Ofmega Linea (1st style)

Ofmega derailleur main image

After Ofmega's distinguished history producing distinctive, and distinctively odd, derailleurs, this is a sorry-assed item - a Simplex off-the peg design, simply rebranded.

Sure it’s a slant parallelogram design, sure it’s all metal, sure it’s perfectly serviceable, but all the style and pride that Ofmega expressed in their earlier designs is long gone. The castings are slightly imprecise and have a light case of acne. On the steel pulley cage plates the styling is a touch clumsy, the edges are a bit rough, the chrome is inconsistent, sometimes silky and smooth, sometimes thin, rough and wrinkly. And, at times, the branding looks like badly applied Letraset.

In its Simplex guise this derailleur was called the ‘Vallée’. Ofmega called it the ‘Linea’. I was told that this design was supposed to compete, head-to-head with Shimano's Ultegra. Some chance. ‘Vallée’? ‘Linea’? I call it ‘commercial suicide by laziness’.

I think that this is an early version of an Ofmega Linea. I think the Linea was launched with a choice of one of two finishes - this 'all polished' look or a painted two-tone grey finish. Its main features are:

  • The word 'Ofmega' on the outer parallelogram plate, and nothing else.
  • An all polished finish, with chromed steel parts.
  • A hex cable clamp bolt.
  • Hex pulley bolts.
  • The tab that engages with the gear hanger is at 11 o'clock on the b-pivot.
  • The pulley cage stop allows the cage to rotate around behind the parallelogram.
  • The cable is routed around a simple round pillar in typical Simplex 6-speed style.
  • One of the parallelogram pivot pins is removable and has a Posidriv head.
