24 tooth rear sprocket or 28t front

I’m looking to lower my gearing ratio. I currently ride 22t on the back and 30t on the front.

Going below 30t on the front seems to be entering into a specialist gearyo zone where the fish are £££

A 24t rear sprocket seems to go the other way in that they’re all £ but weigh a tonne.

Any advice? TIA

idk your crankset but i can find 28 teeth raceface cinch for mine

although your current ratio is already 30/ 22 = 1.36 so quite the lowest ! how come you end up going even lower ?
