The LTWOO Super Speed Pulley System (SPI System) was developed to meet the increasing demands of cyclists to improve drivetrain performance. Due to the extremely low friction of LTWOO high speed bearings and the unique design of the entire system, the SPI system can optimize the overall efficiency of the drive system.
OSPW system for Shiman 9100/9150 and 8000 SS / 8050 SS
This is an updated version of the Shiman 9100/9150 and 8000 SS / 8050 SS oversized pulley systems. Installation instructions for this version and older versions can be found in the "support" section.
This new design has a built in limit tower for easy installation.
The LTWOO super large pulley system has proven to be a fast pulley system. Compared to the standard Shiman system, the energy savings is only 2.1 watts.
The SPI system suitable for Shimano 9100/9150 and 8000 SS / 8050 SS is an industry product and has been chosen by many world cycling teams and professional triathletes.
With the 13 tooth upper pulley and 18 tooth lower pulley, the rear derailleur can be absolutely optimized. The upper and lower oversized aluminum pulleys are equipped with standard or coated ceramic.
Please note: SPI systems for 9100/9150 and 8000 SS / 8050 SS are not compatible with the Ultegra 8000-GS or 8050-GS (medium cage) front derailleur, nor with the Ultegra RD RX800 and RX805 equipped with clutches.

Durable: The bicycle rear derailleur pulley wheel is made of aluminum alloy, carbon fiber and tabua, the guide wheel is solid and durable. Features: to your drivetrain for maximum efficiency and superior reproduction. Wheel bearings reduce friction, giving you lower rolling resistance. The osmo from the wheel bearings to a large pulley will maximize the return on your energy. ❀In the efficiency of the changes: this guide wheel can coincide closely with the fall, reduce the virtual lateral position, shorten the response time of the change and increase the efficiency of the changes. Reduzir or energy consumption by friction: uses palin totally 18 / mico resistance to or sin, reduced or energy consumption by friction.
