I need some recommendations for upgrading from an FX4 to a drop bar for my 13-year-old daughter. The FX4 is a carbon and speed-focused flat bar fitness bike, She's looking towards making some gains and learning to ride a drop bar with the new bike.

I was looking at some aluminum-framed Liv bikes which appear suitable for safely leaning drop bars but I am not convinced the weight and groupsets will allow the gains.
