Everything from bearings to the cage on the CeramicSpeed OSPW is made from the highest quality materials. The oversized aluminum pulley wheels are fitted with coated CeramicSpeed Bearings, which reduce friction to the minimum. The overall power savings of the OSPW System for Shimano reach 30%-60% or more in some cases.
The CeramicSpeed oversized pulley wheel system has a lifetime that lasts 3-5 times longer than the commonly used standard pulleys on the market. This Shimano Dura-Ace 9100/9150 rear derailleur compatible version features an optimal 13/19-tooth combination specially developed to fit the design of this road bike rear derailleur.
This system has been proven to be the fastest pulley system in the world, providing energy savings starting from 2.4 watts over standard Shimano systems. The OSPW system is an industry-leading product, chosen by many of the world's leading cycling teams and professional triathletes.
IMPORTANT: When traveling, please remember to dismount your entire rear derailleur with an Allen wrench, as the OSPW System will not fit in most bike travel bags and could be damaged if left on.
