New Light Carbon LCSF980 XC bike
bosbik:
Jim also replied and said the same thing frames arw Z3 level so thats really pushing me to pull the trigger
gf:
What do you mean with Z3 grade? Does Lightcarbon offers different quality for the same frame?
federic000:
More than 2kg without ammo yes it’s heavy I hope it’s strong at least
repoman:
I should've weighed my frame before building it.
My build is at 25.1 lbs with 2 weight weenie parts (lexon crank and transfer SL dropper) and 1kg downhill/enduro tires. Wheelset is 1400g. I think if I put some 650g XC tires on and an XTR cassette the weight would be around 23.3 lbs.

I found this in the handle bar when trimming to length, dunno what to make of it. The carbon feels like it has no resin on the surface of the interior. I can feel the weave and pick at it. There aren't loose threads but I can feel the texture of the weave. Anyone know if that is normal? Never seen that on handlebars before. Cross section of the tubing looks very solid. :o

The best quality is to not see any resin inside the handlebar. The high quality we pursue is that the resin does not leak out at all, but is all inside the carbon fiber layers.
Regarding BB, I'm sorry. The bottom bracket is pre-embedded into the carbon fiber frame. Resin may overflow during high-temperature molding, or one or two threads in the purchased BB are not deep enough (usually we will check before using these aluminum alloy accessories, but they may be missed), resulting in the need to manually deepen the threads again. We will improve quality inspection standards in the future.
In addition, we have added an inspection step. During packaging, workers will use tools to try installation again to confirm that the threads are correct.
