Both are 5 arm chaining spiders, and the one you have recieved will be a lot easier to work with than the one from the orginal picure, as the bolts for the chain rings are all easily accessable the one in the auction, has a 5th arm, this is hidden behind the crankarm.
I have a feeling that the picture is a stock photo of a older verion of this item, not the current production item, also, it does note that it is silver in the photo.
At the end of the day, you have got the right / current product, the image in the auction was incorrect, but if you look at the manufactures image, this is what you got.
It does not matter if it is up to Sugino quality, as it is not a Sugino chainset, as I orginally said if you wanted one go an buy one, don't buy Stronglight, then complain as it wasn't a Sugino like you thought it would be.
