The principle is straightforward: larger pulleys create a smoother chain path, and ceramic bearings running inside those pulleys eliminate the friction that steel bearings generate. CeramicSpeed has measured the result at 35–40% less friction than a stock pulley configuration — free speed that doesn't ask anything of your legs.\u003c\/p\u003e\n\n  \u003cp\u003eThis is the Coated variant, which upgrades the bearings further. Where the standard version uses CeramicSpeed's silicon nitride ceramic balls, the Coated version adds a specialized friction-reducing coating to the bearing surfaces. CeramicSpeed's ceramic balls are already 58% lighter than steel and significantly faster — each one takes 50 to 70 days to produce. The coating builds on that foundation, extending bearing life and reducing friction even at the contact points that standard ceramic already handles well.\u003c\/p\u003e\n\n  \u003cp\u003eThe cage itself is custom molded carbon fiber, keeping system weight minimal while maintaining the structural rigidity needed to hold precise pulley alignment under load. The 15-tooth upper and 19-tooth lower pulley wheels are machined aluminum. Two spring tension settings let you dial in chain wrap based on your cassette and riding conditions. Installation uses a custom tool included in the box, and CeramicSpeed includes a 15ml bottle of UFO Tech Bearing Oil and a full installation guide.\u003c\/p\u003e\n\n  \u003ch3\u003eSpecs at a Glance\u003c\/h3\u003e\n  \u003cul class=\"specs_at_a_glance\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eCompatibility:\u003c\/strong\u003e SRAM Red eTap AXS and Force eTap AXS 12-speed\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003ePulley sizes:\u003c\/strong\u003e 15-tooth upper \/ 19-tooth lower\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eCage material:\u003c\/strong\u003e Custom molded carbon fiber\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003ePulley material:\u003c\/strong\u003e Aluminum\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eBearings:\u003c\/strong\u003e Coated ceramic (silicon nitride balls with friction-reducing coating)\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSpring tension:\u003c\/strong\u003e Two adjustable settings\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e Black\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eIncludes:\u003c\/strong\u003e OSPW system, UFO Tech Bearing Oil 15ml, custom installation tool, installation guide\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMade in:\u003c\/strong\u003e Holstebro, Denmark\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003ch3\u003eDesign Benefits\u003c\/h3\u003e\n  \u003col class=\"design_benefits\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eCoated ceramic bearings:\u003c\/strong\u003e The premium step up from standard ceramic.
