Just be aware that the 14 tooth front sprocket will eat your chain quickly.
While the bike shop where I purchased my 14t sprocket was happy to sell it, they also acknowledged that premature chain failure is a common result when I came back in and ordered a 16/44 setup. Kind of expensive, but I shouldn't have to buy another chain for a looooong time!
I'm curious to know how long you expect a chain to last. I put about 12,000 miles on my first chain and only changed it because it had developed a couple tight spots due to me not cleaning/lubing it enough and the first mod I did on my bike was the 14T front sprocket.
