Business in the front, and now even more party in the back!

We introduced you to the Garbaruk Mullet Drivetrain Kit for Sram 11-Speed. Now you can go one step further and ride a mechanical 12-Speed Mullet.
The Ratio Technology 1×12 Wide Upgrade Kit allows you to pair 11-Speed mechanical SRAM shifters with 12-Speed Sram Eagle or 11-Speed Sram Force, Rival and Apex (when using the Garbaruk RD cage) rear derailleurs and 10-52T 12-Speed cassettes.
This is the neatest solution on the market to gaining all the performance advantages of a wide-range 1×12 drivetrain on a gravel, road or touring bike without the expense of electronic shifting.

Ratio Technology 1×12 Wide Upgrade Kit – Forward Cable Exit

This upgrade kit can be used in two ways:

Option 1:
Modify your 11-Speed mechanical SRAM Road/Gravel shifter with the 12-Speed Ratio ratchet and use your 11-Speed SRAM Road/Gravel derailleur modified with the Garbaruk RD cage with a wide-range 12-Speed cassette.
→ your Road/Gravel shifter is now 12-Speed
→ your Road/Gravel rear derailleur can now take on a 10-52T 12-Speed cassette

Option 1:
Modify your 11-Speed mechanical SRAM Road/Gravel shifter with the 12-Speed Ratio ratchet and use your 11-Speed SRAM Road/Gravel derailleur modified with the Garbaruk RD cage with a wide-range 12-Speed cassette.

Option 2:
Modify your 11-Speed mechanical SRAM Road/Gravel shifter with the 12-Speed Ratio ratchet AND modify your SRAM Eagle 12-Speed rear derailleur with the Ratio fin and barrel adjuster to use a wide-range 12-Speed cassette.
→ your Road/Gravel shifter is now 12-Speed
→ your Sram Eagle has now a modified pull ratio to work with your modified Road/Gravel shifter and 10-52T 12-Speed cassettes.

Option 2:
Modify your 11-Speed mechanical SRAM Road/Gravel shifter with the 12-Speed Ratio ratchet AND modify your SRAM Eagle 12-Speed rear derailleur with the Ratio fin and barrel adjuster to use a wide-range 12-Speed cassette.
