Designed for the 2008 Bejing games the DTH is superlight and accelerates like no other BMX tyre.Drop-The-Hammer.The first few pedal strokes win the holeshot. The holeshot 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 PROTECTIONSILKWORMSilkworm 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 COMPOUNDSThe 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 tires to offer lower rolling resistance and increased cornering grip.WIRE BEADThe function of the bead is to keep the tire in contact with the rim while the tire is inflated. A wire bead is a rigid metal wire is utilized as bead material in applications where ultimate strength is needed and transportability is not a factor.
