3D-Printed Hollow Titanium Pulley Wheels
The standout feature of this OSPW RS system is its 3D-printed hollow titanium pulley construction. Titanium offers excellent strength, durability and corrosion resistance, while the hollow printed design helps keep weight low without compromising the premium feel expected from CeramicSpeed.
CeramicSpeed Coated Bearings
The system uses CeramicSpeed coated bearings, designed to reduce rolling resistance, improve bearing lifespan and deliver smoother drivetrain operation. Compared with standard steel-bearing pulley systems, CeramicSpeed bearings are engineered for lower friction and improved durability when maintained correctly.
Oversized Pulley Wheel System
The oversized pulley design reduces the angle at which the chain bends through the rear derailleur. Less chain articulation can reduce drivetrain friction, helping improve efficiency during sustained efforts, sprinting and high-cadence riding.
Reinforced OSPW RS Cage
The updated RS cage design is more angular, modern and reinforced compared with earlier OSPW systems. It is built to improve strength and durability while visually matching the sharp design language of current high-end road bikes and Shimano 12-speed Di2 groupsets.
Oil Slick PVD Finish
The Oil Slick finish is created through a PVD surface treatment process, giving each unit a unique rainbow-style appearance. Colour tone can vary slightly from piece to piece, which adds to the custom boutique nature of the product.
Efficiency-Focused Drivetrain Upgrade
This is not just an aesthetic upgrade. The combination of oversized pulleys, premium coated bearings and titanium construction is designed to reduce drivetrain drag and improve mechanical efficiency, particularly for riders focused on marginal gains.
