Ratio Technology 12 Speed Road Ratchet

 

This ratchet allows you to pair 10 or 11 speed mechanical SRAM shifters and a 1x-specific Exact Actuation™ derailleur with a 12 speed eTap™ AXS™ cassette and chain. You’ll gain all the advantages of greater gear range and closer gear ratios without the expense or weight of electronic shifting.

NOTE: You will need to replace your 11 speed jockey wheels with SRAM eTap™ AXS™  compatible ones. We offer some in our 1×12 Road Upgrade kit.

View our Support page here. For more information, check our compatibility guide.

The Ratio 12 Speed Road Ratchet allows you to operate a SRAM eTap™ AXS™ 12 speed cassette and chain with your existing SRAM road 10 or 11 speed shifters and 1x-specific Exact Actuation™ derailleur.

Using a 1×12 Road kit gives you following advantages:

  • Greater gear range and/or closer gear ratios than 11 speed
  • Lower cost than wireless electronic. Save $1800 on a Force™ build; $800 saving on a Rival™ build
  • Lower weight. Save 160g on a Force™ build; 220g on a Rival™ 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 cassettes
  2. M2.5 screw for shifter ratchet replacement

NOTE: On some older shifters, the reach adjuster will not spin freely when it bottoms out. Stop turning the reach adjuster screw as soon as you encounter resistance.

*This calculation is based upon SRPs for all components. It assumes that the purchaser already owns the SRAM shifters and derailleur required to use the kit.

**The calculation is based upon comparing Ratio/Rival™ 1 to Rival eTap™ AXS™ and Ratio/Force ™1 to Force AXS™
