Has anyone tried the non-5000 grand prix tires? :)
https://www.aliexpress.com/item/1005009505623899.html?spm=a2g0o.cart.0.0.125e38daoLOTBu&mp=1&pdp_npi=5%40dis%21CAD%21CAD%2031.03%21CAD%2020.79%21%21CAD%2019.29%21%21%21%40210318c317545324522045019ebc41%2112000049723162901%21ct%21CA%212135307690%21%212%210
bicyclerollingresistance.com says 4w higher rolling resistance per tire, and they weigh about 100g more than the 5k.
I can get them on ali for $65 a pair or taobao for $40 a pair so a lot more attractive than the $110 or so distributor price ($240 MSRP) for gp 5ks
are these too good to be true or is the extra 200g not that bad?

I've been confused with these same tires. BRR tested the tubeless ready version which has a different construction from the non-TR one:
https://www.continental-tires.com/products/b2c/bicycle/tires/grand-prix
https://www.continental-tires.com/products/b2c/bicycle/tires/grand-prix-tr
Continental's site is basically useless for getting detailed info on tires. It mentions that the TR version uses a 4-ply construction and the non-TR uses a 3-ply construction.
It's my understanding that the TR version has a PolyX Breaker layer for puncture protection which isn't even mentioned on their site. I wonder if that's the missing layer on the non-TR version. Who knows?

I’m pretty sure the ply count is the number of layers the “fabric” of the tire is layered in. The Gp5k is 330tpi, which is marked as 330/3 - or 3 layers of 110tpi. According to taobao the GP TR is 240/4 and the GP non TR is 3/180.
I know higher end tires have higher TPI but not sure as to the effect

Both the grand prix tr and non tr versions do not come with a puncture protection layer. I suspect the non tr version has 1 less layer because it has an inner tube.
I just purchased a 30mm TR version on AliExpress for US$19.42 each with coins and coupons.

You're probably right then. I remember reading a while ago that it did include the PolyX layer but the BRR reference to that was back from 2014:

Nice find, an easy tell if they are fake is if the packaging still claims they're made in Germany. Continental moved their non-5000 Grand Prix manufacturing out of the country, so if it's claiming otherwise, that would be highly suspicious.

That's why this thread has been started. On Aliexpress, the GP goes for the same price as the ultrasport and grandsport and is a better tyre imho as it uses the black chili compound.

I had some 32c gp5000 on one bike and was AMAZED how good they were. Love those tires.
I had some ultrasport III on my road bike that is limited to 25c (max) and they were okay. I recently switched that bike to gp5000 clinchers and... they were a little better. I was almost disappointed that they weren't THAT much better. Almost. They roll a tiny bit smoother and they have massively more grip in the corners (but, in fairness, my ultrasports might have been a little old/worn). Now that I've done a few more rides and longer rides with them is that I now see that they can they roll faster with lower pressure. At higher pressures that I typically run, you really can't tell much difference except for the extra grip you get on the 5000's in the corners. But, now that I know I can run them 20psi lower and not lose much speed, I might be changing that.
