CeramicSpeed Ceramic Titanium Derailleur Pulleys - SRAM 1-11 Speed

Most drivetrain watts are lost in places you can't see — the CeramicSpeed Ceramic Titanium Derailleur Pulleys for SRAM 1-11 Speed address one of them directly. CNC-machined from titanium and built around Grade 3 Silicon Nitride ceramic balls running in hardened steel races, these pulleys are engineered to reduce frictional drag to a figure that approaches negligible. Titanium construction is designed to last approximately four times longer than the aluminum alloy pulleys it replaces — which itself outlasts the standard plastic.

The ceramic balls CeramicSpeed uses are produced to tight tolerances, with the manufacturer citing 400% smoother surfaces and 128% greater hardness compared to standard steel balls. The bearings are assembled in dust-free clean rooms and intended to outlast conventional sealed races by three to five times the normal service life. Installation requires only a 2.5mm Allen key — the upper and lower pulleys are not interchangeable, so orientation matters, and the original SRAM spacers should be retained and reused. Periodic maintenance is straightforward: a drop of thin oil at the seal edge after chain lubing or a wash keeps drag at its lowest.
