Got some information from Wendy at LC on the new XC frtame. Not availbale to end users at present.
-
Any idea when it will be available to us? This looks promising.
-
No, she said "not available to end users yet and I have no idea about that'. Think they are waiting for bike companies to take up the design first.
-
Earlier this summer another user was told there was a minimum order quantity of 20 for this frame. Through round about ways I got information that there was at least one entity that ordered multiple frames but I can't be sure. I've kept my eyes peeled but haven't seen anything close come to market. Although being in the USA I am not as aware of the little European or Asian brands so it could be out there.
It's a shame everyone can't access this frame. It seems like it's what the lcfs911 was intended to be. Unfortunately due to lack of frame clearance at full compression with 165x45 shock the 911 didn't turn out that way. I had the 911 real quick because of a mix up and I think you could maybe squeeze a 42.5 stroke shock. I would have thought they would have given this 917 a little longer reach and steepened the seat tube based on current trends. . It's like they took the front half of the 911 front triangle geometry and messed with the seat tube and rear triangle to make this one.

Hello guys, I'm new on this forum but I read it for a pretty long time now because I build and ride Chinese frames since 6 years now.
The last one was a Hongfu FM258 that I loved, but unfortunatelly it was stolen on my car. I found a KTM Scarp Sonic to replace it for this (strange) season, but it doesn't give me the same pleasure as the Hongfu, and my addiction for full black frames has resurfaced ;D
So I was looking for a new one, with a much modern geometry than the Hongfu, and the LCFS917 caught my eye despite the little information we can find about him.
So I tried my luck without conviction, by sending an email to LightCarbon, and I was pleasantly surprised when they replied that I could indeed buy this frame !
For the moment I have paid the deposite, and the frame should be ready end of October. I will give you update at this moment and make a little review of it of course.
(Sorry for my English, I am a French guy and I know that we are not known for our level in foreign languages ;) )
-
... the frame should be ready end of October...
(Sorry for my English, I am a French guy and I know that we are not known for our level in foreign languages ;) )
I look forward for your build ! What BB type were available ?
No worries for your English, most seem to understand us ;D
-
I have asked for a BSA but it is only available in pressfit BB92. Not really a problem for me, I find the Sram Dub BB92 not so bad and pretty cheap.
-
I would recommend ordering a couple extra derailleur hangers and spares of all the suspension bolts. The parts aren't too expensive but the shipping will add up and you'll eliminate any downtime
-
I just noticed that LightCarbon has some lcfs917 teasers on their home page. They have a rendering of the above Development & Design part way down on the left. And the bike behind the "About us" and "Contact Us" is a fully built and ridden LCFS917. It's interesting that they have it built up with what looks like a DVO Sapphire and piggy back DVO topaz shock. Never would have guessed it would fit a piggyback.

Ok, ok, now that we know it is very nice and nicely equipped.
How much does it weight ? ;)
Do you have other sides pictures ?
I'm going to go blue as well.
-
not mine, this picture is from LC's site, as mentioned by the previous poster
-
I followed a link in the LCFS947 thread and ended up at some site in the Netherlands. LCFS917 looks to be available there. Jmcarbonframe.nl

A little update of my order for this frame, it is finally ready to ship ! I bought an extra derailleur hanger but I don't take a spare kit of bolts because it is $100 and I never had to replace a bolt on a frame.
Here is a picture they sent to me, it looks pretty good with the UD glossy finish I have asked.

Is it BB92 or bigger ?
-
It is BB92.
For the moment, I should receive the rims today and except the frame and spokes, I have all components with me.
I can't wait to start the build ! ;D

Robin, how tall are you and did you go with medium (18) or large (20)?
What was the price if you don't mind me asking.
Thanks
Tim

