Can you clarify what '
the seat tube is much lower than the front end' means?
Both frames have similar BB drop and are within a couple mm of on each other.
Do you just mean that the niner' top tube slopes more?
They are very different costs and different material.
To compare like material, there is a Carbon Renegade frameset too...
