So, my SuperSix was crushed in a roof-rack accident and last weak my
Roubaix was stolen out of the garage that I left open all night. I've
done that many times -- apparently one too many. I'm down to a gravel
bike and my commuter -- the reborn warranty CAADX (which is a great bike).

The gravel bike is a pig, but I'll use that for fall/winter/spring sport
riding. I want a fast bike, though -- and I've got a line on a nice bike
that I can get with rim brakes or discs, but the disc model will not be
available until December -- which really means that I get to ride it in
dry weather some time around May. I can get a rim brake model by the end of the month.

All the shops are pushing discs, and I did like the discs on the Roubaix
and on my gravel bike. I know this is absolutely the wrong group to ask
because it's wall-to-wall curmudgeons, but if you were buying your last
nice road bike, would you go rim brakes or discs? It will be a dry
weather bike or ridden in the rain only because of bad luck. There would
be no real weight penalty because the bike is so light to start with. I'm
not aero, so I don't care about the aero penalty with discs.

My concern with getting rim brakes is not really even a performance issue
because in dry weather, I've never had a problem with rim brakes -- but
to listen to the guys at the local shop, rim brakes are going the way of
the dodo. I'm worried about buying an antique!

You will be able to get rim brakes and bits for them, I’d though though my
lifetime, I’m currently 42, my dad has managed to get some new tyres for
the NewHudson that they have for rolling along after grandchildren!

As a point of interest - the reason for disks is supposed to be stronger braking. And yet Campagnolo has just gone back from dual pivot back brake to single pivot because too many racers were locking the rear wheel up.

A hydraulic disk has probably five times the stopping power.


There's a subtlety to that.
Front DP calipers offer more braking power where it matters.
Rear SP are plenty strong enough to skid and are lighter, so
DP rear is, in Campagnolo's analysis, unnecessary.

Automobiles have been doing this for some years now. A honking great
set of disks on the front and puny little drums on the rear :-)
