This video reviews the new Specialized S-Works Power Evo saddle, comparing it to the original Specialized Power saddle and the Selle Italia SLR Boost S3. The presenter, James, who previously disliked the original Power saddle for being too wide, tests the new Evo model using pressure mapping and by feel to determine if the design changes have improved comfort and performance. He also discusses common saddle issues and the importance of proper bike fitting.
