Littlepixel Hi I just found this thread and wanted to add this to the mix;
I ride folding bikes (just finished a brompton fixie - possibly a first?) and happen to know that the high end folding bike, the Airnimal, uses 520 wheels and that you can get a reasonable selection of tyres for it (or any other 520 wheeled beast from this shop should anyone feel the need to splash out...
I've dealt with them before and they're a really nice shop.
saw a fixed brompton, with massive gearing ages ago... sorry, the guy riding it was total pric though, so you can be the first decent person on a fixed brompton :)
