The Brompton 6 speed tensioner can cope with slightly bigger rear sprockets than the 3:
is this due to smaller jockey wheels or because the inner tensioner arm is longer on down direction?

Re: Brompton tensioners 3vs6?
Is this any help ?
My rusty, sorry, trusty steel rule shows the 3 speed derailleur inner tensioner arm is 64mm long while the 6 speed is 69mm (ish).

Agitate, educate, organise.

Maybe it's because it needs to cope with both the fold and the difference between sprocket sizes.
