2026 Transition Spur vs 2025 Giant Stance

The XL is the Giant Stance size closest to your L Transition Spur. 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 Stance

Compared with the Transition Spur in L, the Giant Stance in XL places the top of the head tube 6 mm higher and 20 mm further forward, relative to the bottom bracket. Its wheelbase is 29 mm longer, which can contribute to stability at speed.
