In addition to the superior puncture protection it features many inner values: ROLLING RESISTANCE: The patented, 5 mm thick SmartGuard layer, when compared to all generic products, has a significant advantage in rolling resistance. RECYCLING: Also in the SmartGuard, we use a proportion of recycled rubber from old latex products. ANTI-AGING SIDE WALL: It now lasts much longer before developing unsightly cracks.
