12 Speed Road Ratchet

This ratchet allows you to pair 10 or 11 speed mechanical SRAM shifters and a 1x-specific SRAM Exact Actuation* derailleur with a 12 speed SRAM 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.

NOTE: You will need to replace your 11 speed jockey wheels with SRAM eTap* AXS*  compatible ones. We offer some in our 1×12 Road Upgrade kit.
