2023 Canyon Neuron vs 2025 Giant Fathom

The S is the Giant Fathom size closest to your XS Canyon Neuron. We match frame stack and reach. This is a geometry comparison, not a fit recommendation; stem, spacers, handlebars and saddle setup also affect your riding position.

What changes on the Giant Fathom

Compared with the Canyon Neuron in XS, the Giant Fathom in S places the top of the head tube 35 mm higher and 15 mm further forward, relative to the bottom bracket. Its wheelbase is 18 mm longer, which can contribute to stability at speed.
