Seems most bikes either come with 50/36 rings and an 11/32 or 52/39 rings with an 11/28 cassette. I live in hilly terrain and do need lower gears but often feel spun out with my 50/36 by 11/32, could you run a 52/39 with an 11/32?
Yes, you can, although you'll need a longer chain to go with it.
The important thing here is the capacity of the rear mech you're using. However, since your bike already has 50/36 11-32 gearing, changing the chainset for a 52/39 actually reduces the amount of chain slack the rear mech has to deal with (52-39 < 50-36), so there shouldn't be any problem.
Just remember to adjust the position of the front mech (move it up the seat tube) to accommodate the larger chainrings.
