CeramicSpeed OSPW RS ALPHA derailleur cage for SRAM Red/Force AXS, black
CeramicSpeed OSPW RS ALPHA derailleur arm for SRAM Red/Force AXS
The OSPW system optimizes the overall efficiency of your drivetrain thanks to its unique design and extremely low-friction bearings.Ceramicspeed's OSPW system is probably the best way to optimize performance. Large derailleur pulleys with 13 teeth at the top and 19 teeth at the bottom significantly minimize chain link movement as it passes through the cage, significantly reducing friction and effort. In addition, the service life is significantly extended compared to other commercially available systems.
The derailleur pulleys are also made of aluminum. They represent the absolute top solution for all riders who want to get the most out of themselves and their equipment in the race, and for whom every saved watt is more important than anything else. Derailleur pulleys and especially their bearings have to compensate for high friction, so they benefit from a durable, low-friction bearing. Ceramicspeed SpeedBalls are 15% harder than the competition and can absorb significantly more force. They also have an incredibly smooth surface, reducing rolling resistance to a minimum.
