CERAMICSPEED - OSPW AERO ALPHA DERAILLEUR CAGE - SRAM FORCE / RED AXS

The CeramicSpeed OSPW Aero ALPHA system for SRAM Red and Force AXS derailleurs updates the fastest proven aero derailleur cage to include our patent pending ADR bearing protection and quiet performing ALPHA disc with composite tooth profile pulleys. Furthermore, a speed defying pinstripe graphic has been added for a splash of visual motion.

The OSPW Aero ALPHA cages have been updated to accommodate the ADR equipped ALPHA disc pulleys. It is not possible to add these pulleys to a previous gereration OSPW Aero cage.

The design of the OSPW Aero refines aerodynamics by focusing on frontal area impact, as well as smoothing and controlling the trailing wind. With podiums in World Tour stages and the Men's and Women's IM World Championships in St. George to its name, the OSPW Aero has demonstrated its impact at the highest level of racing. Wind tunnel testing shows that the OSPW Aero locally reduces drag by 40% on average and at some points up to 60% compared to a stock derailleur. For all the science, data, and info about testing, read the full white paper here.

• Reduces aerodynamic drag on the rear derailleur by up to 60%
• Reduces friction 35-40% over stock pulley configuration
• Structural aerodynamic cage design
• Pulleys, cages, and bearings all produced and assembled by hand in Denmark
• ALPHA Disc pulleys with composite teeth for quiet performance and ADR bearing protection
  
  

"The CeramicSpeed OSPW has class leading aerodynamics for its size. Given that this only represents about 1% of the total system drag, we knew that we had a challenge on our hands particularly as the rear derailleur cage sits on the most complicated area of flow on the bike, and also given the position and angle changes. This is one of the most complex areas of the bike to develop"

- Simon Smart, founder of Drag2Zero

Please note While there are visual similarities with the SRAM RED/Force AXS derailleurs, this OSPW system is not compatible with the SRAM Rival AXS derailleur.

The Story

CeramicSpeed is one of the world’s leading suppliers of ceramic bearings. The company consists of two specialised sales channels, focusing on cycling and industrial applications.

We have more than 15 years of experience in bearings applications, and we have developed close relationships with our component suppliers over the time – each of whom is the very best in their fields. The CeramicSpeed Sports channel delivers both bearings as well as ultrafast racing chains, reinforcing the company’s goal of saving watts and delivering the lowest friction available. All our bearings are handmade and our chains are optimised by hand in Denmark.
