Light weight, and with a little modification, even lighter. Definitely helps with moves where the bike spins (FJWs, whips, spins etc)
Tread pattern isn't too restricting for street riding
Works tubeless
Sidewalls are very thin, and really require to use higher pressures (i.e. 45psi +) unless you like changing inner tubes (or in my experience, buying a new tyre, because you tore the sidewall)
Narrow profile isn't as reassuring as 2.4" in my experience
