The CyclingCeramic OSPW Pro for Shimano Ultegra and Dura-Ace drivetrains is engineered to deliver a significant improvement in drivetrain efficiency, precision, and overall performance. Designed for performance-focused road cycling, the oversized pulley system optimizes chain movement, allowing for smoother shifting and more efficient power transfer across a wide range of riding conditions.
At the core of the system is a precision-engineered oversized pulley configuration featuring a 14-tooth upper and 19-tooth lower pulley. This design reduces chain articulation and mechanical resistance, resulting in improved drivetrain efficiency and enhanced responsiveness during both high-speed efforts and sustained climbs.
Constructed using CNC-machined aluminium pulley wheels combined with a carbon UD rear plate and aluminium front plate, the OSPW Pro achieves an optimal balance between lightweight performance and structural durability. The aerodynamic profile further enhances drivetrain efficiency, contributing to overall speed gains on the road.
The system is equipped with hand-built ceramic bearings specifically optimized for Shimano Ultegra and Dura-Ace drivetrains. These bearings significantly reduce friction during gear transitions, delivering ultra-smooth shifting performance and improved energy efficiency.
Independently tested by friction analysis specialists, CyclingCeramic systems have demonstrated exceptionally low friction levels, helping riders achieve measurable gains in drivetrain performance and precision.
Compatible with both Shimano 11-speed and 12-speed Ultegra and Dura-Ace groupsets, the OSPW Pro integrates seamlessly into modern road bike setups, making it a premium upgrade for riders seeking enhanced drivetrain efficiency and reliability.
At Mastermind Bicycle Studio, the official distributor of CyclingCeramic in India, the OSPW Pro for Shimano Ultegra & Dura-Ace is available for riders looking to elevate their drivetrain performance with a high-precision upgrade.
