So long as your 9-10 speed rear derailleur is still performing, improve its performance with pulleys that reduce mechanical drag and increase bearing life. You’ll go faster with the same effort. 

Whether you’ve got a Sram, Shimano or Campag 9- or 10-speed rear derailleur, we have three alternatives. One is our machined aluminum pulleys with our stock CeramicSpeed Balls in hardened-steel races; our Standard Bearings. These spin with less drag than anything on the market. The second option is machined titanium pulleys with our Standard Bearings. The third is machined titanium pulleys with our stock CeramicSpeed Balls installed in coated hardened-steel races; our Coated Bearings.
