SR made 86 BCD cranks that came in 165mm. The Apex is nicer, the Custom is less fancy. I did manage to find a 165 mm Custom and scrounge up a selection of chainrings. For a while hunting for random bike parts was very entertaining. If I was going to just spend the money and go riding, Merry Sales has a 94 BCD double crankset available in 165mm, and there are still plenty of chainrings around if you want to do something besides 46t-30t.
