Do you have any tips?

Grind the contact area with a coarse grit. After I did this I had no more skidding.
Btw the same goes with the seatpost clamp. After I sand it down I had no slippage anymore, almost as good as the new designed clamp.

The saddle tilts under load. I’ve already tightened the clamp quite firmly, but I was careful because of the carbon struts (recommended torque: max. 5 Nm).

Step 15 "Install the saddle and tighten the seat post clamp bolts to 8–10 Nm"

I use Ryet saddles and no issue yet with 10nm.

Yes, I'm familiar with Lightcarbon's instructions. The 5 Nm is the torque specified by Ryet for that specific saddle with carbon struts.

POTOOOOOOOO

They technically specify the 5nm for yolk style seatposts. A full clamp such as the 18D is much higher

hello all,
wonder about the frame sizes to body high
I am 1,80m with 84 Leglength, my former frames are
Planet X Tempest Size L    stack 587  reach 395
Cube Agree 2020 Size 56  stack 573 reach 390

The geomtry and size chart for the  LCR018-D says for 1,80m
size 540 for 1,80-1,86m with stack 569 and reach 383
size 560 for 1,87-1,93n with  stack 586,8 and reach 389 

Would choose the 560 frame with short stem 100mm and both seat posts with and wothoz offset , but now i am not sure ...

What ist your body hig and what frame size do you use for the  LCR018-D

Thanks and kindest regards
Frank

It appears there are a few people in this thread that are running mechanical on this bike. I have an R7000 Ultegra setup currently and fancy keeping it for now as nothing is wrong with it and I've had no shifting issues. I've seen some tips about cable stops etc in the threads but if anyone is reading that is running a mechanical groupset, any extra hints or tips? thanks

I'm in the same situation with 1,84m. Lightcarbon recommanded me 54 without any doubts:
"Engineer Verdict & Complete Optimal Build Spec (Comfort-First) for you:
Best selection: LCR018-D Size 54  (56cm is not recommended)
Seatpost: 15mm offset
Cockpit: HBR17 integrated bar with 110mm stem length, 10mm total headset spacers (2×5mm)"

This all really confuses me, I've had a huge dilemma with the bike frame size. my current bike I feel fits me well other than wanting perhaps a shorter stem but comparing geometry it seems to always come back to a 58.

I am 188cm tall, 87 inseam to barefoot on the floor. Not great flexibility.

I compare my current bike (blue) to the LCR-018D in a 58 (red) it matches closest, 56 is a lot smaller. I was going to buy 58 with a 110cm stem and 0 offset seatpost.

I had a bike fit on my current so it seems like going with a similar size would suit me. Sadly it was 9 years ago and all done on paper which I've long since lost and my bike fitter didn't keep online records.

If it was 9 years ago that old fit is irrelevant. Get another one.

My concern with that is the double cost as I'll need another once the bike is built and funds are a little tight. Obviously buying the wrong frame is also more expensive. The 56 is quite a lot smaller which scares me!

You can get a pre-purchase bike fit. They basically replicate the bike's geometry on a special fitting bike, and from there they determine the exact frame size and all the other measurements, such as saddle height, stem length, handlebar width, and more.

That way, you can buy the bike with the correct dimensions and set it up with the right number of spacers from the start. It saves you both time and money because you won't have to keep experimenting and swapping components. I think it's your best option if you're not sure about the right measurements.

Exactly.

I have no idea why people guess the size and then spend far more money buying different seatposts and bars to you and dial in a suitable fit.
Get the fitter to do the work and it’ll cost less and you’ll have a far more enjoyable experience.

well, which of the 2 existing bikes do you like more and why? 

which issue (stack or reach) is most important or limiting?  usually it's stack, so i'd pick the size of the LCR that addresses that issue best.  and then accommodate for the other (reach) with bar choice.  so if stack's the priority, then pick the LCR size that matches the stack you want and you can shorten or lengthen the reach with a shorter or longer stem bar.

asking what random people on the internet picked, even if you're the same height, may not be helpful since everyone has different flexibility, longer arms vs longer legs, preferences, etc.

but your plan for a 56 sounds reasonable

Stack and reach are interlinked - get a 56 and add spacers will shorten the reach. Depending on the amount of spacers you add, you may need a longer stem to compensate.

It’s gets complicated - hence suggesting a pre bike fit.

I'm 183cm, and have the 560. Feels perfect.
