Latin for stronghold and bridge, ARX is our race-proven design for the perfect connection between fork and handlebar. In particular, we optimized the clamp design. Steerers and handlebars made of composites can easily be compromised by poor clamp design. To assure the integrity of the ARX clamp interface, we perform our own tests that go way beyond the demands of CEN standards. We also tested its compatibility with other brands of handlebars and it passed with flying colors. ARX LTD is the carbon-fiber version of the stem, with Ti bolts. Super-light and super-stiff, it is a highly evolved, modern all-composite design weighing just 114 g.
