Increased strategic placement of Grip-Pods matched to multi-facet Nano Knobs on the shoulder and sides, capped off with friction-enhancing chemical etching over the central tread, FASTR-X strikes the rarefied balance of speed and control like none before.

Features
- Grip-pods - Pressure-sensitive traction system featuring sticky bristle knobs encased within a recess, enabling an ultra-low tread profile with traction coming alive through applied force. Grip-pods activate automatically with natural riding motion for on-demand traction with minimal disruption to forward momentum.
- Chemical etching on tread - Special chemical surface etching applied to centre tread creates fine surface texture that enhances traction on a wider variety of track surfaces.
- Multi-facet nano knobs - Nano knobs in varying angles, shapes, and sizes strategically integrated within the outer tread zones provide additional traction on track surfaces with loose fine grains.
