Affinity Jarrod Bruns Signature Bars. This is Jarrod Brunâs signature colorway. The color is Transparent Blue and it screams style. Jarrod chose the trans blue color because it adds color while still being able to see the craftsmanship that goes into creating these handlebars.The XL T bar is constructed from American sourced 4130 Chromoly, the same stuff used in NHRA Race Car Roll cages and BMX bike frames. The material is processed by hand and is carefully inspected upon each process. They are TIG welded by John Radtke & Chris Gascoigne then powder coated to protect the metal and showcase the work.
