CeramicSpeed Ceramic Titanium Coated Derailleur Pulleys - SRAM 1-11 Speed

The CeramicSpeed Ceramic Titanium Coated Derailleur Pulleys for SRAM 1-11 Speed are a direct-fit upgrade for SRAM 1x11 rear derailleurs — CNC-machined from titanium, fitted with Grade 3 Silicon Nitride ceramic balls, and finished with a three-micron metallic coating on hardened steel races. That combination addresses every weak point in a standard pulley: material strength, bearing friction, and resistance to contamination.

The titanium bodies are designed to outlast aluminum pulleys by a significant margin — and aluminum itself already outpaces the plastic pulleys found on most stock builds. The ceramic balls are manufactured to CeramicSpeed's tightest tolerances, with surface finish and roundness that the brand claims results in dramatically lower friction than standard steel or even conventional ceramic alternatives. The coated races go further still: the treatment is intended to reduce bearing friction by over 50% compared to standard CeramicSpeed ceramic bearings, extend service life by more than 60%, and resist water, dirt, and degreaser contamination to the point where corrosion-related bearing failure is effectively eliminated.
