Your bike has a freewheel instead of a freehub/cassette, so you will have difficulty finding a freewheel with an 11t cog. You can find a generic DNP 11-28t, but I prefer to trust the real Shimano ones over the DNP freewheels. My son's Target Schwinn has a DNP freewheel, and his bike arrived with no grease in the freewheel bearings. I took care of it right away, but still am leery of putting a DNP freewheel on my own bike.
I understand that your bike has a 13-34t already. If you want to get rid of the Megarange 34t cog, you have to switch out the entire freewheel. The Shimano 13-28t freewheel that I mentioned above gives a more useful gear range (in my opinion) than the 13-34t, and it is an easy change. If the Voyager came with a cassette instead of a freewheel, you could simply change individual cogs to suit your needs.
