2013 Argon 18 Radon Frameset

For the R&D team at Argon 18, pursuing our ultimate goal of OPTIMAL BALANCE is an ongoing concern:  we're on a mission, trying to create the elusive dream bike, as perfect as possible in every way.  Because OPTIMAL BALANCE defines an optimal mix of qualities rather than a specific material, its principles are applicable to metals as well as carbon composites. 
With the 2013 Radon, we've arrived at the perfect combination of aluminum and carbon.  The lessons learned in developing the Gallium Pro and other, earlier bikes have been incorporated into this high-performance, high-quality frameset.  A carefully designed ultra-light triple-butted aluminum main triangle complemented by a carbon fork and rear triangle has made the Radon a benchmark in its market segment.  This kind of performance and value combined make the Radon the exception rather than the norm.
