Sram Eagle XD-15 Derailleur Pulleys and Idler Pulley


Our Enduro bearings pulleys for the Sram Eagle 12-speed system have been completely re-designed to increase shifting performance, and reduce overall friction. We start by machining aluminum centers that are 30% larger than a standard bearing pressed in to a plastic pulley wheel. The aluminum centers increase the overall stiffness of the pulley, translating into faster shifts with no lag and more precise shifts to the desired cog. XD-15 bearings are housed within the aluminum centers. Each upper and lower XD-15 bearing differ and are specific to their separate duties for less friction and improved shifting performance. To reduce chain friction the pulley teeth are machined from 500 AF Delrin® with Teflon®, offering significant less drag than pulleys manufactured from aluminum or titanium. The overall smooth profile sheds mud and debris, providing easy clean up after riding in less than ideal conditions. Our shift cable idler replaces a plastic roller and bushing with another XD-15 bearing. The design of the idler reduces shift friction by a noticeable amount, especially shifting up to the larger cogs that see teeth differences between 6 to 8 teeth between cogs.
