Challenger Rollers 4.5

The Challenger’s polycarbonate end caps require less material and labor to manufacture and are thus a great lower-cost alternative to our flagship Alloy systems. The ride quality of the Challenger Rollers are every bit as good as the Alloy – providing the same smooth and silent roller experience for which Kreitler is known. Challenger Rollers come with the same Lifetime Warranty against any manufacturing defects or flaws as their Alloy counterparts. Challenger rollers are available in 4.5 drums.
