Spank have also taken extra steps to ensure that the clamp area of the bar is uniformly cylindrical and as true as possible, improving bar-stem interface which is critical under extreme loads. These can also be used to support bar ends in the relevant disciplines. The Impact Ends reduce the chance of collapse in areas where the wall is thinner and in heavy impacts. Subdued: Live At Roadburn 2017, released 02 December 2017 1. Within the SubRosa crucible, sludgy low-end and high volume lock arms with ultra-melodicism, folk and experimental elements delivered through the haunting ambience of two electric violins. We have optimized the spread of material to counter high stress areas on the bars under extreme-use through FEA (Finite Element Analysis) and rigorous real-world testing. SubRosa SubRosa is an experimental sludge-doom band from Salt Lake City, a city plagued by the tension of opposites. Because the original British editions of Aickmans collections are rare and rather pricey, I first read his work in the slightly-cheaper American collections. Due to the ever increasing demand for wider and lighter bars and more aggressive riding styles, Spank has developed the Dual Extreme Gradual Taper with Impact Ends. Sub Rosa, fortunately, is much more tilted toward the former than the latter, including a number of my favorite Aickman works, and only one real clunker. Dual XGT technology enables extreme precision where bars would otherwise need to be hand-ground, resulting in imperfections and inconsistency in wall thickness. Spank’s new Dual XGT bars are designed using proprietary tooling which is specific to conical diameter, rise and angle - CNC bent on three planes.
