E-Grifn – Shimano Ultegra DI2 2x12sp

Gravel
E-Grifn – Shimano Ultegra DI2 2x12sp is a carbon electric gravel road bike (2024), by Ridley. This model is best for riders looking for a balanced setup, leaning toward a balanced riding position, with a surface profile that is ready for gravel routes as well as pavement. The main strengths in the metrics are strong speed potential on smoother terrain, a balanced ride feel between comfort and directness, and less emphasis on aero shaping than on comfort or versatility. That said, compared with more specialized alternatives, the compromise is more of a flat-to-rolling terrain bias than a climbing focus and a value score that depends more on priorities than pure price efficiency.
