The Brompton 2 speed derailleur mechanism is a horrible bodge, and is right in the middle of the road dirt to boot. With a tiny, tiny bearing. I (slightly, it’s not that bad) regret buying a six speed; if I was buying again I’d get a three speed. Weight doesn’t matter very much as long as you remember to alternate arms so that they stay the same length. Unfold and push instead.

Ergon grips are worth it.
