CeramicSpeed OSPW Pulley Wheel System for Shimano 9000/6800 Series – Alloy Pulley, Carbon Cage, Black

Description

Upgrade your bike’s drivetrain performance with the CeramicSpeed OSPW (Oversized Pulley Wheel) System for Shimano 9000/6800 Series. Crafted for serious cyclists seeking enhanced efficiency, durability, and smooth shifting, this high-performance pulley system features premium materials and innovative engineering for optimal ride quality.

Materials & Construction

Constructed with hardened steel bearing races and Grade 3 Silicon Nitride balls, the CeramicSpeed OSPW ensures ultra-low friction and long-lasting durability. The robust cage combines lightweight polyamide with high-strength carbon fiber, providing superior resistance to wear while maintaining a sleek, aggressive aesthetic.

Performance & Engineering

Designed for seamless integration with Shimano Ultegra 6700/6770/6800/6870 and Dura-Ace 7900/7970/9000/9070 mechanical and Di2 rear derailleurs, this system optimizes power transfer and minimizes drivetrain inefficiencies. The oversized 17-tooth aluminum pulley wheels improve chain wrap and reduce flex, enhancing shifting precision and efficiency. Advanced bearing technology with ceramic/ Silicon Nitride balls ensures smooth rotation and reduced energy loss, allowing for a more responsive and efficient ride.

Components & Technology

Featuring two oversized alloy pulley wheels with high-grade bearings, the OSPW system reduces drivetrain friction significantly compared to standard pulleys. Its unique design improves chain management, decreases wear on drivetrain components, and allows for a quieter, more confident ride under load.

Style & Use Case
