The TIOGA PowerBlock tire is designed for top-level BMX race competition on fast terrain with compact ground, preferably in the rear. Made in soft UTC compound, it features a center tread with smooth blocks precisely sized to balance traction with low rolling resistance. On each side, it has notched and textured crampons to improve grip on slippery surfaces. Finally, a specially designed texture pattern strategically applied to the sidewalls adds abrasion protection without sacrificing flexibility.

• Center band with textured blocks
• Lateral crampons notched and textured at 45 °
• Textured sidewalls

• Bead: Wire
• TPI: 110
• Weight: 430g (OS20x1.85)

 OS20 is not 22" diameter but larger 20" diameter. The OS20 is therefore a higher and larger diameter for stiffness and velocity. It was designed to offer more speed and less rolling resistance compared to the conventional 20 "diameter.
