Brompton Speed Change
I have a standard 2s Brompton from 2018 (I think?) but the gearing should be 54T x 12/16. It's been fine but I think I'd like to make it a little speedier. Generally what are the pro/cons of switching out the chainring vs replacing both cogs? I think the ratio between the two is about right but I just want a slightly faster gear than 12 and 16.

There are third party cogs with 11t for the Brompton.
There is also a 3 speed conversion with 11-14-17t https://www.bikegang.co.uk/bikegangh...-9S-p194768178
