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.
