The Flexy’s thick, linear pin tread is built for clean and clay tracks where grip is at a premium, biting hard into compacted surfaces for consistent forward traction and confident cornering. This pair comes pre-glued onto GRP’s white wheels, ready to race straight out of the bag – no gluing required. Part of GRP’s Italian-made Ai-TECH range. Available in five compounds: N25 Super Soft (Clay), N35 Soft (Clay), S25 Super Soft (Dirt), S35 Soft (Dirt), and S40 Medium (Dirt).
