A benchmark in cost-effective performance, the Aura has the latest tech in aluminum frame construction. Retaining the stiffness-to-weight ratio that distinguished the original Helium, the Aura SLA uses exceptionally thin-walled tubing sections with double-pass welding on the head and seat tubes for a frame that's both tough and light. Worried about the bone-shattering stiffness that used to characterize aluminum? Don't be. Thin, strong seat stays, a svelte seatpost and the beautiful carbon fibre fork keep it comfortable and responsive, like carbon bikes twice its price. A sweet sprinkling of Shimano and 4ZA components makes this ride a special one. A Shimano Tiagra groupset creates a classy build, while 4ZA RC30 wheels provide everyday performance.
