10 tooth derailleur pulley source?
 

Having trouble finding 10 tooth replacement derailleur pulleys (new.) Searches just come up with 10 speed derailleur pulleys. I want both the guide and tension pulley.

Pulleys are for my old dura ace 7400 8 speed RD. (So technically the 7402?)

Any help?

EDIT: Apparently toronto cycles sells... aftermarket ones. All metal ones. I'd prefer the plastic ones as they're more quiet, but if I have to buy metals ones I will.

A quick search found these on ebay Shimano Rear Derailleur Pulleys 10T 6 7 8 Speed New Replacement Bicycle Parts | eBay

TACX also makes several versions of them with sealed bearings. You can find them on Amazon. Search "10t jockey wheels"

Thanks. Apparently "jockey wheels" is the more commonly used term in online listings.

The TACX ones are pretty... expensive. To the point where I could simply replace the entire derailleur. (They do look super nice though... pretty much exactly what I want.)

Actually, only the top one is correctly called a jockey wheel.

You can hear metal ones? I can't hear my Bullseyes. My wife says that I'm getting hard of hearing, but that's just selective listening

Interesting, was wondering that.

The derailleur I have comes with a metal guide pulley (jockey wheel) and a plastic tension pulley. When I bought the bike it was silent, but after I cleaned everything (the metal pulley was so dirty I couldn't tell it was metal, everything had a layer of grime on it) the drivetrain is actually quite a bit noisier. I'm wondering if I put the pulley on in the wrong direction, but looking at pictures of the stock pulleys, they don't have arrows on them.

Perhaps I tightened the bolts too much.

So yes, to answer your question, I CAN hear my metal pulley.
