LCFS948 - a new enduro from Light Carbon

[alexhell]

I will keep an eye on it and if it change anything I will contact them. Its 2 year warranty. And im going to race national enduro series with it.

First impression compared to my orbea rallon r5 after a little ride and jumpig. More poppy, its slack, original geo is with 571mm axel to crown. with fox 38 170 its 63.5 with 76.5 seattube. Floppy in slow pace. Buttery smood initially with good midstroke. Did some 40-50cm drops and there was no problem with bottoming out.

First race done and some serius bikepark laps.
Positiv:

- The frame is durable and can withstand some abuse. Even after a bad landing from a jump, it remained in one piece.
- It handled a 2-meter road gap jump without issues.
- On race day, it pedals efficiently and felt solid without anything coming loose, even after 5.5 hours of training plus 4 hours of racing.

Negativ:

- With 170mm of travel and a rising curve at the end, the bike has a high leverage ratio when paired with a 210x55 shock. This results in the rear shock, a Fox Float X, needing 240psi to achieve 30% sag.
- The rear shock endures a hard life, and if you weigh above 90kg, this bike may not be suitable for you.

hi
why we don't see this frame on LCF website?

[alexhell]

Dont know. I got in contact with jim at Lightcarbon directly to order mine. Took almost 2 month's to get it home.

You can see the specs in the PDF catalog available on the website.

After more riding, both park and home trails. There is two things to keep in mind. For a modern enduro frame stack on the M frame is to low. On the L frame its good. Did end up using 50mm rise handlebars to get same rise as my orbea rallon 2020 to feel comfortable.

Frame is design around 571mm axel to crown that is 160mm forks and all 170mm forks are 583-586 so you end up with 63.5 headtube. If you dont go for 160-160mm instead.

It looks like the "M" is rather on smaller and L on bigger size, there is huge gap between them reach 460 -> 495, normally sizes are by 20 or 25mm. I am "unfitting" just in the middle.

170mm of travel on a 55mm stroke is crazy. You'll need to stuff a few volume spacers in the shock for sure.

yes i use one .6" ³ orange spacer, started with one .4" ³. not to bottom out to hard, best with 55 stroke is 150-160. for 170 it should have been trunion 205-60 or 65. for a better levrage ratio like Scor 4060LT that has a very similar design.

Now with some sweet burgtec 50mm rise to compensate for low frame stack.

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.

Have you been riding your bike, impressions? Any problems with your frame?

So the frame broke.  Took it off a rock roll to 2ft drop and both seat stays broke on landing.  This happened on the second run of a light enduro trail.  Light carbon has been very responsive but not sure what will happen.  More to come.

That is crazy.

could you Share pictures??

I have cracks in my seat stays after one competition and some bikeparking. I have been having dialog with light carbon and they are making a stronger rear triangle and it will be ready in oktober. but i dont trust this frame anymore. Sent a question of refund but i have not received any replies from them on this.

I think the leverage curv is to much for 170mm on 55mm stroke.
