It seems everything I look at is for triples. Is this likely to be a problem?
Pffff.
Absolutely no drama. As Jeff Wills says, it just means there'll be unused shifting aids.
Although it does mean slightly less metal in some of the teeth, which by rights would lead to shorter life.
So you'd be paying a bit extra for fancy bits that won't be used and it won't last quite as long as a plain one.
