Tioga Powerblock 20" BMX Tyre

The PowerBlock is a top-tier BMX racing tyre engineered to maximize pedal efficiency and rider input, translating into quicker, more effective lateral movement. Featuring a steel bead and reinforced sidewall, it balances durability with performance. Its unique sidewall texture enhances abrasion resistance while maintaining flexibility. The tyre’s distinctive three-stage tread design, refined through an 18-month rigorous testing process with elite fast2 racers globally, ensures superior grip and control. This standard PowerBlock model offers an optimal blend of high performance and value for serious BMX competitors.

KEY FEATURES

The outer knobs : The outer knobs, measuring roughly half the length of the transition knobs, are engineered to provide optimal compression and traction when leaning beyond 25 degrees. While usually unnecessary in a smooth race, these knobs become crucial in challenging conditions, maintaining grip during aggressive turns and maneuvers. This ensures you retain maximum control and traction, helping you push through tough sections and cross the finish line quicker.

The centre row "Power Block" :When accelerating, the rear tyre’s central tread zone receives intense pedaling torque. If the center knobs are too small or tall, they flex and compress excessively, causing the tyre to grip the ground slightly longer before releasing, which wastes energy—excessive traction can hinder performance. On the other hand, if the knobs are too large or short, the tyre may slip under heavy torque before regaining grip, resulting in a loss of speed. Balancing knob size is essential for optimal power transfer and acceleration.

Each Power Block is proportionally sized to handle the torque without sticking and perfectly balanced with the proper height to minimise slipping all while retaining very low rolling resistance after take-off.

The transition knobs :The transition knobs, significantly smaller yet precisely proportioned to the center blocks, are engineered to slightly deform at lean angles exceeding 15 degrees. This deformation, or compression, allows the rubber to "stick" to the ground, enhancing traction. Positioned at a 45-degree angle relative to the center knobs, they help preserve forward momentum during lateral transitions and cornering.
