RaceFace engineers meticulously crafted the Era bar over five years, refining it for optimal compliance and stiffness. Dubbed the 'GL tune', it offers Goldilocks-like balance. They discovered that one-size-fits-all doesn't work for handlebars, as cutting them to size increases stiffness. Thus, Era bars come in widths (760mm, 780mm, 800mm) and rises (10mm, 20mm, 40mm) tailored for varied rider needs, with an 8 bend and 5 upsweep.
