Needing/wanting a new crankset... what do I need to be paying attention to? (Xposted)
I've been toying with the idea of changing to a 1x10/1x11 setup. But the narrow wide chainrings on the market won't fit my Campy Victory's (obsolete) 116 BCD crank.
I assume the solution is to change to a crankset with a more conventional BCD (104, 110, 130?).
According to VeloBase, the Campy Victory BB is ISO.
Am I right to think that I just need to make sure the crankset I get fits ISO?
Is there anything else I should be taking into consideration?

Another ISO capable crankset might work. But really, you should probably get a new bottom bracket for whichever crankset you purchase as there's a good chance the spindle length required for the new crankset won't be the same as your old one, giving you poor chainline. Whenver I get a new crankset, I always get a new bottom bracket to match. Most BB's are cheap enough that it's just not worth taking a gamble on whether or not your new crankset will fit it.

Save yourself the headache and buy a crankset and the proper length bottom bracket. Trying to guess what the new chain line will be more than likely, will require a few bottom brackets to test fit any way. Keep in mind that with a 110 bdc crank the smallest ring you can run is 34th. You may also want to look for a chainring that has special teeth to help prevent dropping the chain if you thinking of riding the bike over rough terrain.

That would be the reason to do any of this. The suggestion I'm getting is that I might not even need to change it if I'm not going to be bouncing around much. I guess the question in that case is "what counts as rough terrain?"

Well, I'd think of rough terrain being anything that's going to bounce you around a lot. So a dirt path might not be rough if it's reasonably smooth, but if there are a bunch of roots or similar, it'd be rough. And I've certainly ridden paved roads around here that I'd classify as "rough" because the potholes are bad enough to really hit hard if you go right over them.
Not sure, but if your RD cage spring is strong enough to keep the chain under good tension, you may not need to worry too much.
