CeramicSpeed 3D Printed Ti OSPW RS System (Black/Oil Slick) (Shimano 9250/8150) (Coated Ceramic Bearings)

CeramicSpeed 3D Printed Ti OSPW RS System Description:

The CeramicSpeed 3D Printed Ti OSPW RS System for Shimano Road Dura-Ace R9250 and Ultegra R8150 rear derailleurs represents a leap forward in drivetrain efficiency, durability, and looks. The updated injection molded polyamide and carbon fiber cage body is incredibly stiff and has 4 customizable spring tension settings that will allow for very snappy shifts and improved chain retention. The pulleys are created out of 3D printed hollow titanium that has been PVD coated, which results in pulley wheel bodies that are highly resistant to wear and tear while being unthinkably light. These beautiful pulleys roll on hand-built CeramicSpeed bearings stuffed with Grade 3 Silicon Nitride balls that roll on specially coated races that results in a significant reduction of the parasitic losses usually found in derailleur pulleys, and these bearings will perform better for far longer than a similar in size steel bearing or the bushings typically found in derailleur pulleys.

Features:

• Premium 3D printed hollow titanium 13-tooth upper and 19-tooth lower pulley wheels are remarkably durable and exceptionally lightweight
• Unique physical vapor deposition (PVD) oil slick coating on the pulley surface provides great looks and resistance to wear and tear
• Robust injection molded cage crafted from polyamide and carbon fiber for durability and light weight
• Hand built CeramicSpeed coated bearings featuring Grade 3 Silicon Nitride balls installed in each pulley for the ultimate reduction of drivetrain drag, long life, and light weight
• Coated bearing races increase bearing service life by increasing hardness of race and reducing corrosion
• 4 customizable spring tension settings to dial in the chain retention and shifting performance of the rear derailleur
• Compatible with Dura Ace 9250 and Ultegra 8150 series (Fits 11-30 and 11-34 Shimano 12spd Cassette options)
