Help with SRAM compatible shorter cranks

[flmcanuk25]

Hi,
I'm quite new to all this and a bit overwhelmed when researching some options for my TT bike.
I have an Argon-18 E117, which has SRAM Rival AXS 2x. I have this specific crankset https://www.cjperformancecycles.com/components/gears-drivetrain/sram-rival-axs-d1-dub-crankset-in-black__142526?currency=GBP&chosenAttribute=CW8614006

I want to go down to 150-155mm cranks. SRAM only offers these in Red/Force and I can't simply swap out my cranks even if I did buy them because, as you can see, the cranks are integrated into the chainring.
I have a SRAM DUB PF 86.5 BB.

Which leaves me with the only option being changing out the whole front chainring setup as far as I can tell. 

I'm not especially fussed about weight, more so value and simplicity.
Any specific recs on a setup I should be looking for?

Hi.
Well you need an AXS 2x crankset with dub (29mm) spindle to match your BB, and 150/155mm crank lenght.
There are limited options specially with those cranks lenghts, but here is one:

And another a little more expensive:

https://es.aliexpress.com/item/1005009424830295.html?spm=a2g0o.productlist.main.39.1d60osLzosLz2w&algo_pvid=6df2a8ab-7235-4de7-8940-5c3f9b0e98c3&algo_exp_id=6df2a8ab-7235-4de7-8940-5c3f9b0e98c3-36&pdp_ext_f=%7B%22order%22%3A%2241%22%2C%22eval%22%3A%221%22%2C%22fromPage%22%3A%22search%22%7D&pdp_npi=6%40dis%21USD%21528.84%21280.29%21%21%21528.84%21280.29%21%402101de2517856839605701546e0d56%2112000052605389212%21sea%21AR%21185111422%21X%211%210%21n_tag%3A-29919%3Bd%3A9ba602fd%3Bm03_new_user%3A-29895&curPageLogUid=Q8atvSIm0saj&utparam-url=scene%3Asearch%7Cquery_from%3A%7Cx_object_id%3A1005009424830295%7C_p_origin_prod%3A

Or you can buy the dub 150/155mm crankset, like this one:

And then buy the Red 2x chainrings:

Or if you want to go all Aliexpress way, you would need to buy the cranks, the chainrings and then an 8bolt adapter to the chairings. But I think it´s not cheaper, not better and needs more work and investigation.

Hope this helps
