Most durable derailleur pulley?

[ulrikmm]

A simple question: Which derailleur pulley (original or aftermarket) is the most durable?

A lot of the ones I have used over the years have durable aluminum or stainless steel cogs, whereas the single sealed ball bearing never lasts for long. Probably because the single bearing is subject to sidewards twisting, destroying the bearing fast.

Back in the 1970es, a small Danish manufacturer made pulleys with t w o minute sealed ball bearings side by side. Like in a bicycle hub. The Danish pros at the time used them season after season. The bearings never wore out, and only the cog material needed renewing.

Is anything like this still available?

Is ceramic bearings the answer?

Let me hear your experiences!

Depends what derailleur you're riding? I usually replace the jockey wheel on my ultegra derailleurs with the the DA one. The ultegra is a sleeve bearing with a craptastic rubber seal what often half way comes out and starts creating drag. The DA jockey wheel is a cartridge bearing.

I've found these to be very durable and a good price

Tacx pulleys, 15-20 dollars. Mine are great after 20k miles.
