The ultimate BMX racing tyre, the PowerBlock is designed to efficiently transfer pedal power and other rider inputs into lateral motion. In short, you'll roll faster with less wasted energy. The S-Spec version utilises Tioga's thinnest sidewall for maximum suppleness and weight savings. Size for size, the PowerBlock S-Spec are one of the lightest BMX tyres in the world.

Features
- Centre row - “Power Blocks” are precisely sized to balance traction with low rolling resistance.
- Sidewall texture - Specially designed texture pattern, strategically applied to the sidewall, adds abrasion protection without sacrificing casing suppleness.
