The Maxxis Detonator, with its dual compound tread pattern, provides a durable training tire with a race pedigree. Softer silica compound on the outer edges of the tire allows for great traction in a variety of road conditions. The Detonator is durable enough to provide plenty of winter miles, yet supple and grippy enough to race on in the summer. - M-shaped grooved tread pattern- Silkworm protection- Training tyre SILKWORMSilkworm 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) 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. FOLDABLE BEADFoldable beads also keep the tire secured to the rim but are lighter weight and easily transported. The bead is made of spun aramid or Kevlar® fibres
