Ahh, lower gearing. OK.
Since you have Sora stuff on there, I'd look into getting a Sora triple Crankset/front derailleur/front shifter (bottom bracket if needed - I'd need to look into BB requirements for the cranks.
It comes with a 30T small ring, 39 middle and 50 big. If you find the 50T big ring useless you could always grind the teeth off and it'll serve as a bash guard.
