Are all rear dropouts the same with?
I wanted to upgrade my 6 speed bike to a nine because one of my friends told me that all rear dropouts are all the same size as long as i change the chain and derrail. Is this true?

your friend is wrong.
6/7-speed spacing was 126mm
8/9/10 speed is 130mm
if your frame is steel you can get away with cramming a 130mm spaced wheel into a 126mm dropouts, but why bother.
just get a new bike.

126mm to 130mm isn't a big difference - that's 2mm outward on each side of the hub! And some old frames are really nice. I'm building up a late 80's Centurion Ironman that I got on eBay. Came with 6-speed freewheel, I'm putting 8-speed on it, stuff that I've had sitting around.
