Latin for stronghold and bridge, ARX is our new design for the
perfect connection between fork and handlebar. In particular, we
have optimized the design of the clamps. Steerers and handlebars
are now usually made of composite materials, and 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 even tested this new stem’s
compatibility with other brands of handlebars and it passed with
flying colors. ARX PRO is made of Al 2010 and has stainless-steel
bolts. The material’s grain structure is aligned for optimal
strength, and the weight is a low 150 g.
