Does anyone know if Mongoose changed the design of the rear dropouts on the rear triangle of the Mongoose Teocali between 2005 and 2006. I have a 2005, but just recieved a 2006 replacement rear triangle. Now my old derailleur hanger doesn't fit on the new triangle that didn't come with a hanger.

looking at the mongoose web site & comparing the '05-'06-'07 years the change occurred after '05 as well as the cable stop locations.

I ordered a derailleur hanger for an '07 teocali from derailleurhanger.com and it fit the '06 traingle I recieved. FYI.
