Stylrtop 2 pcs Bike 11T Aluminum Sealed Bearing Jockey Wheel Rear Derailleur Pulleys (Blue)

Hardly noticeable, but stronger I bought an Orange bike and wanted to add color pop here and there, so I spent days looking for Blue grips, saddles, rails, bells, and on and on. When I first saw these, I didn’t know where they belonged on a bike! lolAt the bike shop, I showed the picture to the tech to make sure they’re the same size as what my bike needs. The guy said these should be even better, since mine came with plastic ones, while these are metal and should last longer.My bike had Shimano breaks; These…

Easy cheap upgrade One of these arrived with an apparent broken bearing.. It barely spins and actually will stop and start to rotate the other way as if there is something in the bearing, physically causing resistance. The other seems to be fine (though it barely spins with the caps on, this should not be the case with a brand new bearing.), so these bearings aren’t the best. Considering I bought these for a prototyping project, and mostly wanted it for testing purposes, these will work. I will probably buy some…

Product was delivered very quickly. I would have liked some direction about lubrication and installation, but that’s not a deal breaker for me. Bottom line is that they spin much more freely than the stock pulleys on my 105, the drive train feels smoother and sounds quieter. Example… when I have my bike on a rack for service and I manually spin the crank, it keeps on spinning after I stop pushing them for a rotation or two. It didn’t do that before adding the pulleys, a half rotation at most…
