  We study supersymmetric AdS$_2\times Y_9$ solutions of 11d supergravity where
$Y_9$ is an $S^7$ fibration over a Riemann surface equipped with a metric of
non-constant curvature. We consider two classes of Riemann surface: the first
is a spindle and the second is a topological disc. These solutions are
interpreted as the near-horizon limit of M2 branes wrapped on the Riemann
surface and describe the near-horizon of a 4d black hole. In the case of the
topological disc there are additional flavour M2 branes smeared on a
five-sphere embedded in the transverse $S^7$. We perform a full global analysis
of both classes of solutions, both from a 4d and an 11d viewpoint. Finally we
compute the two-dimensional Newton's constant from which we obtain a prediction
for the entropy of the black hole.
