Upgrading to higher-end rim brake calipers is often touted as a surefire way to improve braking performance, but how much of this improvement is actually due to the caliper itself, and how much is simply a result of the riders newfound confidence in their braking system. Is it possible that the placebo effect is playing a significant role in the perceived improvement, with riders simply feeling more secure and thus riding more aggressively, rather than any actual increase in braking power.
Put another way, if you were to take two identical bikes, with the only difference being the caliper, would the rider of the higher-end bike actually be able to stop significantly shorter than the rider of the lower-end bike, assuming both riders are braking at the same point and with the same level of force. Or would the difference be negligible, and the real benefit of upgrading to higher-end calipers be more of a psychological one.
