Here are a few pictures.

I weighed the frame and fork on the kitchen scales ;-)

Frame: 911 g
Fork (uncut): 436 g

I think these are outstanding values. Especially as the whole thing has been painted.


Also attached are the desired detailed pictures.

What size is the frame and is it the superlite version?

54 / Superlight.


910grams for a painted size 54 is insanely light!?!  Are you certain the scale is calibrated?

Some newest photos of LCR017-D with T47,
weight A, the weight of only frame is about 910g.

Of course I'm not sure. It's my damn kitchen scales.  ;D

But since the manufacturer specifies 910 g, it should be about right.

dinorello

Manufacturer says the 54 is closer to 950grams unpainted plus at least another 150-200grams in paint.

I can confirm the weights. I also have a 54 cm super light and (again) kitchen scale says:
Frame incl. rear hanger: 926.5 g
Fork (uncut): 406.9 g
Handlebar: 329.4 g
Seatpost: 164.9 g

Wow.., guess less is more!  Wouldn't have figure a manufacturer would overstate the weight

This is my first "build from scratch" bike and my first bike with fully internal cable routing. I have two questions, hope you can help:
After installing everything up to routing cables through the handlebars, I noticed a gap between the frame and the cover under the stem. I believe it derives from the ring guiding the cables / hoses (see picture). Is this normal? Did I do something wrong? Should I do something about it? Anyone else with the frame having a similar experience?

And: do you recommend greasing the hoses at least a little bit? I haven't found anything about it but it seems useful to me as it makes the movement when turning the handlebars "softer".
Or is there something - like chemistry - speaking against it?

Thanks a lot!

That gap seems a bit large,  are you positive that all the parts in the headset are installed correctly? It seems that light carbon includes parts for both full- internal and semi- internal hose routing.

The space looks about the same if you compare to the screenshot of the video lightcarbon posted of the lcr017d

I wouldn't worry about greasing the hoses but would definitely install some foam tubing to keep the hoses/ cables silent.

heljan

Thank you, dinorello.
What video is that? Do you have a link for me?

I am not 100% sure about the headset, might need to chat with Wendy once more ;) It's pretty tight with SRAM hoses so I was considering using a bit of grease to make sure things are moving when putting everything together.

Thanks for the advice re foam tubing. Actually used exactly the product you are recommending  :D

I don't think that this video should be seen as an good example, because the bike is obviously not assembled completely. I assume that fork and headset will have a massive play with this kind of gap. Or, if everything is well compressed sand without play, a washer or the compression ring is out of spec.

I don't have this bike, but worth noting that the specs for FSA ACR and Deda DCR headsets are ~4nm of preload, not the ~2nm that most people are used to with traditional headsets.

Also would NOT use grease on cables it will attract dirt and make a nice griding paste in your frame.

That last spacer should not make contact with the frame at all. The compression happens with the metal pass-thru washer that's resting against the top bearing at the head tube.  Either that pass thru washer should be thinner by .5mm or that final plastic spacer should have a deeper well to cover more of the pass thru washer as per the last pic
