are these genuine SRAM chainrings?

They rather look like it. But if the shifting is good, they're probably fakes - that vintage genuine SRAM rings are notoriously flexy, resulting in rough shifting.

do you have a recommendation Duck? these are for my TT bike, so I'm not too fussed about shifting as I don't do a lot of it in TTs.

but they're also for a Quarq which a mate is trying to convince me I should swap between my roadie and TT bike, so shifting would matter then!

I assume you mean that newer SRAM rings would shift better?

2013-onward rings are considerably stiffer, which means much better shifting plus easier front derailleur tuning, because the damn things aren't trying to run away when you push the chain against the big one.

They look the same as what I just bought from Bike24, albeit I got a 53/39 & 46/38 139BCD set.
Unlike the rubbish that came with my SRAM Cranks in 2011, these ones seem ok so far.

these are S1 (series 1) rings, which I'm assuming are the old, flexy ones. I might have to grab these, as the price for series 2 onwards goes skywards.
