Cable Spool

Use this cable spool (or drum, or bobbin, or reel…) as a SRAM 11 speed road shifter repair kit, or to fit a Ratio Upgrade Kit to your SRAM 10 speed road shifters.

Please note that the cable spool is not required for newer models of 10 speed shifters; some of these shifters are already 11 speed compatible. For more information on compatibility and how to identify your shifter, check our guide.

SKU: 0016 Category:

In combination with a Ratio 12 speed ratchet, the Ratio cable spool allows you to upgrade SRAM 10 speed road shifters to 12 speed. Additionally, the spool can be used as a replacement part to repair damaged or broken SRAM 11 speed road shifters.

  • Don’t scrap your 10 speed shifters – upgrade them to 12 speed with a Ratio spool!
  • With a spool fitted, 10 speed shifters are also compatible with SRAM 11 speed ratchets
  • Replace a damaged 11 speed cable spool, repairing your broken 11 speed Red*, Force*, Rival* or Apex* shifter

Note: If you fit the Ratio cable spool to 10 speed shifters, you will be able to fit 11 or 12 speed ratchets. To re-fit the original 10 speed ratchet just replace the original cable spool.

In your kit you will find:

  1. Ratio cable spool
  2. M2.5 screw for shifter disassembly

To use the spool you will need:

  1. SRAM 10 or 11 speed road shifters from the Red*, Force*, Rival*, Apex* or S Series* groups.

To fit your spool to SRAM shifters for cable brakes, see the following video. When you remove the red-coloured (11 speed) or white-coloured (10 speed) SRAM spool, replace it with your new black-coloured Ratio spool. Note that an 11 speed shifter is shown, but the process is very similar for 10 speed models**.

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.
