2023 Specialized Demo Race vs 2025 Forbidden Supernought
The S1 is the Forbidden Supernought size closest to your S2 Specialized Demo Race. 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 Forbidden Supernought
Compared with the Specialized Demo Race in S2, the Forbidden Supernought in S1 places the top of the head tube at about the same height and 6 mm further back, relative to the bottom bracket. Its wheelbase is 27 mm shorter, which can contribute to quicker direction changes.
