CeramicSpeed OSPW Aero Dura Ace 9250 - Ultegra 8150 Oversized Pulley Wheel System | Coated | Black

OSPW Aero for Shimano 9250 and 8150

The world’s fastest Pulley Wheel system just got faster. OSPW Aero features a lifetime warranty and is wind-tunnel tested to have 40% less friction compared to a stock derailleur, making it perfect for time trials or triathlons.

The OSPW Aero is an industry-leading product co-developed with one of the world’s leading aerodynamicists; Simon Smart and is chosen by World Champions and top athletes around the world. This OSPW system has handbuilt CeramicSpeed Bearings installed and its unique design and craftsmanship will captivate you from the first time you use it.

The system features a 13-tooth upper Pulley Wheel and a 19-tooth lower Pulley Wheel to provide absolute optimisation of the rear derailleur and the upper and lower oversized aluminum Pulley Wheels come fitted with coated CeramicSpeed Bearings that have been perfected through years of experience.

The OSPW Aero for Shimano Dura Ace 9200 and Ultegra 8100 has an integrated stop tower for simple installation and durability.

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.

What is Coated?

Our coated products is covered by a lifetime warranty. The unique coating formula is a metallic layer that covers the bearing races and makes them 75% harder than steel. Thanks to this, they are highly resistant to corrosion and the coating provides an even lower friction than our standard bearings. Even if the bearing is contaminated with degreaser, water or mud, the risk of bearing failure due to corrosion is negligible if you choose the coated version.

Ceramic Speed coated bearings are a true technological masterpiece, providing an incredible advantage. Compared to standard bearings, they open new possibilities for both professionals and enthusiasts. Here are the main advantages of coated bearings, clearly and understandably:

High resistance: With a metallic coating, Ceramic Speed coated bearings are 75% harder than standard steel bearings. Hardness here is the key to longevity and reliability – these bearings can withstand significantly higher usage intensity and pressure, giving cyclists peace of mind even under the most extreme riding conditions.
Corrosion protection: One of the biggest challenges for any bicycle part is protection against corrosion, which can be caused by contact with water, dirt, or even cleaners. Ceramic Speed coated bearings feature exceptional corrosion resistance, making them an ideal choice not only for daily use but also for extreme conditions, such as riding on muddy trails or in the rain.
Lower friction: Friction is a key factor determining the efficiency of bearings. Lower friction means less energy wastage and, correspondingly, greater efficiency. Ceramic Speed coated bearings ensure an extremely low level of friction, giving the cyclist the ability to achieve the best results with less effort.
Lifetime warranty: The manufacturer's lifetime warranty is not only a mark of confidence in their product but also provides additional value and peace of mind for the user. This warranty indicates that by purchasing these bearings, you can be sure of their reliability and longevity.
Durability under tough conditions: Even under the toughest conditions, such as exposure to water or dirt, Ceramic Speed coated bearings maintain their characteristics thanks to the advanced coating. This means that their performance and longevity remain at the highest level regardless of external factors.

Ceramic Speed coated bearings are not just a high-quality choice for your bicycle, but also an investment in smoother, more efficient, and longer-lasting performance. Whether in daily commutes or competitions, these bearings provide the cyclist with an advantage and the highest level of reliability.
