Ergopower was introduced by Campagnolo in 1992. For the 2 prior years, Campagnolo was without an answer to the rising popularity of Shimano's STI. The benefits of being able to shift without removing your hands from your bars were undeniable.
People always talk about how poorly Campagnolo was executing in the late 80's and early 90's. Ergopower helped bring them in to the modern era, and really helped them get out of the funk they were in.
Below is the Italian version of the 1992 Ergopower catalog. I've added the english catalog's text below each of the pages, so those of us who can't read italian can follow along.
Indexed control levers for front and 8-speed rear derailleur, interfaced with the brake levers.
Maximum safety system for total control of the bike without removing the hands from the handlebar.
Ergonomically designed down to the smallest details, with extremely comfortable lever grip.
Total absence of over shift to obtain fast and precise shifting in every gear position.
Possibility to shift down 8 gears in succession in a single movement or to shift up one or two speeds.
Very reduced weight.
Complete freedom of movement due to the internal passage of cables, considerably enhancing appearance as well.

Optimum braking system with incorporated quick release opening system.
Adjusting barrel on frame boss allows fine tuning while riding the bicycle.
Maximum protection of internal mechanism so that operation is unaffected by blows or falls.
Absolute reliability due to the use of high-quality materials developed through new technologies for heat and surface treatments

ERGOPOWER TSC: Total Shifting Control
These revolutionary integrated controls for the braking and derailleur systems provide the ideal ergonomic and functional solution for meeting every individual requirement in any field, athletic or amateur.
Maximum reliability of the ERGOPOWER TSC system is obtained thanks to the perfect symbiosis of the multi-functional transmission systems which Campagnolo has developed thanks to scrupulous technological research.
Ergopower TSC has been designed to work with all Campagnolo 8-speed rear derailleurs, whether for the road or off-road. THe articulated parallelograms of Campagnolo rear derailleurs both with pulleys using adjustable bearings and pulleys using bushings, permit fast precise shifting in every situation. Along with the traditional front derailleurs in Campagnolo's road range, Ergopower TSC can also be used with triple crankset versions.
All Campagnolo cranksets can be used with Ergopower TSC, including the Compact sports version for off-road.
The maximum precision in machining the chainrings ensures perfect engagement with the chain for fast precise derailleur operation.
The new cassette hub for 8 speed freewheel is ideal for sports uses. The appropriately dimensioned axle moving on 4 bearings ensures superior performance in all circumstances.
The 8 sprockets with triple-profile teeth make shifting easy, even under stress, without any margin of error.
All of this is obtained with unequalled lightness thanks to the new Contax chain, the narrowest available today, and to the high precision of the Ergopower TSC control levers.
