Sugino XD cranks (XD300 and/or XD600) come in 165mm lengths. Get one,
ditch the inner chainring, and replace the middle and outer chainrings
with whatever size you like. As they use 110mm BC chainrings, you can
go as low as 34 tooth for the second chainring. Either can be found at
Aebike or Harris Cyclery, or probably order from your friendly LBS. I
just converted an ancestor of this crank on a mid-80's bike from being
a 52/42 to a 50/34 for my wife and am very happpy with the result.
