Ultra Lightweight and fast-rolling, the 120 TPI, 100 PSI tire provides incredible grip.

With a Kevlar bead and high-pressure casing, the Siren can be inflated up to 100PSI for ultra-low rolling resistance on smooth surface riding. The reinforced sides keep the casing from flexing as you carve, and allows you to track a perfect line. Combined with a high-rebound compound, this gives the Siren an incredibly low rolling-resistance.
