Han, Were they Shimano or Avid? A mate has Avid BB7's on both a touring bike and an ATB, he loves them. Better than the BB5's on his short-lived Boardman 'crosser! Had a nasty experience on the 'crosser 15 months ago; the rims picked up moist snow then iced up, hence looking to get away from rim brakes for off-road and winter!
