It's been quite a controversy for pros. More than half don't care. Some sorry about the danger of the disc cutting riders in a crash. Some feel it hurst aero wise. Many don't see the need unless it's a mountainess course with lots of long steep descents. The majority see advantages in wet conditions. Many only want them in races where everybody has them or no one.
So if a recreational rider doesn't ride steep descents and doesn't ride often in the rain, why get them?
