CHALLENGE’s handmade BABY LIMUS TE S is an all-around great tire on soft pack to sticky mud. An aggressive natural rubber tread pattern features lower knobs in the center for speed, higher knobs on the sides for fast cornering. The supple SuperPoly 300TPI casing gives you precise control at low pressures and is water-resistant; no need for external sealant. CHALLENGE’s famous SEAMLESS LATEX Tube reduces rolling resistance and is protected by PPS (Puncture Protection Belt) between the tread and the casing. Removable Valve Core.
