Rapidly growing 11 year old.  Already was showing a lot of seatpost on her 26" stumpjumper hardtail aluminum (2008 vintage I think)  At today's mtb race, one of the sponsors backed over the bike with van. Both our fault, no one hurt.  Was wondering if china carbon might be appropriate.  I could build up either a 26 or 29er. Cheapskate dad would want the rear end to be 135qr so I can use on e of my existing wheels.

Any recommendations.  - oh bonus if its pink 

Thx
