Inventive embodiments are directed to components, subassemblies, systems, and/or methods for continuously variable transmissions (CVT). In one embodiment, a main axle is adapted to receive a carrier assembly to facilitate the support of components in a CVT. In another embodiment, a carrier includes a stator support member and a stator interfacial member. In some embodiments, the stator interfacial member is configured to interact with planet subassemblies of a CVT. Various inventive planet subassemblies and idler assemblies can be used to facilitate shifting the ratio of a CVT. In some embodiments, the planet subassemblies include legs configured to have a sliding interface with a carrier assembly. Embodiments of a hub shell, a hub cover are adapted to house components of a CVT and, in some embodiments, to cooperate with other components of the CVT to support operation and/or functionality of the CVT. Among other things, shift control interfaces and braking features for a CVT are disclosed.
