Lightcarbon LCR020 35c clearance aero frame

[Bonus79]

I also don't love how companies in this price range insist on bright and bold measurement markings on the seatpost.

Thoughtful to have but way overdone. My ICAN Graro is just as egregious

Hi Patrick,

after reviewing the XMCS VRT and the Quick Pro Er:One, do you plan to test the LCR020 as well?

It would be very interesting to see whether the lower price of the LCR020 corresponds to an equivalent level of quality or performance.

Thanks

What does that mean?

Perhaps I didn't express myself clearly... what I meant is that it would be interesting to know if, given a lower purchase price compared to VRT and Er:One, it is possible to achieve an equivalent level of quality/performance, or, if not, how much of a gap there might be.

Don't know if these have been shared yet

It looks really great. Very close to XMCS isn't it?

XMCS has really got crazy - I would pay this price if the after sale service was on par and available locally

kind of. THE VRT is a lovely bike. would love to try one. the LCR020's headset area is a bit leaner, also the fork. that's why i chose it. Also it is like half the price. and i'm cheap  And i love my LCR018

I think most of the difference comes from 2 places. I believe the carbon used is different between the two frames. XMCS using more expensive high modulus carbon. Hence the weight difference. Second I believe XMCS is monocoque while LC is not.

If you factor out weight, I see no reason why this frame couldn't be a could not be on par in terms of performance. It will come down to their layup. This isn't LC's first time making a bike, I would imagine they know what they are doing. More cheaper carbon will add weight but can provide the same stiffness.

Both frames are "monocoque".
The XMCS frame is one-piece monocoque.

What you say is true; I have no doubt about the quality of the LCR020 frame. However, I would be interested to hear from someone who has tested both frames if there are any noticeable differences in how they perform on the road.

Even @patliean1, in his videos, noted differences between the VRT and the Er:One, even though he claim that both are excellent frames. I suppose, therefore, that if he were to test an LCR020, although similar to the other two frames, he would still notice some differences.

I agree I would love to see a comparison from someone who has rode both frames. At this point, we can only speculate, as the LCR020 hasn't been sent out to anyone yet. They are just getting through production of the first size.

For those curious like I was, I reached out to LC about the size 470. The listed STA is 74.5* but in reality it is 79.5*. Not sure on other sizes, I was only concerned about the 470.

[naisenberg]

the 'effective' STA would still be somewhere in the middle between 74.5° and 79.5°, right? since the steeper part is still offset behind the bb

[Dark17]

I think this is correct. I believe it would be something around 75° But we would need to know the BB offset measurement for exact numbers.

[JensenMacD]

My thought based on the information is the following. Virtual STA of 74.5* and Actual STA of 79.5. But as you point out, the actual STA does not cross through the bottom of the BB but offset behind.

My thought is taking the distance of the offset and you would have to subtract that from what the actual STA pushes you forward. IF 79.5* moves the saddle 60mm forward and the offset is 40mm, then the saddle actually only moves 20mm forward.

Note I do not know if that offset is 40mm, I picked a number for my example.

[Timuk]

The actual seat angle on this style of frame will depend on saddle height - the higher the seat post at the 79.5 degree you quote, the closer the overall angle gets to this.  In reality seatpost set back / inline would also materially impact the effective angle.

I inquired about the HBR20 for my LCG072 order and speaking with Joy, the design is not finalized yet and encouraged me to get the HBR18. They didn't provide any timeline for the HBR20/LCR020 to me though.

I hope it's compatible with the 072 and will probably order it once it's out.
