Campagnolo Centaur (Q010-SM)

Campagnolo Centaur (Q010-SM) derailleur main image

The Centaur was launched in 1989 as a lower cost alternative to the 1988 Campagnolo Euclid. As far as I can tell the only difference was that the inner parallelogram plate was a steel pressing - which was presumably marginally cheaper than the Euclids aluminium forging.


I believe that this is a second generation Campagnolo Centaur from 1990 - with a cable adjuster.

Some relevant details are:

  • There is a spring adjuster on the p-pivot.
  • The cable adjuster is round and threads straight into the aluminium of the b-pivot.
  • It has a single parallelogram spring using ~2.0mm wire.
  • The inner parallelogram plate is a steel pressing.
  • The cable clamp nut is a smooth Allen key item.
  • The pulley wheels are a conventional ball-bearingless design in black.
  • The inner pulley cage plate is steel and has a spoke deflector.
