Bulls eye jockey wheels worth it???

I saw some Bullseye jockey wheels on the 'bay, starting at about $45. I can get the standard issue plastic/resin ones for about a quarter of that.
Hence, my quandry. Do the Bullseye ones last longer than the OEM ones? Are the Bullseye wheels worth it?

Thanks for your input.

$45 is pricey for a jockey wheel. If it has the fancy bearings that don't allow float, it can actually make the drivetrain sound louder then stock. I would stick with the stock wheels.

The Friction Facts people put jockey wheels / pulleys to the test a couple of times. The difference between the best and worse was slightly more than 1 watt. And that's for the pair of them. Shimano Acera was the worst at 1.37 watts closely followed by the Campy Chorus and Shimano 105 pulleys.

The best were those with ceramic bearings with the CeramicSpeed Hybrid Gr3 leading the pack at 0.033 watts.

Bulls Eye pulleys were not tested, but as the worst pair only consumes a little over 1 watt, I don't see how they can make all that much difference.

As far as durability, I've never worn out a pair of pulleys. Usually the rear derailleur needs changing before that.

If you're worried about anything on the RD wearing out, put some threadlock on the bolt that holds the jockey wheel to the cage. That's the only time I've ever had an issue with a jockey wheel (when it has gone missing).

I have actually worn out a couple of sets of jockey wheels. It usually takes a couple of years for me to do that.

never worn out pulleys on my own bikes .
but on customers' bikes the only time I see it happen is when they let a worn chain run too long and it kills the teeth (as well as the teeth on cassettes and chainrings)

they look like they might make pretty keychains

Haven't worn out the bearings, but I have had the teeth of the top pulley get worn thin from pushing the chain side to side when shifting (~10,000 miles). The thin teeth make the shifting a bit more sloppy. FWIW: Shimano top pulleys have axial float. In my experience, SRAM does not.

Lo friction ceramic jockey wheels?

Makes sense with something like this:



Not really worth it for a regular road bike though.
