Don't know if anyone's tried this: My wife has a XS (14") mtb but she still has no standover clearance (yes, she is tiny). So I originally considered a 24" wheel bike, but they never come with any decent forks. What I am thinking of now is to get 24" wheels and put them on the frame, it has disc brakes so diameter wise there should be no problem. If there is a differenc in hub length I could probably lace a 24" rim onto a standard hub ? Has anyone done something like this before ?
