It features a 13-tooth upper pulley and a 19-tooth lower pulley, both running on ultra-smooth ceramic bearings. A lightweight carbon cage is also used. Compared to the previous model, installation has been simplified with the addition of a stop pin. Like all Oversized Pulley Wheel (OSPW) systems from CeramicSpeed, the Shimano version offers reduced friction compared to standard pulleys, allowing for significant energy savings. In the Coated version, there are additional benefits: a metallic coating on the bearing races enhances the already high performance, increases durability, and nearly eliminates bearing wear.
