Our machined titanium pulleys last three times longer than those made of machined aluminum.
Our Coated Bearings last 60% longer than our standard bearings. Drag is decreased by over 50% compared to our standard bearings.
A set consists of differing upper and lower pulleys, they are marked as such, and have directional arrows etched on them so you know exactly how to install them.
These pulleys are compatible with all Shimano 11-speed rear derailleurs that aren’t XT or XTR.
The kits come with CeramicSpeed oil in a 15ml dropper bottle. The bearings come with oil in them already. The oil is to keep them running smoothly.
