Dos Piezas TM Dual Stage foams Tear Up the Competition TM by offering incredible side-hill ability, controlled tire-flex with a firm tread-bite that allows lugs to work individually on the toughest terrains.
Stage 1 - The Inner Stage supports the critical part of the tire's carcass, helping beefy crawlers and tall 2.2 tires maintain stability and predictability.
Stage 2 - The Outer Stage provides the deadening effect you need for hardcore climbing, sudden hopping and controlled bumping. Stage 2 also refines many rock crawling tire needs when hitting the big rocks and deep holes. Both stages of foam dampen, as well as react quickly enough for high speed runs seen in crawling and rock racing. No modifications necessary with our Dos Piezas TM...they are ready to go right from the package.
Dos Piezas TM 2-Stage Foams work with popular 2.2 tires, but in particular, when used with our Pit Bull 2.2 Rock Beast (R) Komp Kompound TM tires, our Dos Piezas TM Kompilation TM Foams cause serious Symbiosis. (2 inner and 2 outer per packet)
