Disc brakes are simply better. Take a look around
around automotive and motorcycles. How many new cars
and motorcycles are there that still have drum brakes
in front?

On Sunday I experienced the umpteenth reminder why rim
brakes are inferior. We had to cross some unpaved area
on the road bikes and it had rained. Muddy. Afterwards
a descent on pavement, I reached in and after the usual
and expected one-second of zero brake action the rim
brakes came on. There was an awful grinding noise, you
could literally hear aluminum being eaten.

And yet, you survived. So did your rims.

I've heard that sound thousands of times. I've never had
a crash or rim failure as a result.

Failure in one day, no, I haven't heard that either.Â
Failure over a shorter-than-you'd expect span of months,
I've experienced that personally as have others on this NG.

I've never had a rim fail by that mechanism at all. I'm
not aware of any of my riding friends suffering that failure.

Many, many years ago I was on a mountain bike ride where
such a failure happened to an out-of-town guy I didn't
know; so I understand it's possible. But I don't think
it's at all common, at least around here. And especially
for road bikes.

Someone recently proposed that local soil content can make
a difference. I'm open to that possibility. In our area,
soils typically have high clay content, and I suppose
that's not very abrasive stuff.

I guess we could do a poll. How many here have had a road
bike rim fail by having the brakes eat through it?



I have not and I do not know.

That said, withing a particular area ( mine) the most
frequent worn-out-rim-sidewall riders:

seem to be daily commuter/errand riders on urban streets
with much less mileage than 'enthusiast' weekend riders.
This may well be more an effect of brake use/frequency/style
than abrasive material differences. That's an hypothesis. I
just don't know.
