Aurora
Blending the responsiveness of our Reactor road race frame with the versatile handling and confidence of the Great Divide, the Aurora is our range-topping model for all occasions.
A top priority when developing the Aurora was to balance high stiffness and crisp handling with all-day comfort levels that only titanium can deliver. Despite an overall stiffness level approaching our race-specific Reactor model, the Aurora is the smoothest riding frame we offer. A combination of carefully shaped and butted tubing, svelte seat stays and the one-piece carbon seat mast result in a frame that smooths vibration like nothing else on the road.
