Mountain bike brakes developed by Campagnolo in the late '80s/early
'90s. When mountain bikes started to get big in the early '80s
Campagnolo dismissed them as a short lived fad. When it looked like MTBs
would be here a while they brought out a series of MTB component groups
that had some interesting ideas that did not sell well. At one point one
member of the Campagnolo family was traveling the US MTB racing circuit
talking to racers and (I think) entering races, trying to find out what
would work and what wouldn't. They finally decided to stick to road bikes.

The brakes in the photo look like the "mono-planar" design, one of the
brake arms passed through a slot in the other arm.

As mark mentioned and the brakes are 'u-brakes'. Made obsolete by
cantilever brakes..different post placement.

Made obsolete? I mean, Cantilevers were around for decades before U-
brakes (and other high-post brakes, like rollercams). It's more like
the fad passed than they were made obsolete.

Maybe they were made obsolete by _low-profile_ cantis, which addressed
the heel clearance issues high-post brakes supposedly addressed.

Circa 1990 MTB brake set. A bit heavy but very well made. Levers have
more position adjustments than other styles.

Note that few frames have "U Brake" brazed bosses above the rim ( higher
than cantilever/V bosses)

U brakes collected dirt and mud behind the rear wheel so MTBs,
originally using u brakes, went to cantis. Center pull brakes were
around for decades and u brakes werte just a modification of those.
Cantis were a fairly recent developement in the 80s.

"recent"??? I beg to differ.

The touring bikes we sold had cantis from our first days (1971) and were
a common wide-clearance or ultralight solution for twenty years before
that (Gitane Hosteler up through Bob Jackson Lugano as well as tandems).

Mountain bikes went canti as soon as the 890/1000 sidepulls proved
inadequate - and that was several years before most people knew what a
'mountain bike' was.

Tom Ritchey's USA 'Commando' and Mike Sinyard's Japanese 'StumpJumper',
among the very first popular models around 1980, had Mafac cantilevers
exclusively.

As volume grew, designers added "U-Brake" bosses at the chainstay, being
concerned with seatstay flex. The downside problems appeared promptly
(dirt, as Peter notes - and there are many others!) and they disappeared
a few years later.

As another writer noted, Valentino Campagnolo took a lively interest in
American mountain bikes at the very moment when bike designers were
obsessing over seatstay flex so their Record OR, Olympus, Euclid series
included U-Brakes. That was quite au courant. Really!

Campagnolo also offered cantilever models with all MTB series. Lever
pull is the same but the frame bosses are not.
