Лого УСТ нету.
Нафига УСТ, если и так все работает

Главное - сделали корд правильный...
Прошлый фаст трак у меня был тру-УСТ. С лого и т.д.
После Куяльника без герметика спускал быстро. Так что УСТ, не УСТ - практически по барабану

Особенно, если с герметиком.

"2BLISS MTB TIRES
There's a reason why our MTB pro team rides 2Bliss tires-they want a tire that can handle the low pressure they run (sometimes 25 psi) for durability and better traction, but they also want light weight. Specialized 2Bliss blends the best of both worlds. It's not your standard tubetype (TT), which is lightweight, but can fall short on puncture resistance and "burps" when used with sealant. And it's not your standard tubeless (UST) that reduces pinch flats and the need for sealant, but often adds 200+ grams. 2Bliss is a whole new design that uses TT casing with a special UST bead, replacing the standard UST heavy backing with strategically placed rubber only around the bead. The result is a perfect tire for the discerning MTB rider: low pressure allowance, no burping and fewer grams than its forefathers."
