Frame quality from the pieces I've seen is quite good.
It's not the most eye-catching frame though. But there are worse.
Weight is just as announced. You'd just need to add paint in case you want but that should not go over 100g
So it all depends on how u spec it up. Last one I did for myself was pretty light. Shimano 7020 with some 1330g wheels.
It's pretty confortable with 32mm tires

Biggest inconvenience is really the stupid derailleur hanger. Other than that is at any bigger western brand level
I also confirm that the bike is great—easy to handle and responsive, definitely on the stiff side.

I can confirm the issue with the hanger as well—I hate it! It's a shame that Lightcarbon doesn't do anything about it. I believe that with a different hanger design (without changing the frame's mounting area), this flaw could be fixed. Too bad!

Has anyone experienced issues with the seatpost clamp and saddle? Mine makes a creaking noise when I apply some watts on the uphills. I haven’t applied any grease since the saddle rails already have a designated clamping area. 

Does anyone have any tips or advice? Here's the saddle I’m using:https://es.aliexpress.com/item/1005006893754548.html

I had the same problem and solved it by applying this paste: https://dynamicbikecare.com/collections/grease-workshop-1/products/assembly-paste-pro

The only noise here is you.  You wanting to dictate what others say and think is fkn odd.

Can I ask what the problem with your frame was? Mine arrived in perfect condition: the quality of the carbon was excellent, the paint flawless, the bearing seats perfect, the bottom bracket threads perfect, and last but not least, the faces where the brake calipers rest were milled and perfectly parallel, or rather, perpendicular to the brake discs. It has never been so easy to align brake calipers... The result of your crusade is that everyone who has had a good experience with the frame will write it here, haha!

Hi Guys,


I'm looking for a pretty aggressive and stiff all-out race frameset, I'm looking at a LCR017-D or a Winspace T1550.

I love the idea of both these bikes and I've heard rave reviews about the aggressive geometry and stiffness of the T1550.

I'm more interested in hearing about the characteristics of the LCR as it's more attractive on the wallet, how does it ride? how stiff is it? Would it make a good all out race frame?

Thanks!

I'm not really qualified to answer since I've only owned three road bikes and have never raced, even though I've ridden around 50,000 km in the past six years. Compared to the 2018 BMC Roadmachine, the LCR017-D is definitely more responsive when sprinting and generally a bit stiffer. However, with its slightly slacker fork angle, it's easy to handle—it's not twitchy at all. The geometry is certainly aggressive.

I’m not sure if this helps, but that’s my experience with it!

I spent a significant amount of time riding side by side with friends on flat terrain, and as someone who pays close attention to power data, I feel confident that this bike doesn't come with an aero penalty. Based on what I've read about aerodynamics, the downtube is positioned in the 'dirty air' created by the front wheel, so having a slightly less aerodynamic shape doesn’t significantly impact performance.

I would also add that the biggest impact on aerodynamics comes from the cyclist and their position on the bike. However, it's true that I was looking for a stiff and lightweight frame, easy to handle on climbs. That said, with this bike, I’ve improved many of my personal records, even on flat terrain.

The drag would have to be insane for you to be able to hear it.
A bus isn't aero. Therefore, that downtube can't be aero. Would you be faster on a kamm tail shaped down tube? almost certainly. Would you EVER see a bus shaped downtube on a TT bike? No. Do you see kamm tail shaped downtubes on TT bikes? Pretty much 100% of the time.

Now, does it matter?
If you like your bike, great.
From my perspective, most of my riding is done on the flat, so i do care if i can save 5w at 40kmh, because i often ride at 40kmh.
And from the perspective of people considering the frame, they should know that this feature can't possibly be fast. Whether it matters to them or not, is for them to decide.
Lovely bike!

Easy, just don't buy It   :D

Has anyone out in the real world been able to quantify whether or not the square downtube is actually causing significant drag? Meaning, does the riding dynamics on road feel draggy? Can you actually tell?
Since I'm a cyclist and not an aerospace engineer, I don’t have access to a wind tunnel to measure these things. What I can say is that my bike performs perfectly in all situations, even on descents at 80 km/h. I've never noticed any weird noises or whistles like the ones you get from roof racks on cars, so as far as I’m concerned, the square downtube isn’t a real issue at all.

Do you have other road bike for comparison purposes? On the fence between this and SC-R55...

I own a 2018 BMC Roadmachine size 54 and a 2011 Kuota Karma. There is no comparison with the Kuota, whereas compared to the BMC, I can say that, in terms of ride quality, I haven't noticed any significant differences. In fact, I actually prefer the LCR017 because I built it to fit my measurements. The geometry has a slightly longer reach and a lower stack. Surprisingly, I feel more comfortable with the lower stack, which is about 3 cm lower. As for the reach, I compensated by shortening the stem.

The frame I received is of excellent quality, and the assembly went smoothly. The BB on the LCR017 is a T47-68 mm, which threads into the frame and is easy to handle, whereas the BB on the frame you're proposing is a press-fit type, which is a bit trickier to deal with.

I wouldn’t underestimate the issue with the rear hanger. If you do races and need to change wheels quickly, I think it's better to avoid the LC frame. Otherwise, the issue is almost negligible, though personally, it does bother me a bit.

Here’s mine, 7.3 kg of poetry haha, just kidding, but it really is a pleasure to ride. The only real issue I've had in these 4 months and 3000 km of use (it's already done Stelvio and Gavia) is with the derailleur hanger. When I remove the thru-axle to take off the wheel, the hanger doesn’t stay in place but rotates, pulled by the chain, pivoting around the screw that attaches it to the frame. I find this a bit of an annoying problem, especially when putting the wheel back on the bike after a flat repair on the roadside.

I'm a bit surprised no one else has reported this issue before. I’ve already contacted Lightcarbon, and they just said it’s normal, but I’ve never seen anything like this on other bikes.
