The WTB Frequency TCS (Tubeless Compatible System) i23 is the best of both worlds. It’s a strong, lightweight, and is tubeless compatible. The UST compliant rim bead is shaped to help keep tires on rims better. WTB uses their “4D” drilling process which creates the optimal interface between spoke and rim. This exact angle reduces binding and the need for eyelets. To ensure strength and rigidity, WTB uses their I-Beam which was pioneered in 1994. I- Beam is a centrally located vertical support that counteracts spoke loads and provides torsional rigidity. In addition to the I-Beam, WTB embodies an additional band of aluminum to the sidewall that improves torsional, radial, and lateral strength.

Comments about WTB Frequency TCS I23 29'Er Rim:
Lighter than the stock rims they replaced (though not too much lighter) I have a set of these on a hardtail and they are still true after some nasty rocky conditions with plenty of drops. The bikes frame is another story... Tubeless ForTheWin
