This is the derailleur-type, a fairly well known one I'd say. Last week, the lowest pulley wheel came loose and fell out while riding. It happened at night but I was able to retrieve it the next day. I was probably a half mile from home so was able to make it home that night.
Now, I've installed it all back on the vintage ride and the rear derailleur seems to flex too much and I'm wondering if I even need to use such a long cage rear derailleur. Would a short derailleur work for a triple crank? Did something go haywire with this vintage Shimano Deore rear derailleur?
I do have a front derailleur for a Triple and the FD doesn't really seem to be the problem. The bike was going good for awhile but now, I can't get it back to how it was working.
I'm using it on a typical 10-speed cog cluster in back, so meaning 5-6 cogs, I have both on wheels.
The chain may be the culprit and I did get a new chain but as of now, today I tested it with the old chain.
I think the Triple crank part is okay, the problems to me, seem to somehow originate with the back part of the drive train.
Thank you earnestly for any answers and happy holidays.
