I'm converting an old Austro Daimler Vent Noir into a rando bike. That means, sadly, I have to replace the beautiful, drilled-out black first-gen Dura Ace crankset, because it has 53-42 gearing, which is way too high.

I'm looking at either getting a VO or SunXCD 50.4 BCD crankset (I can get the VO for a lot cheaper) with 46/30 rings, or just putting on a new Sugino triple. I already have the Sugino on my touring bike, and it's great, but I wouldn't mind trying something new. Also considering the new external BB 46/30 cranksets from FSA and Easton, but I wonder how that'd look/feel on a vintage bike.

Anyone have experience with these 46/30 cranksets? Any recommendations generally?
