Hey all,
Love this site. I have a 10 year old Trek 6000 that has a Deore LX rear derailleur. I recently replaced the original chain with a new SRAM chain. It went on fine and I did some slight adjustments on the derailleur, lubed it up and took the bike for a test ride. It's so smooth and quiet now. However, I'll be riding along fine and all the sudden I'll hear the derailleur being pulled and then snapping back into position. It's not much of a pull because I don't really feel it, I only hear it. There is no pattern to it and it doesn't necessarily do it when I'm pedaling fast or slow or hard up hills or anything. It just does it randomly. A couple times it pulled the derailleur enough that the chain got caught up in the bottom section of my front derailleur and I was forced to stop. When I first installed the new chain, I broke the chain at the same length of the old one and installed it without a quick release link. I rechecked the chain and the pins are all set ok and don't appear to be sticking out too far that they would catch anything. Also, I hung my bike in the garage and just went through the gears by hand and couldn't replicate the problem so it's like it only happens under load. Any ideas?
