The measurement of Single Transverse-Spin Asymmetries, $A_N$, for variousquarkonium states and Drell-Yan lepton pairs can shed light on the orbitalangular momentum of quarks and gluons, a fundamental ingredient of theproton-spin puzzle. The AFTER@LHC proposal combines a unique kinematic coverageand large luminosities thanks to the Large Hadron Collider beams to deliverprecise measurements, complementary to the knowledge provided by colliderexperiments such as at RHIC. In this paper, we report on sensitivity studiesfor $J/\psi$, $\Upsilon$ and Drell-Yan $A_N$ done using the performance ofLHCb-like or ALICE-like detectors, combined with polarised gaseous hydrogen andhelium-3 targets. In particular, such analyses will provide us with newinsights and knowledge about transverse-momentum-dependent parton distributionfunctions for quarks and gluons and on twist-3 collinear matrix elements in theproton and the neutron.
