based on what ive seen with some of the kids (well they are like 13-16yo) in the clubs aroud here they all started with mtbs or they had small road frames with 650c wheels...i know that pinarello makes kids road bikes but it seems like a very costly especially for a kid who will outgrow it quickly...but here a link to them anyways http://www.pinarello.com/main.php?su...%2Fkids&lang=e
one thing to make sure it to not over train because it can have lasting affects on a childs growth...
