Cheers guys. Hasnt leaked any sealant but just hisses air in a spots.

Will give it a good spin horizontaly and see if that fixes it.
Same tiny leaking at sidewall here. A good spin horizontaly didn't fix my new pro ones. They dropped from 100psi to 40psi in just 24h.

One of them became better in three days, dropping from 80psi to 40psi in 48h which is kind of usable. Now it is better and better during weeks of using, leaking from 80psi to 50psi in four days and I believe that it's still getting better. However, another one just kept fast leaking which I cannot even ride on it. Schwalbe sealent or Orange sealent both cannot fix it. The seller sent me a new tire at last and I haven't tried that one.

TBH I have never met with this problem before, inclusing old pro ones. Though the performance and ride quality of 2020 pro one is very high, the quality or QC itself is very disappointing.

use some soapy water to find the leak and spin the tire so the sealant covers the problem areas.

So after waxing lyrical about how good these are I’ve got some concerns about the QC as well. Purchased a set of 25s for my Argon, stretched on a rim with a tube for a couple of days the fitted first time with a track pump to my HED 4s. The rear measures 27.5mm all round, however the front measures 27.5mm for approx. 75% of the diameter then it drops to 26.75mm. You can also see the centreline drift off towards the rim at the point by around 1mm.

Weird I know, I presumed user install error so removed checked the beads and refitted. Same result. So fitted it to a different rim with a tube and same again. The wheels in question have had a set of GP5000s fitted previously with no similar issues, so I believe the tape job is good and consistent around the rim.

Will see what schwalbe say...

I just setup up a 25mm version on my front CLX64.(literally minutes ago). I had one pin whole exactly where you are showing yours. Luckily only 1 that the sealent has now taken care of it for me.
