Stan's NoTubes

ZTR Flow EX 27.5in Wheels

There was a time, not that long ago, when tubeless anything was simply referred to as “Stan’s.” While there are definitely more players in the market, Stan’s has remained at the top of the game due to its ease of use, and the proprietary rim profile known as Bead Socket Technology. BST is essentially a square profile that mates more easily with tire beads than a traditional rounded, hooked rim. This means easier tire mounting and bead seating, of course, but also fewer burps, and the ability to run lower pressures.

Those benefits, combined with the rims’ 25.5mm internal width, are some of the most important ingredients for a good, all-around, trail-riding wheelset. The ZTR Flow EXs are laced to Stan’s 3.30 HD hubs via 32 butted steel spokes. The 3.30s offer 30 points of engagement for quick ratcheting over techy sections, and are convertible from 20mm and 12x142mm axles to 15mm and 10mm QR axles with available end caps.
