Wise Words:

Mechanical disc brakes are:
a: A little heavier
b: No better than good V brakes (but a little better than cantilevers, and
significantly better than dual pivot calipers).
c: More prone to damage (oh look, I've just bent the rotor)
d: Attract theft
e: More expensive

Do we assume that by 'mechanical' you mean cable-operated? Hydraulic
ones offer many advantages.

oops... was not intended to go back to urc!! Thanks to Mr Raven though
for helping my mate understand why he should spend his money on other
things.

I'm in mid-process of trying to persuade a friend of mine to NOT buy a
BSO, hopefully he will end up with something that will actually be fit
for purpose (although I'm not sure he's quite defined his "purpose"
properly yet).

Apologies for bothering the group.

You forgot to mention the advantages of disc brakes, including cable
operated.

a: They won't be affected by a bent wheel. It's far easier to bend a
wheel than a rotor.
b: Even if you do bend a rotor, it can just be bent back.
c: They will still work even when covered in mud and water.
d: Being further from the ground the braking surface is less likely to
get covered in mud/water anyway.
e: Easier to maintain.

Hope this helps ;-)

Oi!

ah. that'll be another apology then... sorry Mark. Still, wise words
nevertheless - ta very much!

Some advantages: chiefly, better feel and better modulation. Still suffer
from problems a, c, d and e. And yes, I have - and regularly use -
hydraulic disks, V brakes and dual pivot calipers.

Oh yes, I quite agree, although d is really a UK problem that's
thankfully behind me. Not sure about c, either, but I've only been
using mine for a short while, so I'll bow to your experience.

AOL. I do like the feel of the disks though (Juicy threes, if it makes
a difference). Certainly seem much more pressure sensitive (I guess
that's what you mean be 'modulation'😉. Point e, thankfully, is also
one I no longer need to worry too much about.

On planet Zog, perhaps. On earth, impossible to bend to within the
tolerances required.

Not impossible but maybe difficult. When I was working in an
engineering factory in my student summer vacation one of the apprentices
was set the task of flattening a sheet of steel. After a week of
hammering it was no flatter with every lump hammered down leading to
another appearing elsewhere. After he had been doing it long enough to
teach him the difficulty one of the old hands drew three chalk circles
on the sheet, told the apprentice to heat each to a dull red heat and
let it cool. As it cooled the whole sheet pulled flat. A memorable
demonstration of experience over brute force.
