032074.html?
https://www.aliexpress.com/item/1005002993932591.html?
There are also many smaller shops offering it.
My guess is that Trifox and these are the same mold, but Trifox just copied the complete geometry chart of the Epic HT, whereas the others either have a typo or just tell the truth.
-
I'm so disappointed. I put an order through to Carbonda for a FlyBike FM916 XL/21" frame, which is pretty much the only XL hardtail with somewhat modern XC geo. Money sent, custom paint agreed, good to go. A week after I've paid for my order they've sold it to someone else and have no more stock

Found something a bit more fancy from Winow:

It looks like a glued full suspension :D
Nice find !
-
LOL, it looks like a scott spark 2022, but i like the geometry
-
Yeah, looks interesting. Down Country-ish 120mm hardtail.
-
I ended up getting the Trifox. It does have 3 ports in the headtube, allowing for the internal dropper cable.
Overall, the quality is v good. I weighted the bare large frame at 912 grms.
Supplied seatpost is rubbish, a good bit less than 30.9, so loose in the frame and slipped during 1st ride. Dropper in there now.
The rear brake threads were tight, and I needed to add washers to the caliper bolt as the hole in the frame was not that deep.
The rear derailleur exit port was poor. I needed to dremel out the insert so I could feed in the outer casing.
I got the 740mm trifox flat bars, seem good quality and I weighed them at 152 grms.
Threaded BB is nice, 73mm so no spacers required.
2.35 maxxis tyres fit fine with good clearance.
The rest of the build was XT/SLX mix. Wheels are ztto microspline hubs with carbonbearm rims. 1450 grms. Snail china xtr chainring copy is nice.
-
I haven't seen this posted here yet, but is probably the best geo I've found in an XL frame so far.
68.5 HA
74 STA
471 reach (XL)
435 chainstay
https://www.workswellbikes.com/XC/wcb-m-336(29er).html
-
Follow up on the Workswell WCB-M-336 above. 519usd plus 12usd for thru axle. Another 275usd shipping to Australia! Very expensive for a hardtail tbh. Comes to the same price as the Planet X On One Whippet which is a Open Mould FlyBike FM916, but at least it will have a somewhat better level of support.
-
I did order two M29 from Haideli, 69ºHA and 425mm chainstay in size M.
With a more reasonable and usual price for a HT: $350, then with accessories, paint and shipping to Europe at about $1400 for both.

Hi guys,
does anyone know this frame?:
http://sunpeed.com/product/sunpeed-rock/
I think it is very similar to the new model that Rockrider is going to use (rockrider race 900) as well.

Any new HTs with modern geometry? I'm looking for something like BMC twostroke
-
The only thing I know of is the bxt-mtb-056. It has a 67.2 degree hta with 120mm fork and a 76-77 degree seat tube angle.
-
Yeah, but saw one cracked here on forums, also it's ugly :(
-
I have the bxt 056 and have ridden it hard over last month. Love it! The compliance out back is a little worrisome, but carbon is an amazing material. I feel post insertion is important .
Ps knobbie 2.6” without problem.

The Trifox sdy20 is 73mm bb? Site has it listed as BSA 68mm. Can you confirm?

I found Trifox frames to be a little too expensive, for nothing great in return.
Carbonda just released one hardtail again with an interesting geometry: http://chinertown.com/index.php/topic,3800.0.html
I will probably build 2 of them in the coming weeks, to test.
-
Sorry but 69 HA angle is nothing near "modern" or "progressive" geometry :(

Aaaah... these youngsters do not remember we were riding 72º HA not so long ago ;D
What would you consider to be a good angle ?
The Trifox mentionned here has 68.5º
How about putting a 120mm fork on it?
-
Aaaah... these youngsters do not remember we were riding 72º HA not so long ago ;D
Haha! No, think about it this way - I've been riding on 71 HA for "few" years and now I have tasted the progressive geometry - don't want to go back :)
-
BXT 056 after 3 months hard riding still in one piece. Love the relaxed geometry and the long front center.’

Looks great. How do you like it? Any reason you still went with Trifox instead of one of the alternatives that martocom posted? Considering one of these.

I have frame on order. Which size dropper did you get? I got the medium frame but have waiting on the bike so i can confirm insertion depth. Do you have any pictures of what you had to do to the derailleur exit port? Worried about that one.
-

I'll confirm my own: I asked a guy on youtube that built one and he measured and said it is 73mm. Sweet build video below

I am absolutely happy with SPM-05 Frame.
The geometry is very close to the Epic.
Strava recording since build:
5000 Kilometer
100000 Höhenmeter
No issue !

SP-M016 Build:
Pretty good build quality. Headset, BSA bottom bracket, derailleur hanger, axle, finish all very clean and fit well. Built up with some spare parts and RS Judy 100mm for my 13yo son to ride cross country team this year. 28 pounds with some pretty heavy wheels, tires, fork, and NX crank.
-
I almost have my Spcycle SP-M05 ready for a test ride. I purchased the frame a year ago. Finally accumulated the parts, built the wheels and put it together.
All of the parts have been sourced via Aliexpress except for: RaceFace Next Carbon cranks/BB, Scumano XT rear derailleur and shift pod, Flite saddle, PWN Coast dropper, and the tires.
I have a Rock Shock SID Ultimate SL on order to replace the Trifox carbon fork.
Hits the scale at 19.7 lbs. When I add the Rockshox front fork, weight should be under 22lbs.

Design seems BMC Twostroke “inspired” but geometries are a bit “old school” - see head angle and seat angle while bb drop is very very low - if the numbers are correct.
Interesting the headset 52/52.
In few words, a mix of old and new.

It looks a bit like that BXT hardtail frame that came out a while back due to the kink in the seat stays. If I recall, at least one person had problems with cracks at the seat stay / seat tube junction on the BXT. I would worry about there here too because it is a light frame and that sort of design puts a lot more stress at that junction. The geometry looks good though.
I don't have any experience with spcycle.

I have built bike with this frame (size M) for my girlfriend in september. I think it is the best downcountry hardtail frame at this moment - good reach numbers, good saddle position, perfect headtube angle (66.0 with 120 mm fork).
(https://i.imgur.com/Y4PasKe.jpg)
I have found only two problems:
1. Chainline must be 53 mm or wider. With smaller numbers chainring is rubbing chainstay. Checked with 32, 34 and 36-teeth chainrings on M8100 crankset (52 mm) and installed M8000-B (53.4 mm) without any problems.
2. Some calipers with 160mm rotors can not be fitted into the rear stays (M6000). But I haven't any problems with M8100 and M7100 with 180 mm.
Yesterday I have recieved the same frame for me and my friends building another two bikes with this frame. Chameleon painting is awesome.

Very nice!
Reach and stack a bit short but it is the only eastern front suspended frame with 67 head angle and 75 seat.
62mm bb drop is also fine.

Looks good, I'm strongly considering this frame. Can I ask how tall is you GF? I'm 5'7, thinking the 17" (medium) should be good. Also, what do you think of the seat stay? Is this a compliance thing? It looks less strong then a straight stay.
-
What's the weight of this frame?
Does it have ZS type headset so angleset can be installed?
