I've always had the front brake on the left lever on my road bikes, so have set up my folders all the same. But recently got some wheels from the UK in a box that said in the UK you are required to set up the right lever for the front brake.

As I am setting up my Moulton that comes with the right lever for the front brakes, I'm wondering if I should switch to UK standards or stick to my old ways.
Just wondering how Bromptons standardly come. Are they UK or do the imports have the front brake on the left?
