Review on Stylrtop Aluminum Bearing Derailleur Pulleys by Steve Snyder

I bought an orange bike and wanted to add bright colors here and there so I spent days looking for blue grips, saddles, rails, bells and on and on. When I first saw them I didn't know where they belonged on a bike! lol. At the bike shop I showed a photo to the tech to make sure they were the same size as my bike. The guy said they should be even better since I had plastic and these metal ones should last longer. My bike had Shimano brakes; They fit most Shimano rear derailleurs. If you get them, you can also get the blue bike chain! Once installed, they are hardly noticeable as they are small and almost invisible. I notice them because they're mine, but I doubt others will notice. An advantage is that they are stronger than the plastic parts that come with the bike.
