i loved my avid bb7's on my recent tour of Yunnan Province China..... LONG grades there. Unpredictable road conditions - animals, potholes, abrupt short sections of dirt road where landslides were so common that repaving made no sense, folks herding pigs-goats-yaks-geese, piles of building material, grain threshing activity, rice drying, giant piles of manure for the crops, parked farm vehicles - all right in the roadway. those brakes got a workout. used the organic pads, liked them
