Brompton owners

Yeah I think I've seen them, I thought you must have to remove/adjust them.

I tried some amazing garish pink bar ends from the parts bin at a shop the other day, but other than having them vertical, I couldn't get them allow for a neat fold.

I've got Ergon GP3's, they work well on Bromptons and don't affect the fold in any way. There's different sizes, I got the standard/large ones and they fit my S2L fine.
