Ratio Technology 1x13C Upgrade Kit

This upgrade kit allows you to pair 10 or 11 speed mechanical SRAM shifters and a SRAM 1x-specific Exact Actuation* derailleur with a Campagnolo Ekar* 13 speed cassette and chain. You’ll gain all the advantages of greater gear range and closer gear ratios without needing a whole new groupset.

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

The Ratio 1x13C Upgrade Kit allows you to operate a Campagnolo 13 speed Ekar* cassette and chain with your existing SRAM road 10 or 11 speed shifters and 1x-specific SRAM Exact Actuation* derailleur. Pair with our Ratio Ring for a 13 speed drivetrain with a minimum of new components.

Using a 1x13C Upgrade Kit provides a number of benefits:

  • Greater gear range and/or closer gear ratios than 11 or 12 speed
  • No need to purchase new shifters and derailleurs to upgrade to 13 speed
  • No batteries to charge
  • The reliability, serviceability and low weight of mechanical shifting
  • #humanpowered

In your kit you will find:

  1. Ratio 1x13C ratchet, with shift spacing specially designed for Campagnolo Ekar* cassettes
  2. Ratio 12 tooth jockey wheels with stainless Enduro bearings and labyrinth seals, specifically designed for Ekar* chains
  3. M2.5 screw for shifter ratchet replacement
  4. Ratio chainstay sticker

To use this kit you will need:

  1. SRAM 10 or 11 speed road shifters. If using 10 speed shifters you will also need a Ratio cable spool
  2. SRAM 1x derailleur from the Force 1*, Rival 1* or Apex 1* groups, or a SRAM 1x derailleur from the 11 speed MTB groups with a Ratio cable finand, if necessary for cable routing, a Ratio rear exit cable stop fitted. Ensure your derailleur has sufficient capacity for your chosen cassette size; note that 42t max derailleurs will shift perfectly on 10-44t cassettes.
  3. A Campagnolo Ekar* 13 speed cassette
  4. A Campagnolo Ekar* 13 speed chain
  5. A chainring compatible with the Ekar* chain, such as our Ratio Ring
  6. An N3W* freehub body
