Road bike for my 9 year old son

Giant makes an XXXS road frame with 650 wheels with better components than most bikes marketted for kids.

Actually Giant no longer makes the XXXS. I wish they did, as I sold a few. I sold a felt 24 to a kid last year. Very cool bike. The Blue is also very cool, but I would imagine a bit spendy.
If the cranks are too long I'm wondering if some of the bmx racing cranks could be rigged to work. They have arm lengths down to 110!! I'll have to ask my mechanic tomorrow.
