Re: Lightcarbon: LCR018-D (endurance all-road) I think the conclusion is only partially correct — LightCarbon does actually publish parts of their testing protocol:

https://www.lightcarbon.com/testing-process_n23

From that page we know their stiffness tests are based on lateral deflection under load (N/mm), with defined lever arms (~250 mm head tube, ~260 mm BB) and minimum thresholds (100 N/mm head / 120 N/mm BB).

So the values are grounded in real structural testing — not purely marketing.

However, direct comparison with Roadbike magazine (or other labs) is still problematic because stiffness numbers depend heavily on fixture design, load position, and measurement method. Even using the same unit, different protocols can produce very different absolute values.

Most likely the published LC figures (117 / 185) are normalized indices derived from internal N/mm measurements — useful for comparing LC frames internally, but not 1:1 vs other brands.

As if a magazine that mainly depends on advertizing and major brands sending them stuff for testing will run any unbiased tests on any direct-to-consumer Chinese parts. Let‘s not be naive…

And let‘s not forget that half of all comparative testing is won by Canyon bikes, all of which I‘ve had in my workshop are just utter crap.

Two things: While its plausible that an entity that depends on advertising could be biased towards its advertisers, that plausibility is not evidence that they are.

Secondly, whether they print fabricated data to the benefit of their advertisers or not, where is the logic that suggests that this would have any impact on the comparative data across brands that don't purchase advertising from them?

Do we know the maximum system weight for the frame?


I was told 120 kg when i asked Hedy at Lightcarbon.

I'm wondering if anyone could advise me on a frame size and handlebar combo. I am really, really struggling to decide what size to get.
I am 188cm/6ft2in.
90kg but hoping to drop a few KGs with cycling!
Not super flexible, I get some shoulder pain over time with my current bike
Wanting an all day comfort frame.
My current bike is a sort of off brand from a UK based retailer called a Hoy Alto Ipravi .001
I put it in a geo comparison site vs the XL/580 LCR but maybe you guys can give some more insight. I did have a bike fit on my current bike and it seems OK for me but it's been my only road bike.
https://geometrygeeks.bike/compare/hoy-alto-irpavi-2016-xl,lightcarbon-lcr018-d-2026-xl-580/

I am leaning towards the 58cm frame, 420/110 bar/stem.

Thanks!


Not too sure why you’re deliberating on this if you’ve had a bike fit. If it was recent, just ask the fitter what size to go for.

Remember to add 8mm of stack for the bars and another 8mm for the mandatory headset bearing cap.

I'm awaiting delivery of my LCR018D. What headset bearings did you get from Amazon?

Re: Lightcarbon: LCR018-D (endurance all-road) STEGPB: Computer mount comes as standard with handlebars it is pretty good computer mount, but if you have small bike computer it is a bit long, that is a difference in that 3d printed one it is a bit shorter for garmin 5xx.

Re: Lightcarbon: LCR018-D (endurance all-road) similar stuff used for cars to protect from chips and scratches. ridewrap is a name brand version for bikes that is custom cut for popular bikes (ie tarmac, etc).

the paint from LC appears really great…smooth, thick clear coat. i’ve had used steel bikes with a bunch of chips and scratches in the thin clear coat i wish had paint protection. so this paint protection film may be overkill. but for a few dollars and some time for a brand new frame, i figured i’d do it.

it’s generic but the pieces fit my 56 frame well. youtube some tips and instructions… i used the wet method. it comes with a little spray bottle and squeegee so pretty comprehensive package for the price.  also used hair dryer for tougher corners to help mold/stretch the film.

used a relative cheap ceramic hybrid spray coating i use on the car… just spray some onto a corner of microfiber towel and wipe and buff the entire frame after applying the film.  should help keep repel sweat, dust, water, etc off the frame for a bit.

Can you support with product names? Received my frame, would like to do the same, but no experience.
