Unless you're doing some brutally steep climbs, you won't be using the inner ring (or you'll be way OTB).

However the inner chainring will only be about a 100 gram weight penalty.

You'll be fine racing what you got. If you get into racing, stay with it, and move up, you might consider some gearing changes, but you really don't need to.

And if you happen to be one of the gentic freaks that goes from Cat 5 to Cat 2 in a season, you can really have fun upseting some people riding your triple.
