There is no chrome on this one, but otherwise it is indistinguishable from the original. It says Shimano. I appreciated that the cage could be opened to allow the chain to be inserted without opening a link. It went on with only a very small adjustment for the small sprocket overtravel. There is no documentation, so if you're inexperienced with this repair be sure to take a picture or two of the original installation before beginning. You'll need a decent set of metric Allen wrenches. It's easiest to set up if you set the shifter to the 4th gear and then place the chain on the 4th sprocket before tightening the cable clamp on the Derailleur. For the price this is a fine solution for a casual use bike.
