As cyclists, we design the products we want on our bikes. The Ratio 12-Speed Upgrade Kit allows you to operate an Eagle derailleur with your existing SRAM 11-speed shifters, gaining an unbeatable 500% or 520% range and 12 evenly spaced gears on your gravel, road or touring bike. For reference, a traditional 50/34 compact chainset with 11-28 cassette provides only 374% range.

1. Ratio 12-speed ratchet, with shift spacing specially designed for Eagle derailleurs
2. Ratio cable fin, replacing the existing cable fin on an Eagle derailleur
3. Ratio rear-facing cable stop with adjuster, routing the cable out of the back of the derailleur for compatibility with all frame designs