Hi Tim,
I am 1m82 tall and took the size L (20 "). I'll put a short stem in 70mm and I would refind the position I had on my last bike (Hongfu FM258 in 19").
The frame cost me a total of 833 € with an additional derailleur hanger, and delivery by XDB with pre-paid taxes.
-
Maybe a daft question but does anyone know what shock this could be run with for a 100/100 setup? and would the bike 'work'?... obviously not in the literal sense, just more in the sense of lowering a range rover won't make it a go kart...
Ideally looking for a full sus marathon bike, 100/100 - trunion and boost... usual suspects such as hong-fu 258 and carbonda 936 considered, but who doesn't like something new!!!.
-
I planned to mount the bike in a 100/100 setup with a 165x40 shock. The head tube angle will be a little more open so a little less stable going downhill, but the seat tube angle will be a little more straightened and therefore more efficient on the climb, which I am looking for (I do XCO competition) .
-
The hongfu FM258 was really cool, but without trunnion mount and geometry is less modern as two others.
I find the Carbonda a little to extreme, so this LightCarbon is a really good compromise for me.
I stumbled across the photo of this bike which I really liked (I'm not talking about paintjob...), and after a lot of research I discovered that it was about this frame. It is therefore mounted in 100/100 and that does not seem to degrade the geometry.

The photo looks like a standard rather than trunnion-mount shock.
Guessing the 40mm rather than 45mm should give the 100mm then. sounds a decent option then. Thanks

Even set up 120/120 the bottom bracket is pretty low and I get pedal strikes. I would think going 100/100 would make it worse. If you go 100/100 I would recommend going with a 165mm or 170mm crank. If you want low travel maybe run 100mm rear and 120mm up front to keep the bottom bracket higher
-
You're talking about the Hongfu I guess ? Indeed BB height was low but similar to Scott Spark.
For the LCFS917, I just add its geometry in "geometrygeeks.bike" and compared to Trail bikes in 120mm (Oiz TR, Epic Evo, Spark 120) its BB is higher than these ones, that are also mounted in 100/100 setup, so not a problem in my opinion for LCFS917.

Remind me to answer once you have your frame in hand

The frame has finally arrived at home! I weighed all the parts and the frame is rather light, I expected heavier in size 20" in non-SL version: 1858g without the small parts and 1898g with the hardware and the derailleur hanger.
In terms of finishes it is really high-end, the glossy black paint is magnificent, the inside of the frame is perfectly smooth, the ducts are well made, the wheel axle is light (39g) and well finished, ... You will understand that I am very satisfied for the moment! ;D
I made a small decoration with rather sober brushed gold stickers, and I made a protection of the chainstay with 3m 2228 tape, it does not look bad at all and I will try to take some pictures tomorrow.
To sum up, the frame took a little less than 2 months to arrive at my place from the time I ordered, and there were 2 weeks of delivery (shipped November 19 and received today).

Now that someone got one I'll spill the beans on mine. In a round about way I was able to get one earlier this year. I wish I was able to get the gloss black like Robin but had to settle for matte black. I have 1490 miles on it so far. I got the medium. I'm about 5'8.5" ( wingspan of 6 ft). I might have been able to get a large but I wasn't sure if the seatpost would be too long to run a dropper. I'm running 740mm bars and an 80mm -6 degree stem. I wish it had a little longer reach. Height wise I'm right on the edge between a medium and large and I have a long reach as stated above. But a frame with long reach is no good if the standover is too high for my legs
I built it up around a 120mm Sid Ultimate. It's last year's with the 32mm stanchion. The shock is a 165x45 fox nude from a 2017 Scott Spark 920. The rest of the components were budget buys.

I forgot to weigh the frame before I built it up. I think it sits about 26lbs without pedals.
So far I like it. It pedals pretty good. I wish the bottom bracket was higher because I get some pedal strikes. I have it set up with about 10mm of sag on the shock so I probably can't get it much higher. I spend most time with it in the middle shock position so 80mm travel. Not much pedal bob when I'm pedaling normal. Standing up and mashing there is some. I lock out the shock and fork on flats or smooth climbs when possible. I'll open it up for full ~115mm rear travel on rough stuff and when taking larger jumps and drops.
It's my first carbon frame. It feels pretty stiff but I'm only 142lbs so I'm light. I took it all apart when I got it and packed grease in all the bearings and then torqued everything to spec with blue loctite. I have a creak that I think is dirt in the seatpost otherwise the suspension is quiet. I bent a derailleur hanger when I crashed and then broke it when trying to straighten it. I had 1 extra so I ordered a couple more. I sheared the head off a suspension bolt somewhere around 800 miles so I ordered backup hardware.

