The Addict Johann Moreau Shredder Bar was designed with specific input from Addict Team riders Jean-Yves Randriambelson, Matt McKeen, Alex Peasley and Johann Moreau. Addict wanted something strong while maintaining the elasticity of steel, so the Addict Shedder bars are made of Chromoly 4130 and fully heat-treated after welding to add more strength. The horizontal tube is butted externally while the top tube is butted internally. Butting allows the tubes to be thick where it needs to be (at the ends, for welding), and allows the bar to be thinner and lighter where it can be, in the center, for example.The Johann Moreau Addict Shredder Signature Bar has gussets, which are half tubes which protect your hand from bad landing while doing barspins. The Johann Moreau Addict Shredder Signature Bar has a backsweep which is 3 degrees. All in all a great bar at a awesome price.
