replacement derailleur jockey wheels?

[AngryScientist]

when i put together my geekhouse, i used a long cage tiagra RD. the bike sees a lot of mud, grit and grime, and after taking a look this past weekend, the jockey wheels look a little knackered. the rest of the RD is in great shape.

does anyone make these wheels of stainless steel?

what's a good replacement option?

Tacx with sealed stainless bearings are good as are the 105/Ultegra level pulleys, they have a sealed off ceramic bushing on the upper wheel.

I use this ones, made of aluminum:

Maintenance item in that application; I would replace with standard Shimano jockey wheels, available through Niagara or on eBay.

I have had good luck with the Tacx pulleys and they last a lot longer than my Shimano's.
