Specs on components may vary; confirm before ordering
Dropper post not recommended for most kids this age due to complexity and safety concerns

Minimum seat height (24.4") is about 1.5" higher than competitors; can be lowered by cutting seat post
Higher bottom bracket and longer crank arms (127mm) may make efficient pedaling harder for shortest riders
