Light Carbon makes the best frames I have built with and the enduro frame LCFS947 is a favorite of mine. The only drawback is that it cant take long dropperposts, the insert is short.
Now there seems to be a new and very interesting enduro frame on the way from Light Carbon, the LCFS948. What are your thoughts about that frame?
-
Looks like a loose copy of the suspension system used by SCOR bikes.
-
It does look similar the Scor 4060. Which was on my list when I was looking to replace my 947. Looks cool.
-
I like the modern geo and a new interesting bike. For me the VPP suspension is a wildcard. I hope it's well done and fun to ride.
To me, the suspension being overly complex is not a plus. I just want poppy progressive rear suspension.
This bike is very long, but I'd want to overfork it anyway

i like it...wondering how top tube height will work out...i recognised the frsme design from Thier ebike model LCE971

wondering if they didn't do the design or manufacturing for scor?

I don't think that is likely. Scor was founded by bike designers breaking away from another company. Also, the front triangle, rear triangle and the shock linkage are different with light carbon frames being more boxy in general.
More likely, the VPP design is free to copy and Light Carbon already has experience building bikes with suspension running through forked seat tubes.

Yes, it's the same design as LCE971, The rear triangle have some adjustment on the RC length, and the front triangle is adjusted to the shape of the MTB.
attached two photos, one is completed bike of LCE971, another is LCFS948 on designing,

Chiner frames gets cooler/better every year, bet this thing rides amazing.. Only thing that bugs me is the height of the toptube joint with the seat post, i think enduro frames should have a more aggressive look with lower standover height, but thats just looks.
-
I know people have called out the scor 4060 as a possible clone but doesn't Santa Cruz have a bike just like this too? I think the mega tower looks identical
-
You might look to book an appointment to get your glasses checked, Jeff.

That was the issue. After my visit I noticed the linkage was different. ;) That tucked shock and rear triangle had me fooled.

Is there an ETA on this frame? Spec sheet?
Been on my 947 for almost two years now and a 917 for a year and they’re fantastic. This looks like a welcome addition.

Size M will be in end of November or early December. size L takes an extra month

Sweet, would love to know pricing when its been sorted out.

The chainstay length in the chart seems to be a lie. If you zoom in on the drawing, you can see the dimension of the chainstay is 450mm (plus or minus 3mm). The drawing probably has the true chainstay length since the chart doesn't add up. The wheelbase should equal the front-center plus chainstay length (rear-center).
This is a long chainstay length while the Scor 4060 has short chainstays.
A couple posts on this thread (and maybe Light Carbon's marketing) incorrectly call the suspension "VPP". VPP has counter-rotating links, and this bike seems to have co-rotating links.

The length or RC will be 435mm.
the data is 450mm in the drawing because the drawing is for EMTB frame LCE971, the drawing of LCFS948 is no finished, so we have to use the old drawing to show it, EMTB request the longer RC.

Do you know what size the shock will be on the new LCFS948 frame?
-

In our plan the rear shock is 210*55mm,
now we are change the design to make the frame can fit for the shock with big piggy bag.

with these changes will the shock size change or just have more room?
-
We change the linkage, so there are enough room for coil shock,
and There will be external cable routing at the head tube.
-
So when do you think this frame will be avaible?

They are available to order now if you ask. I placed an order about 2 weeks ago. Was told mid Jan they would ship
-
Pls make it a stiffer rear swing arm.
If not, @lightcarbon you will get issue like that problem of
FS 381 model.
Looking forward for a size s.
-
The rear swing arm as same as which in enduro EMTB, so no need warry about it,
size S now have no plan for it, first size M and L,
-
Do tell when there is a size S. Not everyone can use 460 reach m size.
But I do understand, for L and M.

This might already be out for production, but if there is anyway to shorten the seat tube length so riders could fit a larger dropper post and have a lower stand over height, it would be really appreciated. It would also probably make the bike more attractive to a larger audience of buyers. 495mm is a very long seat tube length for a size large bike. Most manufactures try to get those below the 450mm mark.
-
Yep. STA way too high. Do try to shorten it

the size M is on testing, size L have no make the metal mold, need more time, so we have the time for seat post,
but one question is if short the length of seat tube, it's hardly make sure the enough length for inseart parts of dropper post. the seat post only can be between the two red lines,
-

after chinese new year holiday. about in late February or early March,
Now we are improving the strength of the rear triangle because some problems were discovered during testing!

Leave it as it is. like you state, you are limited on how far into the frame you can go. if you make it too short, a taller rider wond be able to get a post in far enough and will still have issues.

Thats great news. I like this frame and I´ll definitely buy it but 170 mm is a little too much travel for me. Is there any way to calculate the travel with a smaller shock, say 210x50?

The trend in the bike industry is to have a longer dropper post with a shorter seat tube. For example the ibis Ripley and Ripmo, two of the best selling bikes in the industry, have ST lengths of 418 and 432mm respectively. It allows for more customization via different length dropper post and is much nicer as you can move the seat way out of the way when you are descending. With dropper post reaching lengths of 240mm, it shouldn’t be a problem accommodating longer legged riders. Additionally, droppers are starting to have shorter and shorter insertion lengths, which can make up somewhat for a short frame insertion length. If this seller wants to sell the most amount of frames, he should try to lower the seat tube length. As it is, it will deter buyers looking for a frame with modern geometry.

well the Ibis bikes don't have a shock running through the seat tube either. have the seat post insertion lengths been posted yet? I have a 180mm dropper on LCFS947 and I have 90mm of the non-dropper post sticking out of the frame. Not once have I thought that I needed a longer dropper. I am guessing they had to go with the choices they did because of the shock placement and needing to have a specific amount of insertion length.
Also trends change, wait a few years and this may be the new "in" frame design. ;)
-
went and found the geo chart from when I ordered. looks like seat post insertion are as follows 17" (200mm) and 19" (220mm). stand over looks to be 17" (774mm) and 19" (791mm). that is about 14mm more that the LCFS947. this frame has 50mm more insertion length than the 947 as well. I would actually be able to get a longer dropper in the new frame vs my old frame for only 14mm more stand over. currently I am at the max (10mm less) insertion length to get the seat where I need it. this seems like a win to me.
-
Have anybody built a bike from this frame? i have ordered a frame but looking at the levrage ratio rising at the end it seems like air shock is the best here.
-
I received the size medium that I ordered. Frame built up just fine. Only issue was the original shock we bought was the SR Suntour Triair 2 with the sideways piggy back and the frame was about 5mm too narrow. Switched to the voro coil as the original triair is no longer available. One bummer was that all the drawings had a ISCG-05 mount shown but the frame I received did not. I asked and was told that production frames don't have it. Went with a crank based bash guard instead.
-
oh okay, i will go for the super delux coil. Do you have any pictures? i saw a geo chart with stack arund 603mm and it seems really low. and chainstays at 440mm

do you have any pictures? how do you find the stackhight?

Here is the bike. Sorry for just the one pic. I have been unable to upload pics lately.

Trying a few more pics

Nice! Have you built it with 160mm or 170mm fork? Have you been riding it? And if you have how does it feel with a coil?
My frame is on its way home.

This bike was set up as a 170/170mm, no rides yet. the trails around here are still closed. the coil will take a bit to dial in as i am unsure of the spring rate. have a few options and even a progressive spring so should be able to get something to work.
