The ratcheting action on the Suntour Barcons is the old style "Power Shifter" style, the newer Silver/DiaCompe shifters is based on the new and improved ratcheting action that started with the Sprint shifters around 1985. It's smoother with finer ratcheting.

Simplex Retrofriction shifters are a whole 'nuther deal- they don't ratchet- it's a spring loaded clutch system.
