Name that part
 

Hey,
Trying to figure out what derailleur I have on my bike. This is on a Bianchi Sport. Sorry for the small photo, its to dark to take a new picture at the moment. It is a Shimano, but any idea what series?http://img.photobucket.com/albums/v2..._DSC1308-1.jpg

probably light action

Like this one with no logo.

That looks to be it. Thank you junkfoodjunkie!

Yep, shimano light action. The logo was rubbing off on mine so I just finished the job and removed the rest:

Shimano Light Action.

Another vote for Light Action. A couple of variants were produced; one with an engraved logo, the other silkscreened.

The silkscreening often comes off the latter variant - I Dobbinized one once. Very easy to polish up.

Yep, light action. And it probably works pretty good, doesn't it?

It does in fact work very smoothly.

They do work smooth, though the overshift spring slows down the response time a bit too much for my liking.
