VeloFlex Sewups vs. Air loss

[TopCarbon]

I usually use Tufo or Continental sewups and recently wanted to try a new tire. I purchased VeloFlex sewups and glued them up. I can go a couple of days without feeling a difference in air pressure with the Contis and Tufos. The Veloflex are almost flat a week on.

Is this the experience other have with these tires?

Veloflexes use latex innertubes, which are naturally porous, so they will leach out 10-20 psi nightly. Latex tubes are a bit lighter, and allegedly more supple than butyl tubes.

Veloflexes are great tires.

ahh, that explains it.

Thank you
