Designed for the 2008 Beijing games the dth is super light and accelerates like no other BMX tyre. Drop-the-hammer. The first few pedal strokes win the holes hot. The holes hot wins the race. Designed for the 2008 Beijing games, the foldable dth is super-light to accelerate like no other BMX tyre, yet holds up to the abuse you dish out. The dual-compound tread corners incomparably on hard-packed tracks and rolls fast on the straights. The gold medal is just a sprint away.- light weight race tyre- dual compound technology- silkworm protection silkworm technology is an exclusive material incorporated into the casing of select models, increasing puncture and tear resistance. Silkworm is featured under the tread as a breaker (denoted as silkworm)threads per inch (tpi)the number of threads that cross through one square inch of a single ply of the tire’ s casing. Lower TPI gives better puncture, cut and abrasion resistance but is heavier. Higher TPI conforms better to the terrain, offering a smoother, more comfortable ride while reducing the weight of the tire. MAXXIS TPI ratings are the threads-per-inch of a single casing ply, as compared to some competitor TPI ratings. Rubber compounds most important part of a tire is arguably the rubber compound within the tread. By changing the amounts of various components of the rubber formula, engineers can make two identical looking tires perform completely differently. This tyre uses; dual compound - two compounds used within the tread of select tired to offer lower rolling resistance and increased cornering grip. Foldable bead foldable beads keep the tire secured to the rim but are lighter weight than wire bead and easily transported. The bead is made of spun aramid or Kevlar; fibres
