The ZTTO BBs aren’t really a better deal than Wheels Mfg because the bearings are terrible and need to be replaced almost immediately, which ends up costing about the same as just buying Wheels’ thread-together PF BB in the first place. But with extra time and effort.

Have you had much time on these?  Do the decals look to be under the clear coat or can they be pealed off?

Thanks for the replies all. Since I wanted tubeless and these are probably not that, I went ahead with tried and tested Panaracer GKs from a bike store that's closing down. I will eventually order the 40c and put them on a reserve rim set.

Yes 25c and 28c are both 350g/tire per the description. Never weighed my other road tires but that does seem heavy.

I made a conscious decision not to purchase American Classic tires.  To me, they need to come clean and disclose more regarding where they manufacture their tires.
I don't care if they are made in China if they are open about it.  But their website still has no contact phone number or state anything about where their tires are manufactured.  Perhaps someone to has purchased American Classic tires will look on their tires and see where they say they are manufactured.
