Yeah, like the others said 46/16 seems like a good ratio for cities (depends I suppose) I ride a 46/16 and I have no issue getting back to moderate speeds from zero.

However, I cannot comment on a "SS scene". I ride a SS (kilo tt pro), but never really encounter much of a scene for it( I mean I see them around, but it's not like I say "yo ss dude, dig the ss." SS just seems like a reasonable way to commute through cities while possessing a bike where maintenance is very manageable.

Go for it!
