Ratio 12-Speed Upgrade Kit: Unlock Eagle™ Performance on Your 11-Speed Shifter

Transform your gravel, road, or touring bike with seamless 12-speed precision—no need to replace your trusted SRAM 11-speed shifters. Our Ratio 12-Speed Upgrade Kit bridges the gap, letting you harness the legendary 500–520% gear range of SRAM Eagle™ derailleurs while maintaining crisp, evenly spaced shifts. Compare that to a standard 50/34 chainset with an 11-28 cassette (just 374% range), and the advantage is clear.

What’s Included:

• Custom 12-speed ratchet: Optimized for Eagle™ derailleur compatibility
• Cable fin & rear-facing cable stop: Ensures smooth routing for all frame types
• Hardware kit: Screws, circlips, and a chainstay sticker for hassle-free installation

Compatibility Checklist:

✅ Works With:
– SRAM 11-speed shifters (Red™, Force™, Rival™, Apex™) or 10-speed S-700
– Eagle™ XX1™/X01™ derailleurs (GX™ requires our Wide Upgrade Kit)
– SRAM Eagle™ 12-speed cassettes & chains

❌ Not Compatible:
– SX™, NX™, or riveted GX™ derailleurs (non-replaceable cable fins/pulleys)

Why Upgrade?

• Extended Range: Conquer steep climbs and sprint flats with a 12-speed spread.
• Cost-Effective: Skip buying new shifters—repurpose your existing setup.
• Universal Fit: Rear-exit cable design adapts to unconventional frame geometries.

Ideal for: Cyclists seeking pro-level gearing versatility without a full groupset overhaul. Pair with a 1×12 chainring for a streamlined, adventure-ready drivetrain.

Note: Aftermarket cassettes may affect performance. For optimal results, use genuine SRAM Eagle™ components.
