This is an updated version of the 3D-Printed Ti OSPW for Shimano 9100/8000. This new design has an integrated stop tower for easier mounting.
The CeramicSpeed Oversized Pulley Wheel System has been proven to be the fastest pulley system in the world, providing energy savings starting at 2.4 watts over standard Shimano systems.
The OSPW System for Shimano 9100/8000 is an industry-leading product, chosen by many of the world's leading cycling teams and professional triathletes. Featuring a 13-tooth upper pulley wheel and a 19-tooth lower pulley wheel to provide absolute optimization of the rear derailleur, the upper and lower oversized aluminum pulley wheels are fitted with coated CeramicSpeed Bearings for even longer lifetime and lower friction.
