3D Printed Hollow Titanium pulley wheels for Shimano 11-speed derailleurs are lighter than our machined titanium pulleys and just as resistant to wear. They’re fabricated out of titanium powder and are machined and surface-hardened after printing.
They run on our coated-race CeramicSpeed bearings to further increase durability and reduce friction. The hardened-steel races increase corrosion resistance and better deal with imperfect environments.
The weight savings gained by switching from machined titanium is 5-10% per pulley.
The material benefit is a three-fold increase in the lifetime of the pulley over aluminum.
The Coated Bearings have races 75% harder than our hardened-steel races. They last 60% longer than our standard bearings. Drag is decreased by over 50% compared to our standard bearings.
There are different upper and lower pulleys, are marked as such, and have directional arrows etched on them.
These pulleys are compatible with all Shimano 11-speed rear derailleurs, both mechanical and electronic. The included spacers work only with Shimano 11-speed rear derailleurs.
