A continuously variable transmissions (CVT), includes a main axle adapted to receive a shift rod that cooperates with a shift rod nut to actuate a ratio change in a CVT. An axial force generating mechanism can include a torsion spring, a traction ring adapted to receive the torsion spring, and a roller cage retainer configured to cooperate with the traction ring to house the torsion spring. Power roller-leg assemblies can be used to facilitate shifting the ratio of a CVT. A hub shell and 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.
