Lightcarbon: New LCR017-D (or Yishun R1058-D)

[dinorello]

Hopefully lightcarbon will address your issue asap as I wouldn't feel safe riding that.  Makes me wonder about my own frame as I never used an endoscope to check it internally.

Check your invoice. I ordered Grade A. Should be the same as you. I didn't find such problems in mine. Maybe you had bad luck.

LC is quite responsive, so I'd wait a couple of days for their answer before raising it. In my view, as I mentioned in other threads, it's not about having 0 problems, but how companies solve them.

LC has been working on their reputation for some years. Those voids don't seem natural at all.

Grade A. The new z-tier classification is the new way to sell crap at any cost keeping reputation high

what's this new grading system about?  I bought a MTB frame recently from LC, but didn't see any grading mentioned in the invoice.

If you don't get a response you need to open a dispute with PayPal for the full purchase amount including shipping and duties paid.

It's all about the QC.  The more you pay the more QC will be performed.   On a retail level there's no leverage so it's all buyer beware.   

[dinorello]

I agree completely but without a forum to voice a complaint it's ultimately up to the buyer.  I don't know what happens psychologically but a lot of people feel shamed in voicing their complaint. Sellers know this and try to flip the script and turn it on the buyer, in my experience that is.

One takeaway from the grading scale is the sample rate for QC.  I know everyone who drops a couple thousand dollars on a frame would love to believe it has been finely inspected in the factory, but the reality of QC is that you need to define a sample rate and have a process that is capable.  A more frequent sample rate is expensive for the labor to check, but it lowers the probability that process went sideways during the production.   It doesn't eliminate the chance that problems happen. 

I hope LightCarbon addresses this frame and replaces it.  I do think a lot of brands buy with smaller QC sample rates but rely on after market warranty to take care of issues when they arise, or they put in their own post-production inspection to return frames not up to brand standard (but this seems unlikely to me/or at least is a sample rate that is not 100%).

As we are making philosophical tirades, let's go on the tangent of critical thinking.

I am Swiss from the French speaking side and I hold a French passport so I kind of like to hate/be critical of our beloved dysfunctional neighbor third world country [France]. (our national sport).

Given the media exposure of conspiracy theorists and the support from the people to politicians financed by authoritarian countries, we can be skeptical about the practical impact of putting kids in mental masturbation torture about arguing why pedophilia could be reasonable [it was real topic asked to high schoolers for their final exams

[dinorello]

We're living in the information age and that in itself can be leveraged to affect people's narrative and actions. Be it buying a bicycle frame or choosing a president each person believes that they have agency over their thoughts, emotions and decisions.  Call it marketing in a commercial context or a psy-ops military campaign to affect an outcome do we really know if our strings are being pulled?

[neobiker]

The question is then what has been showing to consistently manage to fight information manipulation?

Critical thinking/skepticisim/scientific method.

Basically, we have to agree on how we get to the same fact if we disagree on what we observe, and decide what can be decided and what not.

Question to you guys since it's not clear for me. On their webpage they recommend a 4/5mm gap between the top of the stem and the expander plug.
In all my builds i used 4/5mm not to the expander plug but to the fork cut. Which, after putting the expander plug usually results in sth like 1mm gap.
How are you guys doing this on this frame?

[rasch]

Usually I'm able to have it with 1 or 2mm. Was just wondering if this one actually was different because I have a feeling of slight play, but that mght be due to the front tire being super wide and "moving". Can't say 100% whether it's play or not.

[rasch]

You mean those small spacers? Sorry didn't get which plastic parts you are talking about

[Ar26]

This is the part that fits over the upper bearing. Another thing not to neglect is the tightening of the expander in the fork. Sometimes it is not tightened enough and when you compress the steering cap, it tends to go up
