It's a 7 spd. canti-braked Santana. They haven't had it on a stand yet. They've ridden it for years with no probs--they know what it should feel like. It just started to do this on a ride--when they stopped pedaling, the bike felt as though someone was applying a brake. On a downhill, they normally FLY even coasting, but now had to pedal least they slow to a crawl. Does this info help?
