And it was no more than two or three years ago when I posted that disc brakes would take over the market because they were a superior brake. At that time I took a lot of abuse for my prediction.
There remains two overridding reasons that discs are superior. Better stopping power in the wet, and they dont ruin high priced rims.
Disc brakes in the beginning suffered the old foggyism that seems to run rampant in the cycling community. I remember very well how the "real cyclist" resisted click shifting, and clipless pedals.
