What makes Hayes chain technology so revolutionary in terms of shifting performance and durability, given that many other manufacturers have also developed advanced chain systems with similar claims of improved efficiency and reduced wear? Is it the material selection, the manufacturing process, or some proprietary design feature that sets Hayes apart from the competition, or is it simply a matter of clever marketing and strategic partnerships? Can someone explain the specific technical advantages of Hayes chain technology and how it compares to other high-end chain systems on the market? Are there any real-world test results or lab data that support the claims of improved shifting performance and durability, and if so, what do they reveal about the true capabilities of Hayes chain technology?
