Eagle 12-Speed Ceramic Pulley System – Interbike 2018
There have been several companies offering ceramic pulley upgrades for Eagle drivetrains, but none look quite as good as the new kit from Enduro Bearings. Unlike other pulley systems, Enduro Bearings offers two pulleys and an idler.
The pulleys use ceramic bearings and aluminum centers that are 30% larger than the stock bearings that come stock on a SRAM Eagle derailleur. This increases the overall pulley stiffness and increases durability and shifting performance.
To reduce friction Enduro machines the pulley teeth our of Delrin and reduce chain wear as well. Enduro Bearings claims this design sheds mud and other debris better as well.
The whole kit retails for $300 and is available your local bike shop.
