Jockey Wheels on RD(5 posts)

The jockey wheels on my Dura-Ace RD are pretty chewed up, presumably from grit running through the chain over the years (I've replaced the chain and cassette). I'm going to replace them, but it's made me curious - I've never seen any bike repair manuals advise your to check for wear and replace the jockey wheels. Is this a rare problem? Also, why are they made of plastic? It seems they're quite easily damaged by a rock stuck in the chain or anything nasty like that.

There are some replacement wheels made out of aluminum, but I'd want plastic ones. If a rock got stuck in plastic wheels, the plastic breaks would break, possibly saving the chain.

I replaced the jockey wheels on my DA 7400 RD with Carmichael wheels. The aluminum wheels may be a little more noisy than the plastic and may require closer adjustment but the bearings are larger and smoother than the original.

Any mountain biker would know that if you get a twig or something caught in the lower run of your chain, you're in for bigger problems than broken jockey pulley! Usually the next thing you hear is the derailleur cage desintigrating among the spokes. Most of my mountain biking buddies have stopped using XTR rear derailleurs because an XT only costs a little over half as much to replace.

I just replaced mine and I am curious to see if there is any difference this weekend. When I was taking my bike apart to clean it the old jockey wheels feel apart.
