Quick update on the seat stay nut issue: I've just received a replacement from LightCarbon and they've updated the design to fix the issue. The nuts are now completely captive and built into the seat stay during the layup process. Looks like a great fix!

The bike looks amazing man!!

I got some questions for you!

First what size did you go for? I am 6' and i went for a large...

What length dropper are you running?

How does is ride (Are you on a 29 or 27.5 setup?) I am wondering if its long wheelbase and slack HA makes it feel like a tractor when riding less steep terrain?

Finally, how much steerer tube do you need on the fork? I know the HT is 100mm on the large but how many spacers do you run?

Cheers,
Simon

First of all thanks!

And for your Qs:

I'm 6'2" and went for a large, the frame size has felt great so far.

Dropper is a 150mm from PNW, you could possibly get away with a 170mm from OneUp as they have the smallest insertion depth IIRC but I didn't want to chance it.

I've got 29 wheels on it and love how it rides, I know some folks like the snappy handling of smaller wheels and shorter front ends but that's not for me. The geo definitely shines when it gets steep and especially when it's chunky, I've got a 170mm Ribbon Air in the front so it feels like it can plow through anything. As for feeling like a tractor, I don't find it sluggish on flowy stuff or pedaling-heavy sections. However, it does have a ton of trail with the long front end and you absolutely notice it when turning, especially at low speeds. I notice it most when slowing to navigate trees that would take out my bars if I'm not careful. That is the tradeoff of the slack HA and I feel it's worth it but it's something to keep in mind.

For the steerer mine is real short, I don't know what its cut to exactly but I run 25mm of spacers and a 34mm tall stem.

Hope all that helps and good luck with your build!

Hey all I'm the one who had that issue with the linkage bolts, LightCarbon is sending me replacement seat stays under warranty with their fix. Wendy mentioned something about making the nuts captive so they can't move in the housing on the seat stays. Can't comment on how it'll work yet as I haven't received the replacements so far.

I did end up finishing the build anyway just to see what it looks like while I wait for those replacements. I went with spray.bike for the paint and did it myself.

I'm curious what your plan is for frame prep.

I have one of these on order also, and I also want to paint mine. I'm looking at the Spray.bike paints. I plan on using the carbon primer - but I'm wondering if the factory surface needs much prep.
I am assuming 800 grit wet sand and then ready to go.

Maybe to release these bolts you can either dremel a slot and use a flat head or drill some holes and use a spanner, something to give you purchase on that captive nut other than the carbon?

I've ordered colors from spray.bike for my frame and am planning to just wet sand then paint like you mentioned.

Update on the captive nuts: the carbon cracks immediately on loosening the pivot bolts, light carbon has told me they'll send me replacement seat stays. If they're the same design I'll probably end up machining new nuts with 6mm heads so I don't rely on the   carbon anytime I want to disassemble the rear triangle.

Have any of you who've built your frames run into an issue with these pivot bolts? The nut end of them is only held in place by the carbon at the corner of the rear triangle and it looks like it'll crack when I go to loosen them. All the other pivot bolts I've removed so far have been really tight also with tons of blue loctite on them.
If I wasn't planning to paint the frame I would just leave them as they're clearly pretty bomber and don't seem like they'd ever come loose.

I was able to order an LCFS947 in early September when it was still listed on both the LightCarbon and YishunBike sites. They quoted me two months lead time then but that's been extended to three months now. Once I receive it I can share pictures but it looks like if you haven't ordered one already they're not selling any more pre-orders.

I'm curious if any others in this thread who ordered early this fall have received a frame yet or have all orders been delayed til sometime in December like mine?
