X Range
Racing bikes are faster and more powerful than ever before and riders continue to show what bikes with racing bike handlebars are capable of. X-Range™ is the translation for the modern way of riding a racing bike. SRAM has completely redesigned the road bike gearing for more gear range, more comfortable and usable gear grading and, thanks to AXS™, smarter shifting settings. With X-Range™ you are always in the right gear.
