I'm building up a 1x9 mountain bike to cruise around the neighborhood. I'm using all new Deore components but I don't want to pay $90 for the Deore 3 ring crankset when all I need is the one ring up front. Can anyone tell me where I can find a comparable crankset with only one ring or no rings and I'll get the ring separately? It must be brand new.

Here's what I don't want to have to buy:
