  "textContent": "A planar ratchet assembly is provided for a human-powered vehicle, and includes a first ratchet member and a second ratchet member. The first ratchet member includes an axial surface defining a plurality of first serrated teeth having a first driving surface and a first non-driving surface. At least one of the first non-driving surfaces includes a convex curved surface that has a radius of curvature of at least 0.5 mm. The second ratchet member includes an axial surface defining a plurality of second serrated teeth having a second driving surface and a second non-driving surface. The first ratchet member and the second ratchet member rotate together in a driving direction. At least one of the first ratchet member and the second ratchet member moves in an axial direction to permit relative rotation between the first ratchet member and the second ratchet member in a non-driving direction.",
