Anyone have the SUGINO OX901D Compact Plus Crankset?
I'm thinking about getting the 46/30T version with 172.5mm crank arms. Link
What concerns me is that the Q-factor is slightly narrower than my current Ultegra crank, and those crank arms are already very close to the chain stays (i.e., within 5mm). If the thickness of the crank arms is the same as on my Ultegra crank, I think I will be ok, but if they are thicker, I may have a problem.
If you have one, could you check the distance from the inside surface of the outermost tip of each crank arm to the center-line, or if that is too much of a hassle, just let me know how thick the crank arm is at the extremity.
Any other advice you might have is more than welcome.
(One workaround would be to get a shorter crank arm, but I don't want to lose the leverage and change the fit on the bike.)

My current crank arms come with 5mm of the chain stays. If the new ones are too close, is it possible to put spacers on to push them out a bit (like these)?

I have the OX601D. I'm not sure if it's similar in construction to the OX901D, so this might not help.
Crankarm width at end (measured at edge of pedal hole closest to end of arm)
DS = 0.550"
NDS = 0.556"
Past the pedal hole the end of the arm tapers slightly away from the bike, but it's not uniform (hand ground?) and hard to measure repeatably. The taper adds 1-2mm of clearance at most.
Total width, outside to outside = 5.562" (assembled off bike, no BB)
Distance from centerline to inside of crank arm end (assuming symmetry)
DS = 2.231"
NDS = 2.225"
I hope this is what you were looking for.

I suspect if you put spacers under the BB cups, the NDS crankarm wouldn't be able to engage the full width of the spindle splines. It might work, but it's probably not officially recommended.
