Is the sense of connection riders feel with rim brakes during a ride merely a placebo effect, or is there a tangible, mechanically-driven explanation for the perceived difference in control and modulation compared to disc brakes? Some argue that the direct, linear feel of rim brakes allows for more intuitive modulation, while others claim that this is simply a result of rider bias and habituation. Can the differences in brake pad-to-rim interface, caliper design, and cable/hydraulic actuation truly account for the distinct sensations reported by riders, or is this a case of the brain playing tricks on the body? What role do factors like lever ergonomics, brake pad compound, and wheel design play in shaping this sense of connection, and how might these variables be optimized to create a more immersive riding experience?
