  1. Abstract Suppose that $$X$$ is a smooth projective variety and that $$C$$ is a general member of a family of free rational curves on $$X$$. We prove several statements showing that the Harder–Narasimhan filtration of $$T_{X}|_{C}$$ is approximately the same as the restriction of the Harder–Narasimhan filtration of $$T_{X}$$ with respect to the class of $$C$$. When $$X$$ is a Fano variety, we prove that the set of all restricted tangent bundles for general free rational curves is controlled by a finite set of data. We then apply our work to analyze Peyre’s “freeness” formulation of Manin’s Conjecture in the setting of rational curves.
