SRAM 2×12 Road Upgrade Kit – Mechanical Shifting Meets 12-Speed Performance
Transform your existing SRAM 11-speed mechanical road groupset into a high-performance 12-speed system without switching to electronic shifting. This upgrade kit lets you pair your current SRAM 11-speed shifters and 2x rear derailleur with 12-speed eTap AXS cassettes and Flattop chains, delivering smoother gear transitions and expanded range.
Why Upgrade to 12-Speed?
- Wider Gear Range: Enjoy closer ratios or extended range compared to 11-speed setups.
- Cost-Effective: Save over $1,000 vs. full wireless electronic upgrades (Force/Apex builds).
- Lighter Weight: Reduce your bike’s weight by up to 382g (disc brake setups).
- No Batteries: Reliable mechanical shifting—no charging required.
- Flawless Compatibility: Works seamlessly with SRAM Red, Force, Rival, or Apex 11-speed mechanical groups.
What’s Included?
- 12-Speed Road Ratchet: Precision-engineered for AXS cassette spacing.
- 11T Jockey Wheels: Stainless steel Enduro bearings + labyrinth seals, optimized for Flattop chains.
- Installation Hardware: M2.5 screw for easy ratchet replacement.
