This upgrade kit 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.
The Ratio 1×12 Road Upgrade Kit 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
- 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
Kit Includes
Ratio 1×12 Road ratchet, with shift spacing specially designed for AXS™ 12 speed cassettes
Ratio 12 tooth jockey wheels with stainless Enduro bearings and labyrinth seals, specifically designed for AXS™ Flattop™ 12 speed chains
M2.5 screw for shifter ratchet replacement
Ratio chainstay sticker
To use this kit you will need:
SRAM 10 or 11 speed road shifters. If using 10 speed shifters you will also need a cable spool available separately here
SRAM 1x derailleur from the Force 1™, Rival 1™ or Apex 1™ groups
A SRAM 12 speed eTap™ AXS™ 12 speed cassette from the Red™, Force™ or Rival™ groups
A SRAM 12 speed eTap™ AXS™ 12 speed chain from the Red™, Force™ or Rival™ groups
A chainring compatible with the 1×12 speed eTap™ AXS™ groups
An XDR™ freehub.
To fit your ratchet to SRAM shifters for hydraulic brakes, see the following video***
*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™
***Please note that modifying these components may void the original SRAM warranty. Ratio Technology Limited is in no way linked to SRAM LLC
