Tioga Powerblock 24" BMX Tyre

The outer knobs : The outer knobs, measuring about 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 excel 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 reach the finish line quicker.

The centre row "Power Block" : When accelerating, the rear tyre’s center 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 crucial 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 to the center knobs, they support maintaining forward momentum during lateral transitions and cornering.
