I have Mavic 520's , 32 hole 3X. On wolber profil clinchers, never braked on. hubs beautiful, VVGC no patina on them. I'm after £250 and postage would be about £20 ( only within the UK, I won't be sending abroad.)if you're interested let me have your email I'll send some pics. If you're in Edinburgh you could see them first.
