I'm setting up a new Brompton, Titanium version. I'd like to have it lightweight, so I'm leaving out the mudguards and rack, which will save me about 700 grams. I hope to also have a better handling when swinging the back wheel, I always have felt it to be a drag with those parts, with my past Bromptons.

However, for the occasion of bad weather or the necessity of transport, I'd like to have an option for these components.
1.) Does anyone know any clip-on mudguards that work well for the Brompton?
2.) What lighter racks can you recommend over the standard version (about 300 grams I think)?
