I bought these cranks for other features (165mm, BB30, sufficient material for tapping additional pedal holes, low Q). The only other crankset I'm aware of that meets those criteria is the FSA Omega BB30. Rival 22, Cannondale SI, FSA Gossamer don't appear to have enough material for shortening. The S350-1 crankset would be perfect for my application if it can in 165 or 180+, but it doesn't.
Apex 1 cranks arrived. The bolt pattern is 110bcd. It is not symmetric about a line drawn through the BB and the pedal spindle axes. The closest hole (clockwise from the right side of the bike) to the crankarm is 60 degrees away. The next is 360/5=72 degrees from that (same hole-to-hole distance as symmetric 5-bolt cranks. The next is 108 degrees from that. Then 72 degrees again.That makes the other hole 48 degrees from the crankarm.
I don't have any Shimano 11-speed rings for comparison. This pattern is definitely not compatible with FSA 110bcd ABS or Campy 112bcd 4-bolt. A chainring with 10 evenly spaced holes at 110bcd would fit (Rotor, perhaps).
