Sram Red AXS XPLR E1
The New Era of Gravel.
The RED XPLR E1 is a 13Speed masterpiece designed specifically for the 10-46T XPLR cassette. By adopting the "Full Mount" architecture pioneered in Sram’s Eagle Transmission, this derailleur eliminates the derailleur hanger; the weakest link in any traditional drivetrain. This creates a rock-solid connection that ensures perfect shifting alignment for the life of the bike, while offering a level of impact resistance that can survive the most grueling gravel events in the world.
Why the RED XPLR E1 is the Gravel Benchmark:
-
Hangerless Full Mount: By mounting directly to the frame (requires UDH interface), the derailleur is perfectly aligned with the cassette. There are no adjustment screws (limit screws) or B-gap adjustments required. Setup is instant and permanent.
-
13Speed Precision: Designed exclusively for 1X systems, the 13Speed range provides tighter steps in the middle of the cassette for better cadence control, while the 460% range conquers the steepest gravel inclines.
-
The Magic Wheel: The lower pulley features an inner ring that continues to spin even if a stick or debris enters the pulley cage. This prevents the chain from jamming and protects your derailleur from catastrophic failure mid-race.
-
MTB-Inspired Clutch: Features a heavy-duty spring clutch derived from Sram’s world-class mountain bike derailleurs. This provides unparalleled chain management, keeping your bike silent and your chain secure over the roughest washboard roads.
-
Rebuildable & Replaceable: In a nod to long-term ownership, many parts of the RED XPLR E1 are replaceable and rebuildable. You can swap out the outer link or the pulley cage assembly if they get damaged, rather than replacing the entire unit.
-
AXS Wireless Connectivity: Part of the proven AXS ecosystem, offering lightning-fast wireless shifting, customizable controls via the AXS app, and full compatibility with existing AXS batteries.

The Alegro Perspective: This is a "generational" upgrade. The shift quality of the Hangerless RED XPLR is so fast and so consistent that traditional derailleurs feel like ancient technology in comparison. We recommend this for the dedicated gravel racer who is tired of bent hangers and "vague" shifting. It’s a massive investment, but it’s the last derailleur you’ll ever have to adjust. It’s simply the strongest, smartest derailleur Sram has ever made.
