Accessories for bicycle derailleurs

The OSPW system optimizes the overall efficiency of your drivetrain thanks to its unique design and extremely low-friction bearings. The OSPW system from Ceramicspeed is arguably the best way to optimize performance. The large 13-tooth upper and 19-tooth lower pulley wheels significantly minimize chain link movement as it passes through the cage, thereby significantly reducing friction and effort. In addition, the lifespan is significantly extended compared to other commercially available systems. The derailleur pulley wheels are also made of aluminum. These represent an absolute top-tier solution for all riders who want to get the maximum out of themselves and their equipment in races and for whom every saved watt is more important than anything else. The derailleur pulley wheels, and especially their bearings, must compensate for high friction, which is why they benefit from durable, low-friction bearings. Ceramicspeed SpeedBalls are 15% harder than competing ones and can absorb significantly more force. They also have an incredibly smooth surface, which reduces rolling resistance to a minimum.
