How many new bicycles have drum brakes? Vanishingly few.


This was just meant as an example. Bicycles have largely remained in the
stone age, like chuck wagons where a chunk of wood pressed against the
steel ring of the wheels to brake. So bicycles kind of skipped a
technology.

Bikes didn't skip drum brake technology because bikes are primitive.
Only a very few bikes adopted drum brakes because that technology wasn't
optimum for bikes.

It's simplistic at best to pretend what's best for one application is
best for all applications. Every design choice comes with benefits and
detriments, and those are not the same for a 4000 pound car as for a 20
pound bike.

Bicycle rim brakes have worked fine for over 99.999% users for the past
100+ years. When mountain bikes came into fashion, some off-roaders
found a different set of benefits vs. detriments, and discs made sense
for them. But then fashion and marketing took over, pushing discs toward
road bikes.

Yes, we'll get a few testimonials here claiming discs are "better." We
get very few details on benefits vs. detriments.
