Does this sound like a good idea? to run a Sugino Messenger chainring 44t with 19t fixed cog on one side and 15t on the other? I kind of want something that gets me in the 60 gear inch range as well as the high 70s. I run 48x17 right now on my kilo and that seems to fit me well.

also are there more issues with running a small chainring like a 44t compared to running with a 48t?
