I want to swap out the chainrings (double) on my daughter's Cannondale bike and put on 50-34 rings. I can't find a place to buy Truvativ Roleur rings in this size to match the current crankset on her bike. Are Shimano or other manufacturer's rings compatible?

depends on the bolt circle diameter
I have used standard (53/39) shimano rings on truvativ Roleur cranks and they work fine. I would guess, however, that 52/38 is about as small as you will find for 130 BCD cranks.
