📌 Product Description

The SRAM AXS Ultralight Carbon Upgrade Kit is designed for riders chasing every gram. All structural components are crafted from premium prepreg carbon, molded at 20,000 psi, delivering strength equal to OEM parts with a major reduction in weight.

A full conversion saves up to ~100 g, bringing total derailleur weight down to ~210 g in optimized builds. Because Force and Red (D1/E1) share identical motor units, you can repurpose a Force derailleur into a build lighter than Red OEM at a fraction of the cost.

33T and 36T cages are available (36T body shipping end of year). D1 versions are directly compatible with 36T cassettes for expanded range setups.

🔥 Highlights

• Massive Weight Savings: Full upgrade reduces weight by up to ~100 g. Lightest builds as low as ~210 g (Red/Force E1).

• Premium Carbon Construction: Made from top-grade prepreg carbon, formed under 20,000 psi pressure, ensuring stiffness and durability equal to OEM.

• Broad Compatibility: Supports SRAM AXS D1 & E1 platforms (Red, Force, Rival, including XPLR).

• Modular Options: Choose from 33T / 36T cages, inner & outer arms, link plates, or the complete kit.

• Smart Upgrade Path: Force and Red (D1/E1) share the same motor – build a superlight RD from a used Force unit, lighter than stock Red!

• 36T Ready: 36T main cage expected by year-end; D1 versions are directly compatible with 36T cassettes.
