“‘Lock the wheels’ – all brakes will, if applied strongly enough.“
exactly
“Less material at rim = lower mass = less rotating weight = greater acceleration + increased braking efficiency.“
more material in hub and frame to deal with the different forces disc-brakes exert = greater mass = more weight to drag along = slower everything
“Rim brakes rely on very true rims, to be fully efficient. Discs do away with this issue. Dent a rim/snap a spoke on a 100 mile ride, no worries.“
in over 20 years of road riding i’ve had precicely one snapped spoke meaning i merely undid the brakes a bit, this isn’t really an issue
“Makes perfect sense, and youse all know it.“
if it made sense it would already be done, the technology is out there, it just isn’t necessary
you sound like you’ve already made up your mind and are merely being confused by the facts
