Latex inner tubes updated

I haven't had good results with Latex tubes and Latex sealants. Maybe if you set it up for each race it would last long enough. But that's the part of the racing game that doesn't interest me. Tubeless lets you go below 30psi. But the plush RH tires ride just fine and roll fastest at 33psi, so tubeless doesn't have anything to offer me. I just want the Latex tubes to hold air, and self seal small punctures. My Ebike experience tells me this is achievable. RH offer his tires in 4 casing weights. Many racers in the harder events don't run the Extralight casings, but the Edurance version. There is also an Endurance Plus for loaded touring situations. So a lot may depend on the specific tire, or specific event being run.

If you want to try the hack I would use the Specialized 2bliss sealant. It's rated for tubeless use, and Latex tubes. It's one of the Glycol sealants, so stays in the tire indefinitely. It doesn't seem to be in the supply chain yet, but it can be ordered.

The Airlock sealant is not bad to work with. It's very thick so a hard push on plunger of the injector tool was required. But since the sealant itself doesn't dry there was no rush to clean out the tool. I could take my time and mount the tire and the sealant still washed out with warm water. The plastic tube provided under the cap is useless. It's crimped in several places from being wrapped too tight. Have another method ready if you try this.
The pressure loss is in a manageable range. RH says fastest rolling resistance at 42 and 33psi (equal resistance) at my weight.
So I put 45psi in the rear, and after 2 days end up at 30psi. But the difference at the other pressure is small. It only starts to get bigger if you play the low psi games that tubeless provides.
