NEW Ratio 2x12 Road Upgrade Kit

The Ratio 2×12 Road Upgrade Kit allows you to operate a SRAM eTap™ AXS™ 12 speed road cassette and 12 speed Flattop™ chain with your existing SRAM 11 speed mechanical road shifters and 11 speed 2x-specific Exact Actuation™ rear derailleur.

Using a 2×12 Road Upgrade Kit gives you the following advantages:

• Greater gear range and/or closer gear ratios than 11 speed
• Lower cost than wireless electronic. Save $1786 on a Force™ disc build; $1170 saving on a Force™ rim brake build*
• Lower weight. Save 382g on a Force™ disc build & 222g on a Force™ rim brake build**
• No batteries to keep charged
• The reliability and serviceability of mechanical shifting
• #humanpowered

In your kit you will find:

1. Ratio 12 speed Road ratchet, with shift spacing specially designed for AXS™ 12 speed road cassettes
2. Ratio 11 tooth jockey wheels with stainless Enduro bearings and labyrinth seals, specifically designed for Flattop™ 12 speed chains & 2x-specific SRAM road rear derailleurs
3. M2.5 screw for shifter ratchet replacement

To use this kit you will need:

How is this kit different to the 1×12 Road Upgrade kit:

The 1×12 & 2×12 Road Upgrade kits are very similar, they both use a 12 speed Road ratchet. However, the 2×12 kit uses 11T jockey wheels, specifically designed for SRAM 2x-compatible rear-derailleurs whereas the 1×12 kit has 12T Jockey wheels.
