Challenger Rollers 4.5

The Challenger Rollers feature polycarbonate end caps instead of alloy. They are 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 are available in 4.5 drums.
