ARX is 3Ts design for the perfect connection between fork and handle bar. In particular, 3T optimized the design of the clamps. Steerers and handle bars are now often made of composite materials, and can easily be compromised by poor clamp design. To assure the integrity of the ARX clamp interface, 3T performed tests that go way beyond the demands of CEN standards. ARX PRO is made of Al 2010, has 4 stainless-steel bolts and an angle of ± 17°. The materials structure is aligned for optimal strength.
