They are not TB5 compatible though, and if you are going to drive monitors through it, or connect external GPU, 120Gbit (TB5) is much better than 40Gbit TB4 gives you. If you are willing to pay a bit more, consider TB5 cables from CalDigit, StarTech, CableMatters, or Apple.

I used LTT's 40 Gbps cable to connect my ThinkPad X270 to a USB-C monitor and it worked fine. I guess neither device there is TB5, but just wanted to share that those cables do at least support DP-alt mode (or whatever it's called).

I can't find it anymore, but I'm pretty sure that the only reason they don't say it support TB5 is because they would need a license to say so.

You’re thinking of TB4 which only requires 40Gbps.

TrueSpec cables that advertise 40Gbps work fine as TB4 cables.

TB5 is 80Gbps so TrueSpec isn’t capable.