Are you happy with the combo Mezcal/Barzo?
Do you ride with them in the mud sometimes?
I ride with Barzo for a year now, and found them much more grippy and equally rolling than Rocket Ron's.
-
I had Rocket Rons and hate them so much in the front wheel, they have so few grip. In the rear they roll easy and have decent grip.

I am happy so far with the Barzo/Mezcal. I don't get a chance to ride mud. With the way our soil is, they close our trails when it's too wet and open up once they are dry otherwise the trail surface gets damaged and then holds more water the next time it rains. The closest thing I get to mud is when the top is a little greasy sometimes. There was one night last fall when it was greasy that I crashed twice in corners when my wheel(s) slid out. One time was on a root I think and the other I was just pushing too hard for conditions.

Little update of the building process.
Last components will arrive this week, and I will be able to mount the wheels and finish the assembly.

Is this a bar from Costelo ?
The bike computer mount is just stuck/glued on the bar?

Is that a DIY kydex downtube protector or did you find something that fits well? I tried making a kydex but it didn't form well and looked like garbage. Still trying to figure something out. A giant Trance X has a rubbery one I'd love to get my hands on but no luck so far
-

Yes indeed I bought the handlebar at Costelo, it is the generic version of the Gemini Pröpus in 70mm x 740mm.
The gps mount is glued with a double-sided 3M patch with a diameter of 35mm, just larger than that of the Garmin mount.
I have ridden with this system for a season on my old bike, and it has never moved.

It's DIY with 3M 2228 tape, which I also used to protect the chainstay (upper and lower part).
It's super easy to install, it sticks very strongly and it takes the shape of the frame to perfection, and to the touch it's very soft and with its thickness it should absorb rock impacts well.
-
Here is the list of components with their weight, I have not received them all so the total weight is not yet verified, but I think I am around 9.8kg and hope to go under 9.5kg in the future more or less close.
(sorry for the french spreadsheet, but i think the part names speak for themselves ;) )

The rockshox SID cable pull is 10mm.
What is the cable pull of the Fox Nude shock (12-13mm I guess) ? Do you have a "free stroke" on the fork cable on the first 2-3mm ?
How does it feel and perform ?
Thank you very much

Cable pull is very close between both. I leave a little slack in the fork cable when shock is open. With the remote in the middle position the fork seems to be open. Then at lockout both shock and fork lock out. Overall it seems to work. I was worried I wouldn't be able to get a 2 position fork to work with the 3 position shock and remote but it works just fine.

Howdy!
I am new to this forum. I have built 2 carbon hardtails for my kids and have laced carbon rims to my store bought gravel bike.
I placed an order for the LCFS917 this week. They are already mocking up my decals so I hope the frame gets shipped this week. They either had some extras on the shelf or they are selling some b grades. I certainly hope the former.
-
I was looking for a frame with new downcountry geometry to do xc and marathons. i had seen this 917 but it is not very famous like the riot, 936 or 909. how did you feel with this frame?
-
A great frame if Light Carbon are willing to sell it.

It looks great! What software template are you using to work on paint/decals? Would love to use the same one. Thanks and good luck!

Does anyone know what the spec for the top shock bolt is? I need to find a replacement.

So i have the 919 frame on the way and bought a 165x45mm trunnion shock for it, and looking for the bushings for it. I can't seem to find M10*54mm on Aliexpress. Is it an uncommon standard?

The M10x54 is not a bushing. That is the width and thread on the top of your shock. A grunion mount only has the lower bushing and the top threads into the shock body directly. The frame should come with the two m10 bolts and the bearing will be in the frame. Just put your shock in and bolt it up. This has one hole visible and then another on the other side. Notice there is no bushing eyelet on the top of the shock. https://th.bing.com/th/id/OIP.dY1lJcDRK4CSVubdjO33UQHaFj?rs=1&pid=ImgDetMain

If you need a bushing for the bottom I highly recommend Offset bushings. They are based in the Uk but ship all over and make great stuff. They even make custom lengths and what not. If you need it.
