I'm working on designing my commuter (Soma Saga frame--I will post the build progress when I have all the parts), but the crankset has me stumped. I'm looking for a ten-speed triple crank with 48/36/26 teeth and a square-taper interface. JIS or ISO is fine. And I want 175 mm arms, which will probably be the easiest part. Anyone have any suggestions? I'd rather not break the bank with an Alpina 2 crankset, so maybe something under $150.
