hi. i have sram red rear derailleur. i need to swap out the bottom pulley on the rear
derailleur. i see one hex bolt/screw that is holding the pulley in place. is there any
gotcha in swapping this out? should be very easy?

Just like it looks. Just keep track of the little parts when it falls out, so you put them back in right. I don't know Sram specifically, but if it's like the traditional ones, theres the pulley, a bushing, 2 end covers for the bushing, and the screw.

Obviously, remove the chain first, or at least slip it off the chainring to slacken it.
