Trouble with steep hills

[Eden]

I've never seen a 50/39 combo. Isn't a 50T usually 110BCD?

Somehow I ended up with this weird combo on my rain bike.... I asked for a standard double... I don't honestly get it. So I spin out down steep hills, but don't get any of the advantages of smaller gears???? It hasn't bothered me enough to care to change it, since I'm not exactly mashing out hard core sprints on my commutes or on rainy winter training rides.
