Similar thing happened to one of my touring buds a couple of weeks ago. It was a 9 speed and he's a big guy who pounds the pedals. First time was on a climb and he was able to take out the offending link to get going. Later in the same ride it started making noise on a flat section and he found one of the outer plates hanging loose, just waiting to fall off. As far as I know, he just replaced the chain and did not find any obvious cause.
I've never had a chain fail but have seen it happen, usually older bikes that have been neglected. Never on one such as your son has. dougP -----Original Message----- From: rbw-owners-bunch@googlegroups.com [mailto:rbw-owners-bu...@googlegroups.com] On Behalf Of GeorgeS Sent: Tuesday, April 28, 2009 8:03 PM To: RBW Owners Bunch Subject: [RBW] Query Concerning Chain Problem My son has a Romulus he purchased about six months ago. Several weeks ago he was out on a long ride and his chain broke. I have been riding bikes a long time and I've never had a chain actually break in use and I've never known anyone who has had that happen. He said that on examination the outside plate simply peeled back at several places and separated from the pin. That left the inner plate holding the chain together and then that went. He said he did not hear any noise until shortly before the chain broke and it was obviously the plates hitting the RD cage. He took the bike back to the bike store where he bought it and they said they had never seen such a thing and put it off to a defective chain which they replaced and sent him on his way. On Sunday the same problem started to happen. After about 30 miles he said he started to see the plate on the outside start peeling back at three points on the chain. This time he was able to get back to the car before the chain broke. The bike store kept the bike to show to their ace mechanic and my son is supposed to pick it up later in the week. Anyone ever heard anything like this? The cranks are Sugino and the derailliers are 105's. He is riding on good roads in Maryland right out of DC.
