Sram Rival 1 x complete groupset for road max Casette

[madu1966]

I currently have a 42 chainring and a 10 42 cassette with a long cage rear derailleur. I would like a lower gear is it possible to fit and run a 10- 50 cassette om this setup?

Not officially. Long cage rear mech has a max sprocket size of 42. But you could fit a smaller chainring
