SRAM RED E1 Rear Derailleur with CeramicSpeed Alpha RS OSPW

SRAM RED E1 Rear Derailleur with CeramicSpeed Alpha RS OSPW

The SRAM RED E1 Rear Derailleur with CeramicSpeed Alpha RS OSPW is a unique offering where we professionally install the CeramicSpeed OSPW onto a new SRAM RED E1 Rear Derailleur. This gives you a ready-to-use upgrade out of the box. It saves time, ensures proper installation and eliminates the need for additional tools or mechanical work. Just mount the derailleur and start riding with pro-level efficiency!

The SRAM RED E1 Rear Derailleur is the heart of SRAM’s most advanced road drivetrain. Designed for 12-speed wireless systems, it offers lightning-fast shifts and is SRAM’s lightest road rear derailleur ever. With AXS integration, it can be easily adjusted and seamlessly integrates with your SRAM components.

To push efficiency even further, we’ve paired this derailleur with the CeramicSpeed Alpha RS OSPW. Featuring a lightweight carbon-reinforced cage, premium ceramic bearings and a redesigned cage shape, the Alpha RS reduces drivetrain drag. This means more of your power is transferred to the wheels and not lost in your drivetrain. This OSPW uses 15T upper and 19T lower oversized pulleys. This minimizes chain articulation which minimizes drag and improves chain life.

CeramicSpeed’s updated cage design not only improves aesthetics, but also makes the derailleur cage stronger. This provides better shifting, especially under load. The Active Debris Remover shields also make it virtually impossible for debris to enter the bearings.

Please note, the SRAM AXS Battery is sold separately. It is also recommended to use a new chain as the CeramicSpeed OSPW system requires a longer chain than the stock derailleur cage.

Compatibility

The SRAM RED E1 rear derailleur and CeramicSpeed OSPW work with SRAM AXS 12-speed road drivetrains. It is compatible with all sizes of SRAM cassettes, including 10-36T and SRAM Flattop chains.

Considerations

These are both premium components that improve drivetrain efficiency, but come at a premium cost. In addition, we have found that CeramicSpeed OSPWs perform best when they are properly maintained (cleaned and greased), so this setup is best for someone who maintains the condition of their bike’s drivetrain.

Advice From Our Staff

We believe this is a perfect choice for road cyclists, time trialists or triathletes who are looking to maximize drivetrain efficiency. Our team has never had quieter drivetrains than when using this set up. It’s pricey for sure, but if you’re looking for smoother shifting, reduced drivetrain drag and an improved look of your rear derailleur, this setup delivers.

Professional Assembly

We are happy to professionally assemble the OSPW to your rear derailleur. This ensures your OSPW is correctly installed and saves you time. Professional assembly includes:

• Removal of the stock derailleur cage

Please note – while we tighten everything to factory specs, it is still your responsibility to routinely check your rear derailleur and OSPW to make sure all bolts and nuts remain securely fastened.
