I'm pretty fresh to the brompton scene if I'm honest, so I'm not familiar with all the mods! I'm assuming the second hand one I grabbed is using the 2 x stock cogs on the rear, so yeah thinking the 54t is the shout for a bigger top end. Do you use the one you linked above or are you rolling with an official Brompton one? Cheers!
