The Oversized Pulley Wheel System for Shimano Dura Ace 9200 and Ultegra 8100 with integrated stop tower for simple installation and durability.
The CeramicSpeed Oversized Pulley Wheels System has been proven to be the fastest pulley system in the world.
CeramicSpeed OSPW Systems are an industry leading product, chosen by World Champions and top athletes around the world.
This OSPW System has handbuilt CeramicSpeed Bearings installed in each pulley and comes with a 4 year warranty as standard and a lifetime warranty when choosing coated or SLT bearings.
Featuring a 13-tooth upper pulley wheel and a 19-tooth lower pulley wheel to provide absolute optimisation of the rear derailleur. The upper and lower oversized aluminium pulley wheels come fitted with either standard or coated CeramicSpeed Bearings.
Please note while there are visual similarities in the 9100 Series OSPW and 9200 Series OSPW, the spring tension settings, rotation stop tower placement, and mounting pin depth are slightly repositioned and as such the systems are not cross compatible. The 12spd Shimano R-7150 105 is not supported at this time.
For 8100 derailleurs, the cage uses the factory derailleur body washer. 9200 derailleurs will require the new included derailleur body washer.









 
				


 CeramicSpeed is more than just bearings. We are a company founded on innovation and a relentless desire to change the world of competitive cycling. We’ve grown rapidly over the years, distributing to over 50 countries, with an ever expanding team of unique individuals in offices across Europe, Asia, and America.
CeramicSpeed was founded, and we started producing hybrid bearings in Holstebro, Denmark, for both sports and industrial applications.
Using technology developed as part of NASA’s space program in the 1990s, our hybrid bearings are made with top-grade silicon nitride ceramic balls, making them 58% lighter and 30-50% faster than traditional steel bearings. The production of each ball takes from 50 to 70 days, but the result is worth the wait.
The acquisition of the Colorado-based testing lab, Friction Facts, in 2016 bolsters our ability to deliver efficiency, quality, and groundbreaking results within the cycling industry. Innovation is in our DNA, continuously bringing new and improved products to market, setting new standards, and pushing the boundaries of the cycling technology.
Today, people are the heart and soul of our company. Operations are still based at our headquarters in Holstebro, where the team continue to assemble every single bearing by hand. While the company keeps growing in all corners of the world, our culture and values remain rooted in our history.
