CERAMICSPEED OSPW Rear Derailleur Cage System Coated | Shimano Dura Ace 9200 / 9250 | Ultegra 8100 / 8150 | Cerakote Edition purple
The Oversized Pulley Wheel System (OSPW) from CERAMICSPEED is the logical consequence of minimizing friction. The oversized derailleur pulleys with 13 teeth at the top and a massive 19 teeth at the bottom significantly minimize the movement of the chain links when passing through the cage. This is noticeable in the lower friction and ensures a significantly longer service life compared to other commercially available systems.
The aluminum derailleur wheels from the Danish company CeramicSpeed represent the absolute high-end solution for all drivers who want to get the most out of themselves and their material in the race and for whom every watt saved is more important than anything else. Derailleur rollers and especially their bearings have to compensate for a lot of friction. Depending on the translation, these turn 4-5 times faster than the crank and thus benefit in particular from low-friction and durable bearing . The CeramicSpeed SpeedBalls balls are 15% harder than the competition and can absorb significantly more forces. They also have an incredibly smooth surface, which reduces rolling resistance to a minimum. All of these improvements have allowed the service life to be increased by 6 times.
Compared to the already high-quality standard bearings from CeramicSpeed, the "coated" version has a wafer-thin protective layer applied to the bearing rings. As a result, the latter become even harder, have a life cycle that is 60% longer and have even lower rolling resistance.
The optically striking bearing cage consists of carbon fibers which have been reinforced with polyamide. As a result, the forces can be absorbed and distributed better and your rear derailleur works perfectly even under the most adverse conditions. A coating of Cerakote has been applied for protection and longer durability. This is based on ceramic components and offers extreme abrasion resistance and unsurpassed hardness. You will be able to enjoy the eye-catching coloring for a long time and are guaranteed to draw many envious glances at your bike.
CeramicSpeed only uses the best materials and the latest technologies in production in order to always achieve the highest possible quality. All products are handmade in Denmark. Manual assembly eliminates manufacturing tolerances and always guarantees a 100% fit. So that you really only use the best on your bike.
The oil included in the scope of delivery is used for maintenance and has been specially designed for these bearings. Lubricants from other manufacturers are not recommended for this.
When travelling, please remember to dismantle the entire rear derailleur with an Allen key, as very few bicycle transport bags offer enough space for the OSPW system.
CeramicSpeed components are high-tech features for your bike. They offer you the highest performance, but also require regular maintenance and care. So please watch the videos below.
