Bass players who are into slapping, popping and tapping will love the high end and depth of Lo-Rider. The slight bit of stiffness makes Lo-Rider bass strings very accurate when playing harmonics. Great consistency and great string-to-string balance are DR hallmarks. Lo-Rider provides more depth of tone, and are a bit stiffer than Hi-Beams. Material: Stainless Steel. Hexagonal Core Wire with Ball End. Gauges: 45 ,65, 85, 105, 125.
