Yes it is a MAG brace (a 20/30).
The frame, if it does for some unknown reason get to the binning stage, keep the hanger (or i'll have it) as it fits many frame including the orange Alu-O as it looks to be the standard A-Pro one.
Sorry, I meant the seatpost (15) and saddle (17). I wrote stem as I'd been looking at them on another thread!
