kool stop brake pads?
 

Or something else? I need to replace my worn rear pads with something suitable for the rather damp London conditions. I'm a bit confused by the Kool Stop range, haven't got my head around all the permutations yet.

salmon is good in wet conditions. they also make your rims last a bit longer because they use a softer compound.

I didnt know what to use either. So i went with a dual compound. They work way better than stock stuff. Definately tow them in though,they like to squeal otherwise.

I used this http://www.flickr.com/photos/plooifiets/2693243101/ one, before I switched to a hub brake in the front wheel. Now I still use the Koolstop at the rear. The brake is/was good, better than the old Brompton originals. I never tried the new Brompton pads.
