I got my gears yesturday and they look like steel but are really not. I put a magnet on them and it did not stick. They definatly are not aluminum either. They do have the same color of my ti skids which makes me think these are true titanium gears or chromoly which is also good. I didnt notice before I couldnt use them with my single speed set up so I am not sure I am going to use them so I might resale them.
Notice the idlers are exacly like the UE idler on the top left except alot lighter.
