SRAM RED E1 XPLR Rear Derailleur with CeramicSpeed X Alpha OSPW
The SRAM RED E1 XPLR Rear Derailleur with CeramicSpeed X Alpha OSPW is a unique offering where we professionally install the CeramicSpeed OSPW onto a new SRAM RED E1 XPLR 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 RED E1 XPLR AXS Rear Derailleur is made specifically for gravel and SRAM’s 13-speed drivetrain. This means you have plenty of gear range for fast gravel road and technical climbs. Built around SRAM’s UDH interface, this derailleur is free from adjustment screws and bent hangers. This makes set-up easy. It also means that the SRAM RED XPLR Rear Derailleur can handle sticks, rocks, mud and even airport baggage abuse. Like all SRAM Transmission derailleurs, this one uses a Magic Wheel so your drivetrain will continue to run even if debris enters the lower pulley wheel.
To push efficiency even further, we’ve paired this derailleur with the CeramicSpeed X Alpha OSPW. Drivetrain efficiency is crucial, even in off-road riding. Featuring a lightweight carbon-reinforced cage, premium ceramic bearings and a redesigned cage shape, the X Alpha reduces drivetrain drag. This means more of your power is transferred to the wheels and not lost in your drivetrain. This OSPW uses 14T upper and 20T 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.
Product Details
Key Features
- Installed and Ready to Go: We take the hassle out of installation by combining two high performance products into one seamless upgrade. This is done at no additional cost, just the price of each component.
- SRAM RED E1 XPLR Rear Derailleur: The RED E1 XPLR rear derailleur offers fast and reliable shifting, even under extreme load.
- CeramicSpeed X Alpha OSPW: Redesigned for improved stiffness and efficiency, this OSPW features a lighter cage, ADR shields and premium ceramic bearings.
- Improved Drivetrain Efficiency: The X Alpha OSPW improves drivetrain efficiency by reducing friction, allowing you to maintain speed with less effort.
- Clean Aesthetic: A visually sleek setup that improves the look of any bike.
Compatibility
The SRAM RED E1 XPLR rear derailleur and CeramicSpeed OSPW work with SRAM AXS 13-speed gravel drivetrains. It is compatible with 13-speed SRAM cassettes 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 gravel cyclists 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.
