Campagnolo Centaur (Q010-MD)

Campagnolo Centaur (Q010-MD) derailleur main image

This is a first generation Campagnolo Centaur from 1989 - with no cable adjuster. The Centaur was launched 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.

This example has the mid-length pulley cage.

Some relevant details are:

  • There is a spring adjuster on the p-pivot.
  • There is no cable adjuster.
  • It has a single parallelogram spring using ~2.0mm wire.
  • The inner parallelogram plate is a steel pressing.
  • The cable is clamped using a hex nut.
  • The pulley wheels are a conventional ball-bearingless design in white.
  • The inner pulley cage plate is steel and has a spoke deflector.
