I have triples with a 130/74 spider on all of my and my wife's bikes. Not one of them still has the 30 tooth inner ring still on it, they all have a 26 (tourers and commuters) or 28 (racers) tooth inner ring instead. They also all have some sort of chain retention device. If anyone needs a 30 tooth ring, I have a stack of about five barely-used ones!

The big advantage I find with this setup is that you can still have a really small lowest gear with a cassette that goes up to 25 or 26 teeth, but you don't have the big jumps between lower gears that you do with a cassette that goes up to 27 or 28 teeth.

BTW, the smallest ring you can get on the 74mm BCD is a 24 tooth, but I've never needed to try one of those. If you want that, then you should get yourself a crankset with a 110/74 spider, or a MTB crankset, so that the middle ring can be a bit smaller.
