2027 Canyon Neuron vs 2025 Giant Fathom 29

The XL is the Giant Fathom 29 size closest to your L 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 29

Compared with the Canyon Neuron in L, the Giant Fathom 29 in XL places the top of the head tube at about the same height and 10 mm further forward, relative to the bottom bracket. Its wheelbase is 4 mm shorter, which can contribute to quicker direction changes.
